<Device software processing>
Next, processing of the design support device 1 used in the design support system will be explained. FIG. 3 is a flowchart illustrating an example of the pillar placement process of the design support apparatus 1 described in the present application. The column placement process is a process of automatically placing columns during the design of a building using a CAD system. In the following description, a process for arranging columns such as rigid-frame columns made of steel materials such as H-shaped steel and WH-shaped steel in a building with a heavy steel frame rigid-frame structure will be exemplified and explained. H-shaped steel used as a steel material is a steel material that has an H-shaped cross section. Moreover, the WH section steel referred to in the present application is a WH section steel that has a cross-sectional shape obtained by combining two H sections in the longitudinal direction, as described in Japanese Patent No. 6382363. That is, in this application, as the rigid-frame pillar, a rigid-frame pillar formed using H-shaped steel, and a rigid-frame pillar formed using WH-shaped steel, which has a shape in which H-shaped steel is overlapped in the horizontal direction of an H character, are used. This will be explained by illustrating an example.

The control unit 10 included in the design support device 1 executes a column arrangement process by executing various programs such as a CAD program 110 and a design support program 111. The control unit 10 included in the design support device 1 executes CAD processing (step S1). The CAD processing in step S1 indicates design support processing using a CAD system. In CAD processing, the CAD information database 112 is accessed, CAD data such as CAD data recorded in association with the client ID and CAD data that is a pre-recorded basic plan is extracted, and content is added and added as appropriate. This is done by making modifications.

The control unit 10 of the design support device 1 receives an input from the input unit 13 of a placement command for automatic column placement (step S2), and selects a ramen pillar, etc. that has already been placed on the floor targeted for automatic column placement. All pillars are removed (step S3).

FIG. 4 is an explanatory diagram showing an example of an image displayed on the display section 14 included in the design support apparatus 1 described in the present application. FIG. 4 shows, as a drawing of a building based on CAD data, a floor plan displayed on the display unit 14 after removing the rigid-frame pillars in step S3 in the pillar arrangement process illustrated in FIG. In FIG. 3, the positions of structures such as walls and windows where pillars cannot be placed are indicated by rectangles with thin solid lines or thick solid lines. Structures such as outer walls, wing walls, and partition walls are shown in the foreground plan, but all the columns have been removed and are not displayed.

After removing the columns, the control unit 10 derives the minimum number of columns to be arranged on the floor based on the structure of the building (step S4). In step S4, the structural strength is calculated based on structural factors such as the height, shape, floor, materials used, and weight of the building, and the minimum required number of columns to be arranged is derived.

An example of deriving the minimum number of pillars to be arranged, which is executed in step S4, will be described. The minimum arrangement number derived in step S4 is the minimum required amount of rigid-frame columns determined for each floor and each horizontal direction (X-axis direction, Y-axis direction) of the building. Assuming that the minimum number of arranged pieces is n, the minimum number of arranged pieces is derived by the following formula 1.

In Equation 1, the layer shearing force due to the seismic force and the rigid frame column standard load shearing force are read from the definition of an external file recorded in the structural information database 113, for example. Further, for each floor and in each direction, whether or not the minimum number of Ramen pillars are arranged is determined using the following equation 2.

In the above formula 2, the total number of converted rigid-frame columns indicates the total when columns other than rigid-frame columns using H-section steel are converted to rigid-frame columns using H-section steel. Columns other than rigid-frame columns using H-shaped steel are converted using the following formula 3.

_i n _eq = β・α _WH・γ _OH・γ _1L …Formula 3
However, _i n _eq : Number of rigid-frame columns using H-shaped steel
α _WH : Rigidity multiplier for rigid frame columns using WH type steel
γ _OH : Rigidity increase/decrease rate at overhang part
γ _1L : Rigidity increase/decrease rate in the 1st floor rigid frame column in the column long range

In Equation 3, the rigidity magnification and rigidity increase/decrease rate are read from, for example, an external file definition recorded in the structural information database 113 for each item of building floor number, target floor, and floor height. Note that the column long range is defined as a combined area of indoor floors where the "floor height" is a negative value. In addition, variables etc. can be set as appropriate according to the specifications.

After deriving the minimum arrangement number, the control unit 10 executes a temporary Ramen pillar arrangement process (step S5). The temporary Ramen pillar arrangement process in step S5 is a process of temporarily arranging pillars in positions where pillars of the building can be arranged so that the number of pillars to be arranged is maximized. The positions where the pillar can be placed in step S5 include positions that are not candidates for placement, positions that are physically impossible to place due to the presence of other structures, positions that cannot be placed due to regulations, and other conditions. Indicates the positions excluding positions that should not be allowed, such as positions that are not allowed to be placed.

FIG. 5 is a flowchart illustrating an example of a rigid frame pillar temporary arrangement process of the design support apparatus 1 described in the present application. The temporary Ramen pillar arrangement process executed as step S5 of the pillar arrangement process will be described. As the Ramen pillar temporary placement process, the control unit 10 of the design support device 1 sets placement lines in a grid pattern as a reference for arranging Ramen pillars on the building plan displayed on the display unit 14 (S501). .

FIG. 6 is an explanatory diagram showing an example of an image displayed on the display section 14 included in the design support apparatus 1 described in the present application. FIG. 6 shows a state in which placement lines have been set from the state shown in FIG. 4 through the process of step S501 of the temporary Ramen pillar placement process shown in FIG. The arrangement lines are a plurality of lines orthogonal to a grid pattern parallel to the X-axis direction (first horizontal direction) and the Y-axis direction (second horizontal direction) displayed on the CAD system, and in FIG. 6, the dotted lines It is shown in Further, in FIG. 6, the positions of structures such as walls and windows where pillars cannot be placed are indicated by rectangles. The arrangement lines are arranged in a lattice pattern so as to be orthogonal to each other as a plurality of straight lines passing through walls such as outer wall lines, wing walls, and partition walls having a length of at least a predetermined length such as 250 mm. In FIG. 6, dotted lines indicating placement lines are shown passing through rectangles indicating walls and the like. Then, the rigid-frame noodles are placed on the set placement line. The building to be designed is designed based on a rectangular shape, and is displayed on the operation screen of the CAD system so that the walls are parallel to the X axis (horizontal) or the Y axis (vertical). In the following explanation, regarding directions such as the arrangement direction of members in the blueprint, the direction toward the blueprint displayed on the display unit 14, that is, the direction along the X axis, will be expressed as the left-right direction. , the direction along the Y axis is expressed as the vertical direction.

Returning to the flowchart of FIG. 5, the control unit 10 determines the arrangement direction of the pillars with respect to the set arrangement line (S502), and sets an arrangement possible area where the rigid-frame noodles can be arranged on the set arrangement line (S503). . Step S502 is a process of determining which direction to arrange the rigid-frame pillars from among two orthogonal directions, the X-axis direction and the Y-axis direction. For example, it is determined that the rigid-frame columns should be arranged from the X-axis direction. Basically, the same direction as the direction determined for the first floor is determined for other floors such as the second and third floors.

FIG. 7 is an explanatory diagram showing an example of an image displayed on the display unit 14 included in the design support apparatus 1 described in the present application. FIG. 7 shows a state in which an arrangement possible area has been set by the processing in step S503 of the Ramen pillar temporary arrangement processing shown in FIG. 5 from the state shown in FIG. 6. The placement possible area is a long rectangular area set on the placement line excluding the area where the rigid-frame pillar cannot be placed. Areas in which Ramen pillars cannot be placed, which are excluded from the placement area, are areas where walls such as exterior walls, wing walls, partition walls, and other structures such as windows and sashes are already placed on the placement line. It is. In FIG. 7, a rectangle whose inside is indicated by diagonal lines and whose outer shape is indicated by thin lines indicates an arrangement possible area. As illustrated in FIG. 7, the arrangement possible area is set for each of the arrangement lines parallel to the X-axis direction and the arrangement lines parallel to the Y-axis direction.

Returning to the flowchart of FIG. 5, the control unit 10 temporarily arranges rigid-frame columns at all possible positions so that the number of rigid-frame columns of H-beam steel becomes the maximum number in the set possible arrangement area. (S504).

FIG. 8 is an explanatory diagram showing an example of an image displayed on the display unit 14 included in the design support apparatus 1 described in the present application. FIG. 8 shows that the ramen pillars are temporarily placed by the process of step S504 of the ramen pillar temporary placement process exemplified in FIG. It shows the condition. In FIG. 8, the arranged rigid-frame pillars are shown as an H-shaped cross section. FIG. 8 shows an example of arranging rigid-frame columns made of H-beam steel whose cross section is 250 mm in the longitudinal direction. The temporarily arranged Ramen pillars are arranged so as to reach the maximum number in the longitudinal direction of the arrangable area set as a rectangular area, so the number of ramen pillars to be arranged in the arrangable area is expressed by the following equation 4.

Maximum number of pieces that can be placed within the placement area = {quotient of Larea/(2・Lp)}+remainder of {Larea/(2・Lp)}/Lp...Formula 4
However, Larea: Length in the major axis direction of the placement area Lp: Length in the longitudinal direction of the cross section of the rigid frame column to be placed

In FIG. 8, the length of the possible arrangement area A between the left end wall and the right sash shown as a rectangle is 3000 mm, and six rigid-frame columns made of H-beam steel are temporarily arranged. The length of the arrangable area B between the sash on the right side of the arrangable area A and the sash further to the right indicated by a rectangle is 1500 mm, and three Ramen pillars are temporarily arranged. The length of the arrangable area C between the sash on the right side of the arrangable area B and the sash further to the right indicated by a rectangle is 750 mm, and two Ramen pillars are temporarily placed. The length of the arrangable area D between the sash on the right side of the arrangable area C and the right end wall is 2250 mm, and five rigid-frame noodles are temporarily arranged. Similar processing is performed on all placement possible areas on all placement lines, thereby performing the temporary placement in step S504.

As described above, the temporary Ramen pillar arrangement process is executed.

Returning to the flowchart of FIG. 3, the control unit 10 of the design support apparatus 1 executes the structural index adjustment process (step S6). The structural index adjustment process in step S6 is a process of deriving a structural index, which is an index that numerically represents the arrangement state of the rigid-frame noodles, and removing the arranged rigid-frame columns based on the derived structural index.

FIG. 9 is a flowchart illustrating an example of the structural index adjustment process of the design support apparatus 1 described in the present application. The structural index adjustment process executed as step S6 of the column arrangement process will be described. As a structural index adjustment process, the control unit 10 of the design support apparatus 1 refers to the recorded contents of the structural information database 113 and derives a structural index that is an index that numerically represents the arrangement state of the rigid frame pillars (S601). The structural index derived in step S601 is based on a value based on the type of column to be placed, a value indicating the relationship between the minimum number of columns to be placed and the number of columns to be placed, and an eccentricity of the column to be placed with respect to the horizontal direction of the building. This is an index based on a numerical value and one or more numerical values indicating the status of pillars arranged as a group. The structural index is an index indicating the structural strength and stability of a building, and the higher the value, the better. For example, if rigid frame columns made of WH-shaped steel are arranged in a concentrated manner, the strength will increase locally, but the stability of the building as a whole will be poor due to local loads, and the strength as a whole will decrease. As a result, the structural index will be a low value.

An example of deriving the structural index derived in step S601 will be described. The structural index is a numerical value with a standard value of 80, an upper limit of 90, and a lower limit of 0. Derived as follows. The reference value of the structural index is recorded in the structural information database 113, and when deriving the structural index, the control unit 10 accesses the structural information database 113 and refers to the recorded reference value of the structural index.

When deriving the structural index, an additional value is derived as a numerical value based on the type of pillar to be placed, and is added to the reference value of the structural index. The additional value is calculated by deriving the WH rate standard value from the WH rate calculated as Equation 5 below based on the WH rate standard value table illustrated in Table 1 below, and further calculating the WH rate as illustrated in Table 2 below. It is derived by referring to the rate addition value table. The WH rate reference value table illustrated in Table 1 records the WH rate reference value table rate reference value in association with the relationship between the judgment floor and the number of floors of the building. The WH rate additional value table illustrated in Table 2 records the WH rate determination criteria and additional values in association with each other. The formula shown as Equation 5 and the various tables shown in Tables 1 and 2 are recorded in the structural information database 113, and the control unit 10 stores the information in the structural information database 113 when deriving the additional value based on the type of pillar to be placed. Access and refer to recorded contents.

WH rate = WH number/(WH number + H number) × 100...Equation 5
However, WH number: Number of rigid-frame columns using WH-shaped steel H number: Number of rigid-frame columns using H-shaped steel

Derivation of the addition value will be specifically explained. When deriving the additional value, the WH rate is calculated based on Equation 5 for the layout line of the floor and direction for which the structural index is to be derived. In the state of step S6 after first temporarily arranging the rigid-frame columns, all the rigid-frame columns use H-shaped steel, so the WH ratio is "0", but for example, if 1/4 of the rigid-frame columns If WH section steel is used, the WH ratio will be "25". Next, the WH rate reference value is determined by referring to the WH rate reference value table based on the number of floors of the target building and the target floor. For example, when the second floor of a three-story building is targeted, the WH rate reference value is "20". Then, based on the relationship between the WH rate calculated using Equation 5 and the WH rate reference value obtained with reference to the WH rate reference value table, the additional value is derived with reference to the WH rate conversion value table. For example, if the WH rate is "25" and the WH rate reference value is "20", the WH rate is 1.25 times the WH rate reference value, so the additional value is "-20". Further, for example, when all the rigid frame columns are made of H-beam steel, the WH ratio is "0", so the added value is "0". The additional value derived in this way as a numerical value based on the type of pillar to be arranged is added to the reference value of the structural index.

Further, as another numerical value required for deriving the structural index, an additional value is derived as a numerical value indicating the relationship between the minimum number of columns to be arranged and the number of columns to be disposed, and is added to the reference value of the structural index. The additional value is derived based on a rigid frame pillar placement standard table illustrated as Table 3 below. The ramen pillar placement amount reference table illustrated in Table 3 records the criteria for determining the amount of ramen pillar placement and additional values in association with each other. The standard table for the arrangement amount of Ramen pillars illustrated in Table 3 is recorded in the structural information database 113, and the control unit 10 uses the structural information database 113 and refer to the recorded contents.

Derivation of the addition value will be specifically explained. When deriving the additional value, the layout line of the floor and direction for which the structural index is to be derived is derived with reference to the rigid frame column placement standard table. For example, if the minimum number of arranged lines is 5 and the number of arranged lines is 6, the added value will be "+10". The additional value as a numerical value indicating the relationship between the minimum number of pillars to be arranged and the number of pillars to be arranged thus derived is added to the reference value of the structural index.

Further, as another numerical value required for deriving the structural index, an additional value is derived as a numerical value based on the eccentricity of the columns arranged with respect to the horizontal direction of the building, and is added to the structural index. The added value is derived based on an eccentricity determination standard table exemplified as Table 4 below. The eccentricity determination criteria table illustrated in Table 4 records eccentricity determination criteria and additional values in association with each other. The eccentricity determination standard table exemplified in Table 4 is recorded in the structural information database 113, and the control unit 10 uses the structural Access the information database 113 and refer to the recorded contents.

Derivation of the addition value will be specifically explained. When deriving the additional value, first, the eccentricity is calculated for the layout line of the floor and direction from which the structural index is to be derived. Based on the calculated eccentricity, an additional value is derived by referring to an eccentricity determination reference table. For example, if the calculated eccentricity is 18%, the additional value will be "-10". The additional value derived in this manner as a numerical value based on the eccentricity of the columns arranged with respect to the horizontal direction of the building is added to the reference value of the structural index.

Further, as other numerical values required for deriving the structural index, an additional value is derived as a numerical value indicating the status of the pillars arranged as a column group, and is added to the structural index. The added value is derived with reference to the pillar group determination criteria table exemplified as Table 5 below. The column group determination criteria table illustrated in Table 5 records additional values in association with the relationship between the structure of the column group and the number of rigid-frame noodles in the column group. The column group shown in the column group determination criteria table indicates a collection of one or more rigid frame columns arranged on the same arrangement line on the same floor at intervals of 250 mm. More specifically, in the placeable area set in step S503, all the rigid frame pillars placed in one placeable area are collectively defined as a pillar group. The composition of a column group refers to whether one or more rigid-frame columns included in one column group are only rigid-frame columns made of H-shaped steel, only rigid-frame columns made of WH-shaped steel, or a mixture of these. Show that. The column group determination criteria table illustrated in Table 5 is recorded in the structural information database 113, and the control unit 10 accesses the structural information database 113 to derive the added value related to the column group and the recorded contents.

Derivation of the addition value will be specifically explained. When deriving the additional value, based on the layout line of the floor and direction that is the target of the structural index, the composition of the column group included in the placement possible area on the layout line and the number of rigid-frame pillars included in the column group. Then, the additional value is derived by referring to the column group judgment criteria table. For example, if the number of rigid-frame columns included in the target column group is three, and all of the rigid-frame columns are made of H-beam steel, the additional value will be "-5".

As described above, the structure index is derived by adding all the additional values derived by various methods to the reference value. Note that the structural index has an upper limit and a lower limit, so by adding the additional value, if it exceeds the upper limit, it is derived as the upper limit "90", and if it is below the lower limit, it is derived as the lower limit "90". 0".

Returning to the flowchart of FIG. 9, the control unit 10 of the design support apparatus 1 determines whether there is a placement line for which the derived structural index is decreasing (S602). In step S602, the structural index derived for each floor and layout line is compared with a predetermined threshold set in advance, and it is determined whether there is a layout line whose structural index is lower than the threshold. For example, "0" is used as the threshold value. That is, if the derived structural index is "0" (including the case where it is derived as the lower limit value of 0 because it is below the lower limit), it is determined that it is a placement line with a lowered structural index.

In step S602, if it is determined that there is a placement line whose structural index has decreased (S602: YES), the control unit 10 selects the corresponding placement line as a target for consideration of whether or not the placed rigid-frame pillar can be removed. (S603). In step S602, if it is determined that there are multiple placement lines whose structural index is decreasing, the determination is made for each horizontal direction, and if there are multiple placement lines parallel to the X-axis direction, the lowest placement line is stepped. Select in S603. Furthermore, when there are multiple placement lines parallel to the Y-axis direction, the leftmost placement line is selected. In the subsequent processing, it is determined whether or not the Ramen pillar placed on the arrangement line selected in step S603 can be removed, and if removal is possible, the targeted Ramen pillar is removed.

The control unit 10 that has selected the placement line determines whether the number of placement lines for which the structural index was determined to have decreased in step S602 is less than or equal to the difference obtained by subtracting the minimum number of placement lines from the number of placement lines ( S604). In step S604, it is determined whether or not it is necessary to increase the strength after removing the rigid-frame pillars by comparing the number of placement lines whose structural index has decreased with the number of placement lines that is greater than or equal to the minimum number of placement lines. Specifically, if the number of placement lines whose structural index has decreased is greater than the difference between the number of placement lines and the minimum number of placement lines, it is determined that there is no significant decrease in strength due to the removal of the rigid frame columns. In addition, if the number of placement lines whose structural index has decreased is smaller than the difference between the number of placement lines and the minimum number of placement lines, it is determined that it is necessary to change the type of steel material to increase the strength after removing the rigid frame column. do.

In step S604, if it is determined that the number of placement lines whose structural index has decreased is greater than or equal to the difference between the number of placement lines and the minimum number of placement lines (S604: YES), the control unit 10 controls the placement line selected in step S603. It is determined whether three or more Ramen pillars are consecutively arranged on the line (S605). In step S605, continuous rigid-frame noodles refer to rigid-frame columns arranged at intervals of a predetermined length, such as 250 mm, within the same arrangement area. Even if they are in the same arrangement area, if they are separated by more than a predetermined length, they are considered not to be continuous.

In step S605, if it is determined that three or more Ramen pillars are consecutively arranged (S605: YES), the control unit 10 removes the second Ramen pillar (S606), returns to Step S605, and continues Repeat the process. The second rigid-frame pillar to be removed in step S606 refers to the second rigid-frame pillar from the left among three or more consecutive rigid-frame pillars on the left and right, if the target is a rigid-frame pillar related to the arrangement line parallel to the X-axis direction. The second Ramen pillar will be removed. Furthermore, if the target is a rigid-frame pillar along a line parallel to the Y-axis direction, the second rigid-frame pillar from the bottom among three or more consecutive rigid-frame pillars is removed. The determination process in step S605 and the removal process in step S606 are repeated until there are no longer three or more consecutively arranged Ramen pillars.

In step S605, if it is determined that there are no rigid frame columns arranged in succession (S605: NO), the control unit 10 returns to step S602 and determines whether there are other arrangement lines whose structural index has decreased. is determined, and the subsequent processing is repeated.

In step S604, if the number of placement lines whose structural index has decreased is less than the difference between the number of placement lines and the minimum number of placement lines (S604: NO), the control unit 10 performs the following on the placement line selected in step S603: It is determined whether three or more Ramen pillars are consecutively arranged (S607).

In step S607, if it is determined that three or more Ramen pillars are consecutively arranged (S607: YES), the control unit 10 removes the third Ramen pillar (S608), returns to Step S607, and continues Repeat the process. The third rigid-frame pillar to be removed in step S608 refers to the third rigid-frame pillar from the left among three or more consecutive rigid-frame pillars on the left and right, if the target is a rigid-frame pillar related to the arrangement line in the direction parallel to the X-axis direction. The second Ramen pillar will be removed. In addition, if the target is a rigid-frame pillar according to an arrangement line parallel to the Y-axis direction, the third rigid-frame pillar from the bottom among three or more consecutive rigid-frame pillars vertically is to be removed. By leaving the continuous first and second rigid-frame columns, it is easier to change the type of rigid-frame columns from H-shaped steel to WH-shaped steel in subsequent processing, and the final strength is prevented from decreasing. I can do it. The determination process in step S607 and the removal process in step S608 are repeated until there are no longer three or more consecutively arranged Ramen pillars.

In step S607, if it is determined that there are no rigid-frame pillars arranged in succession (S607: NO), the control unit 10 returns to step S602 and determines whether there are other arrangement lines whose structural index has decreased. is determined, and the subsequent processing is repeated.

In step S602, if it is determined that there is no placement line whose structural index has decreased (S602: NO), the control unit 10 performs the structural index adjustment process without executing the subsequent processes shown as steps S603 to S608. finish.

The structural index adjustment process is executed as described above.

Returning to the flowchart of FIG. 3, the control unit 10 of the design support apparatus 1 determines whether the number of arranged pieces is equal to or greater than the minimum number of pieces of arranged pieces derived in step S4 (step S7).

If it is determined in step S7 that the number of arranged pieces is equal to or greater than the minimum number of pieces arranged (step S7: YES), the control unit 10 executes the first eccentricity adjustment process (step S8). The first eccentricity adjustment process in step S8 is when it is determined that the eccentricity does not satisfy a predetermined condition and there is a bias in the arrangement of the rigid-frame columns, the eccentricity of the rigid-frame columns that are concentrated in order to adjust the eccentricity is adjusted. This is a process of removing.

FIG. 10 is a flowchart illustrating an example of the first eccentricity adjustment process of the design support apparatus 1 described in the present application. The first eccentricity adjustment process executed as step S8 of the column arrangement process will be described. As the eccentricity adjustment first process, the control unit 10 of the design support apparatus 1 derives the eccentricity direction for the layout line of the floor and direction that is the target of eccentricity adjustment (S801). The eccentric direction is derived based on the eccentricity.

The control unit 10 evaluates each arrangement line parallel to the derived eccentric direction (S802). In step S802, a score is calculated for each placement line according to a predetermined calculation method, and evaluation is performed based on the calculated score. The score is calculated, for example, by summing up each score shown in a placement line evaluation table exemplified as Table 6 below. The placement line evaluation table is set based on various factors such as the eccentricity after removal, the relationship with the outer wall, the number of columns, the positional relationship with other placement lines, and the relationship with columns on the upper and lower floors.

Based on the evaluation result, the control unit 10 determines whether there is a placement line that allows removal of all the rigid-frame pillars (S803). In step S803, for example, a placement line for which the total score exceeds 100 as a result of the evaluation in step S802 is determined to be a placement line from which all the rigid-frame noodles can be removed.

If it is determined in step S803 that there is a placement line from which all the rigid-frame noodles can be removed (S803: YES), the control unit 10 removes all the rigid-frame noodles on the corresponding placement line (S804), and proceeds to step S802. Go back and repeat the process.

In step S803, if it is determined that there is no arrangement line that allows removal of all the rigid frame columns (S803: NO), the control unit 10 calculates the eccentricity again, and sets the calculated eccentricity to a predetermined value such as 15%. It is determined whether or not the value is larger than that (S805).

In step S805, if it is determined that the calculated eccentricity is larger than the predetermined value (S805: YES), the control unit 10 selects a placement line on which a plurality of rigid frame columns are highly evaluated (S806). In step S806, a placement line in which a plurality of rigid-frame columns using H-beams are arranged is selected from among the highly evaluated placement lines for which the score of the evaluation in step S802 is equal to or higher than a predetermined value.

In step S806, the control unit 10 determines whether or not there is a rigid-frame pillar located on the outer wall line on the selected placement line (S807).

In step S807, if it is determined that there is no rigid-frame pillar located on the exterior wall line (S807: NO), the control unit 10 selects the rigid-frame pillar closest to the intersection of the selected placement line and the exterior wall line as a removal target (S808 ).

In step S807, if it is determined that there is a rigid-frame pillar located on the outer wall line (S807: YES), the control unit 10 determines that the end of the corresponding rigid-frame pillar is within a predetermined distance such as 500 mm from the nearest entry/exit corner. It is determined whether or not (S809). Note that in step S809, if the entrance/exit corner itself does not exist, it is determined that the distance is not within the predetermined distance.

In step S809, if it is determined that the end of the corresponding rigid-frame pillar is within a predetermined distance from the entrance/exit corner (S809: YES), the control unit 10 selects the leftmost rigid-frame pillar among the plurality of rigid-frame pillars on the target arrangement line. The (lower) Ramen pillar is selected as a removal target (S810). In step S810, if the selected placement line is parallel to the X-axis direction, the leftmost rigid-frame pillar is selected. Furthermore, if the selected arrangement line is parallel to the Y-axis direction, the lowermost rigid-frame pillar is selected.

In step S809, if it is determined that the end of the corresponding rigid-frame pillar is not within a predetermined distance from the entry/exit corner (S809: NO), the control unit 10 selects the longest side of the outer periphery including the selected placement line. (S811), and the rigid-frame pillar closest to the center of the building on the selected side is selected as a removal target (S812).

The control unit 10 removes the rigid frame pillar selected in step S808, S810, or S812 (S813). That is, if the eccentricity is greater than a predetermined value in step S805, a rigid-framed pillar to be removed is selected from various conditions, and the selected rigid-frame pillar is removed.

After removing the rigid frame pillars, the control unit 10 evaluates each placement line again (S814), returns to step S805, and repeats the subsequent processing.

In step S805, if it is determined that the calculated eccentricity is less than or equal to the predetermined value (S805: NO), the control unit 10 performs the first eccentricity adjustment without executing the subsequent processes shown in steps S806 to S814. Finish the process. As described above, the eccentricity adjustment first process determines the bias based on the eccentricity, and if the eccentricity is larger than a predetermined value such as 15%, the removable H This is a process to remove rigid frame columns of shaped steel. The eccentricity can be improved by removing the rigid frame columns placed on the placement line where it has been determined that the deviation has occurred.

As described above, the first eccentricity adjustment process is executed.

Returning to the flowchart of FIG. 3, the control unit 10 of the design support apparatus 1 determines whether the number of arranged pieces is equal to or greater than the minimum number of pieces arranged (step S9).

If it is determined in step S9 that the number of arranged noodles is equal to or greater than the minimum number of arranged noodles (step S9: YES), the control unit 10 executes a rigid frame pillar removal process (step S10). The Ramen pillar removal process in Step S10 means that if the number of Ramen pillars is still equal to or greater than the minimum number of Ramen pillars even after the removal of Ramen pillars by the first eccentricity adjustment process in Step S8, if further removal is possible, then This is a process to remove pillars.

FIG. 11 is a flowchart showing an example of the rigid frame pillar removal process of the design support apparatus 1 described in the present application. The rigid frame pillar removal process executed as step S10 of the pillar arrangement process will be described. As a rigid frame pillar removal process, the control unit 10 of the design support device 1 derives the eccentric direction for the layout line of the floor and direction that is the target of eccentricity adjustment (S1001), and calculates each layout line parallel to the derived eccentric direction. An evaluation is performed (S1002). The process of deriving the eccentric direction and evaluating the arrangement line in steps S1001 and S1002 is substantially the same as the process of steps S801 and S802 of the eccentricity adjustment first process described using FIG. However, the arrangement line evaluation table may be changed to a different content from the first eccentricity adjustment process.

Based on the evaluation results, the control unit 10 determines the presence or absence of a placement line that has a high evaluation and the number of arranged rigid-frame noodles is equal to or greater than a predetermined upper limit number (S1003). In step S1003, it is determined whether or not there is a placement line in which a predetermined upper limit number or more of rigid frame columns using H-beams are arranged among the highly evaluated placement lines for which the score of the evaluation in step S1002 is equal to or greater than a predetermined value.

If it is determined in step S1003 that there is a placement line that has a high evaluation and the number of rigid-frame pillars to be placed is equal to or greater than the predetermined upper limit number (S1003: YES), the control unit 10 selects the corresponding placement line (S1004) .

The control unit 10 determines whether there is a rigid-frame pillar that satisfies the removal conditions on the selected arrangement line (S1005). In step S1005, assuming that each rigid-frame pillar placed on the selected placement line is removed, the conditions for establishing it, such as the eccentricity exceeding a predetermined value or being less than the minimum number of placement columns, are not satisfied. Determine whether the situation will occur. If there is a Ramen pillar whose establishment condition is not satisfied even if it is removed, it is determined that there is a Ramen pillar that satisfies the removal condition. If the conditions are not satisfied even if any Ramen pillar is removed, it is determined that there is no Ramen pillar that satisfies the removal conditions.

In step S1005, if it is determined that there is a rigid-frame pillar that satisfies the removal conditions (S1005: YES), the control unit 10 determines whether or not there is a rigid-frame pillar located on the outer wall line on the selected placement line (S1006). ).

If it is determined in step S1006 that there is no rigid-frame pillar located on the exterior wall line (S1006: NO), the control unit 10 selects the rigid-frame pillar closest to the intersection of the selected placement line and the exterior wall line as a removal target (S1007 ).

If it is determined in step S1006 that there is a rigid-frame pillar located on the outer wall line (S1006: YES), the control unit 10 determines whether the end of the corresponding rigid-frame pillar is within a predetermined distance from the nearest entry/exit corner. is determined (S1008).

In step S1008, if it is determined that the end of the corresponding rigid-frame pillar is within a predetermined distance from the entrance/exit corner (S1008: YES), the control unit 10 selects the leftmost rigid-frame pillar among the plurality of rigid-frame pillars on the target arrangement line. The (lower) Ramen pillar is selected as a removal target (S1009).

In step S1008, if it is determined that the end of the corresponding rigid-frame pillar is not within a predetermined distance from the entry/exit corner (S1008: NO), the control unit 10 selects the longest side of the outer periphery including the selected arrangement line. (S1010), and the rigid-frame pillar closest to the center of the building on the selected side is selected as a removal target (S1011).

The control unit 10 removes the rigid frame pillar selected in step S1007, S1009, or S1011 (S1012). That is, if there is a Ramen pillar that satisfies the removal conditions in step S1005, the Ramen pillar to be removed is selected from various conditions, and the selected Ramen pillar is removed.

After removing the rigid-frame pillars, the control unit 10 evaluates each placement line again (S1013), returns to step S1003, and repeats the subsequent processing.

In step S1003, if it is determined that there is no placement line with a high evaluation and the number of arranged ramen pillars is equal to or greater than the predetermined upper limit number (S1003: NO), or if in step S1005 there is no ramen pillar that satisfies the removal condition. If determined (S1005: NO), the control unit 10 ends the ramen pillar removal process without executing the subsequent processes shown as steps S1006 to S1013. Note that the processing in steps S1006 to S1013 is substantially the same as the processing in steps S807 to S814 of the eccentricity adjustment first processing described using FIG. 10.

As described above, when the number of arranged Ramen pillars is equal to or greater than the minimum number of arranged Ramen pillars, a Ramen pillar removal process is executed to remove Ramen pillars that can be further removed.

Returning to the flowchart of FIG. 3, the control unit 10 of the design support device 1 determines whether the arrangement of rigid-frame columns in all horizontal directions, that is, in both the X-axis direction and the Y-axis direction, is completed (step S11 ).

If it is determined in step S11 that the arrangement of the rigid-frame noodles pillars has been completed in all horizontal directions (step S11: YES), the control unit 10 ends the pillar arrangement process and returns to the CAD process in step S1.

If it is determined in step S11 that there is a horizontal direction in which the arrangement of the rigid-frame noodles pillars has not been completed (step S11: NO), the control unit 10 returns to step S5, and returns to step S5 for the horizontal direction in which the arrangement of the rigid-frame noodles pillars has not been completed. Execute the following processing.

In step S9, if it is determined that the number of arranged noodles is less than the minimum number of arranged noodles (step S9: NO), the control unit 10 executes a ramen pillar type change process (step S12). The rigid-frame pillar type changing process in step S12 is a process for maintaining the structural strength of the building even when the rigid-frame pillars are removed by changing the type of rigid-frame pillars.

12A and 12B are flowcharts illustrating an example of the rigid-frame pillar type changing process of the design support apparatus 1 described in the present application. The Ramen pillar type changing process executed as step S12 of the pillar arrangement process will be described. As a Ramen pillar type change process, the control unit 10 of the design support apparatus 1 resets the arrangement possible area on the arrangement line of the target floor and direction (S1201). The resetting of the placeable area in step S1201 is substantially the same as the setting of the placeable area in step S503 of the Ramen pillar temporary placement process explained using FIG. 5, but the already placed Ramen pillars are ignored. and perform the settings again.

The control unit 10 evaluates the case where the type of rigid-frame column is changed from H-shaped steel to WH-shaped steel for each arrangement line (S1202). In step S1202, when changing from H-shaped steel to WH-shaped steel, the points are scored so that when indices such as eccentricity rate and WH rate improve, the score increases, and when they worsen, the score decreases. This is the process of determining priorities. For example, if the eccentricity does not change or improves even when changing from H-section steel to WH-section steel, points will be added. On the other hand, if changing from H-section steel to WH-section steel results in a worsening of eccentricity, points will be deducted. In addition, we also provide placement lines where there is only one rigid-frame column of H-section steel, placement lines where the WH ratio or eccentricity exceeds the predetermined upper limit when changed to WH-section steel, and placement lines where the length of the placement area is less than the predetermined lower limit. If a condition such as a placement line is met, the ramen pillar on the placement line is excluded from the change target.

Based on the evaluation result, the control unit 10 determines whether or not there is a placement line where the rigid-frame noodles pillar to be converted is placed (S1203). For example, if the evaluation in step S1202 indicates that all the placement lines are excluded from the change targets, it is determined that there is no placement line on which the Ramen pillar to be changed is placed.

If it is determined in step S1203 that there is a placement line to be changed (S1203: YES), the control unit 10 determines whether or not there is a target placement line where the number of H-beam rigid-frame columns to be placed is equal to or greater than the lower limit. (S1204).

In step S1204, if it is determined that there is a target placement line whose placement number is equal to or greater than the lower limit value (S1204: YES), the control unit 10 determines that the evaluation in step S1202 is the highest among the placement lines whose number is equal to or greater than the lower limit value (S1204: YES). A placement line that is a value is selected as a conversion target (S1205).

The control unit 10 determines the presence or absence of rigid-frame columns of H-shaped steel arranged at predetermined intervals of 250 mm or the like on the selected arrangement line (S1205).

In step S1205, if it is determined that there are rigid-frame columns of H-beam steel arranged at predetermined intervals (S1205: YES), the control unit 10 integrates the rigid-frame columns arranged at predetermined intervals on the selected arrangement line. The type is changed (S1206), the process returns to step S1202, and the subsequent processes are repeated. In step S1206, two rigid-frame columns of H-shaped steel arranged at a predetermined interval of 250 mm or the like are changed to one rigid-frame column of WH-shaped steel. After changing the type of Ramen pillar, the process returns to step S1202, and the process of determining whether the type can be changed and changing the type is repeated for other Ramen pillars.

If it is determined in step S1205 that there are no rigid frame columns of H-shaped steel arranged at predetermined intervals (S1205: NO), the control unit 10 determines whether there are only two rigid frame columns on the selected arrangement line. (S1208).

If it is determined in step S1208 that there are only two Ramen pillars on the selected arrangement line (S1208: YES), the control unit 10 targets the two Ramen pillars for type change (S1209).

In step S1208, if it is determined that there are three or more Ramen pillars on the selected arrangement line (S1208: NO), the control unit 10 controls two Ramen pillars with the shortest arrangement interval among the three or more Ramen pillars. Make the pillar the target of type change.

The control unit 10 determines whether or not the two Ramen pillars targeted in step S1209 or S1210 are included in the same placement possible area (S1211).

In step S1211, if it is determined that the two targeted rigid frame columns are included in the same placement area (S1211: YES), the control unit 10 controls the left (lower) side H-shaped steel rigid frame column. The arrangement point of the column is selected as the arrangement point of the rigid-frame column of the WH section steel (S1212). In step S1212, if the two selected rigid-frame pillars are on the arrangement line in the X-axis direction, the arrangement point of the left rigid-frame pillar is selected as the arrangement point of the rigid-frame pillar after the type change. Furthermore, when the two selected rigid-frame noodles are on the arrangement line in the Y-axis direction, the arrangement point of the lower rigid-frame pillar is selected as the arrangement point of the rigid-frame pillar after the type change.

The control unit determines whether or not there is an area where the rigid-frame column of WH section steel cannot be placed within a predetermined range such as 500 mm to the right (upper) side from the placement point selected in step S1212 (S1213).

In step S1213, if it is determined that there is no area that cannot be placed within the predetermined range from the selected placement point (S1213: YES), the control unit 10 controls the It is determined whether there is a reason why placement is not possible, such as the presence of a point (S1214).

In step S1214, if it is determined that there is no reason why the arrangement cannot be done in relation to the upper and lower floors (S1214: YES), the control unit 10 integrates the two targeted Ramen pillars, changes the type, and selects the selected arrangement. The ramen pillar after the type change is arranged based on the point (S1215). In step S1206, the two rigid-frame columns of H-section steel are changed to one rigid-frame column of WH-section steel. The changed Ramen pillar is arranged based on the arrangement point selected in step S1212.

The control unit 10 determines whether the rigid frame column of the WH section steel after the type change falls within the arrangement possible area (S1216).

If it is determined in step S1216 that the type-changed ramen pillar is not within the placement possible area (S1216: NO), the control unit 10 adjusts the placement position of the ramen pillar (S1217), and returns to step S1202. , repeat the subsequent processing. In step S1217, the placement point of the Ramen pillar that does not fall within the placement area is adjusted to a position shifted by 500 mm from the right (top) end of the placement area to the left (bottom).

In step S1216, if it is determined that the type-changed ramen pillar is within the placement possible area (S1216: YES), the control unit 10 does not perform the process of step S1217, and moves it to the position placed in step S1215. It is fixed, the process returns to step S1202, and the subsequent processing is repeated.

In step S1211, if it is determined that the two targeted Ramen pillars are not included in the arrangement possible area at the same position (S1211: NO), the control unit 10 controls the arrangement of the left (lower) Ramen pillar. It is determined whether the possible area is longer than a predetermined length such as 500 mm (S1218).

In step S1218, if it is determined that the arrangeable area is longer than or equal to the predetermined length (S1218: YES), the control unit 10 proceeds to step S1212 and executes subsequent processing.

In step S1218, if it is determined that the arrangeable area is less than the predetermined length (S1218: NO), the control unit 10 determines whether the arrangeable area of the right (upper) side rigid-frame noodles column is equal to or larger than a predetermined length such as 500 mm. It is determined whether or not (S1219).

In step S1219, if it is determined that the arrangement possible area is equal to or greater than the predetermined length (S1219: YES), the control unit 10 changes the arrangement point of the right (upper) side H-shaped steel rigid-frame column to the WH-shaped steel rigid-frame column. (S1220).

The control unit determines whether or not there is an area in which a rigid frame column of WH section steel cannot be placed within a predetermined range such as 500 mm to the right (upper) side from the placement point selected in step S1220 (S1221).

In step S1221, if it is determined that there is no area that cannot be placed within the predetermined range from the selected placement point (S1221: YES), the control unit 10 controls the It is determined whether there is a reason why placement is not possible, such as the presence of a point (S1222).

In step S1222, if it is determined that there is no reason why placement is impossible based on the relationship between the upper and lower floors (S1222: YES), the control unit 10 proceeds to step S1215, integrates the two targeted Ramen pillars, and changes the type. Then, based on the selected placement point, the process of placing the ramen pillar after the type change and the subsequent processes are executed.

If it is determined in step S1213 that there is an area where placement is not possible within a predetermined range from the selected placement point (S1213: NO), or if it is determined in step S1214 that there is a reason why placement is not possible due to the relationship between the upper and lower floors (S1214 :NO), the control unit 10 proceeds to step S1219 and executes the subsequent processing. That is, if it is impossible to arrange the Ramen pillar after the type has been changed, the placement conditions are changed to examine whether the type can be changed.

If it is determined in step S1219 that the placeable area is less than the predetermined length (S1219: NO), or if it is determined in step S1221 that there is an unplaceable area within the predetermined range from the selected placement point (S1221: NO) Or, in step S1222, if it is determined that there is a reason why placement is not possible due to the relationship between the upper and lower floors (S1222: NO), the control unit 10 determines whether there is a set of unprocessed Ramen pillars (S1223). That is, if it is impossible to arrange the Ramen pillar after changing the type, it is considered whether or not to change the type of other Ramen pillars.

If it is determined in step S1223 that there is a set of unprocessed ramen pillars (S1223: YES), the control unit 10 returns to step 1208 and repeats the subsequent processing.

If it is determined in step S1223 that there is no set of unprocessed ramen pillars (S1223: NO), the control unit 10 returns to step S1202 and repeats the subsequent processing.

If it is determined in step S1203 that there is no placement line to be changed (S1203: NO), or if it is determined in step S1204 that there is no target placement line with the number of placements equal to or greater than the lower limit (S1204: YES), the control The unit 10 ends the ramen pillar type changing process without executing the processes after step S1205.

As described above, the rigid-frame column type changing process is executed to change the type of two H-shaped steel rigid-frame columns by merging them into one WH-shaped steel rigid-frame column.

Returning to the flowchart of FIG. 3, the control unit 10 of the design support apparatus 1 determines whether the number of arranged pieces is equal to or greater than the minimum number of pieces arranged (step S13).

In step S13, if it is determined that the number of Ramen pillars to be arranged is equal to or greater than the minimum number of Ramen pillars to be arranged (Step S13: YES), the control unit 10 proceeds to Step S11, and determines whether the arrangement of all the horizontal Ramen pillars has been completed. Determination is made (step S11).

If it is determined in step S13 that the number of noodles to be placed is less than the minimum number of noodles to be placed (step S13: NO), the control unit 10 executes additional ramen pillar placement processing (step S14). The ramen pillar addition process in step S14 is a process for adding ramen pillars when the number of ramen pillars to be arranged is less than the minimum number due to the processes up to that point.

FIG. 13 is a flowchart illustrating an example of the rigid-frame pillar addition arrangement process of the design support apparatus 1 described in the present application. The additional Ramen pillar placement process executed as step S14 of the pillar placement process will be described. As the rigid-frame column addition arrangement process, the control unit 10 of the design support device 1 resets the arrangement possible area for the load-bearing element line on which the rigid-frame column of H-section steel or WH-section steel is arranged (S1401).

The control unit 10 acquires the range in which the degree of structural success that satisfies the preset conditions is reduced due to the placement of the H-beam rigid-frame column in the re-set arrangement possible region (S1402), and determines the range in which the degree of structural success that satisfies the preset conditions is reduced. The range in which the probability of establishment decreases is excluded from the placement possible area (S1403). For example, a range of 500 mm from both ends of rigid-frame columns made of H-shaped steel arranged at 250 mm intervals, a range of 500 mm from both ends of rigid-frame columns made of WH-shaped steel, and a range of 750 mm from both ends of rigid-frame columns made of H-shaped steel. The range, such as the range where there is an end of another rigid frame pillar within, is set as a condition where the degree of structural success is reduced.

The control unit 10 excludes a placement line in which no placeable area exists from among the placement lines (S1404). The control unit 10 derives the eccentricity when additionally arranging the rigid frame columns of H-section steel (S1405), and determines whether there is a placement line where the eccentricity decreases due to the additional arrangement (S1406). In step S1405, a situation in which one additional rigid frame pillar is placed in the placement possible area is simulated, and the eccentricity at the time of additional placement is derived. In step S1406, the eccentricity before and after the addition is compared based on the simulation results, and it is determined whether there is a placement line where the eccentricity improves (decreases in numerical value) due to the addition of the rigid frame column.

In step S1406, if it is determined that there is a placement line where the eccentricity is reduced by additional placement (S1406: YES), the control unit 10 places a rigid-frame column of H-shaped steel within the placement possible area (S1407). In step S1407, the eccentricity before and after the addition of the rigid frame column is compared, and the H-shaped steel is placed at the leftmost (lower) position of the placement line for the placement line where the eccentricity is the best (the width of the decrease in numerical value is the largest). Place the ramen pillar. If there are multiple placement lines with the largest decrease in eccentricity, the leftmost (lower) placement line is the target for placement of the rigid-frame pillars.

After arranging the rigid-frame columns of H-section steel, the control unit 10 determines whether the number of additionally arranged rigid-frame columns is equal to or greater than the minimum number of columns to be arranged in step S1407 (S1408).

If it is determined in step S1408 that the number is less than the minimum number of lines to be placed (S1408: NO), the control unit 10 resets the placement possible area of the target placement line (S1409), returns to step S1404, and repeats the subsequent processing. .

In step S1406, if it is determined that there is no placement line for which the eccentricity decreases due to the additional placement (S1406: NO), the control unit 10 determines that the eccentricity after the additional placement is a preset upper limit such as 15%. The presence or absence of the following arrangement lines is determined (S1410). In step S1410, if there are multiple applicable placement lines, the placement line with the highest eccentricity (lowest eccentricity) is selected, and if there are multiple placement lines with the lowest eccentricity, the leftmost (lower) side Select a placement line.

In step S1410, if it is determined that there is a placement line whose eccentricity after additional placement is less than or equal to the upper limit value (S1410: YES), the control unit 10 proceeds to step S1407 and executes the subsequent processing. In the process of step S1407, if there are a plurality of applicable placement lines in step S1410, the placement lines that meet the above-mentioned conditions are selected as processing targets.

If it is determined in step S1408 that the number of arranged lines is less than the minimum number of arranged lines (S1408: YES), or if it is determined in step S1410 that there is no arranged line whose eccentricity is less than the upper limit after additional arrangement (S1410: NO), The control unit 10 ends the Ramen pillar addition arrangement process.

As described above, the Ramen pillar addition arrangement process is executed.

Returning to the flowchart of step S3, after the rigid-frame pillar addition process, the control unit 10 of the design support device 1 proceeds to step S11, and determines whether or not the arrangement of all horizontal rigid-frame pillars has been completed (step S11). .

If it is determined in step S7 that the number of arranged pieces is less than the minimum number of pieces arranged (step S7: NO), the control unit 10 of the design support apparatus 1 executes the second eccentricity adjustment process (step S15). The second eccentricity adjustment process in Step S15 means that if the number of Ramen pillars exceeding the minimum number of Ramen pillars is not placed in the Temporary Ramen pillar placement process in Step S5, the minimum number of Ramen pillars is adjusted in the structural index adjustment process in Step S6. The lower the number, the more the process is performed when the rigid frame pillar is removed.

FIG. 14 is a flowchart illustrating an example of the second eccentricity adjustment process of the design support apparatus 1 described in the present application. The second eccentricity adjustment process executed as step S15 of the column arrangement process will be described. In the second eccentricity adjustment process, the temporary rigid-frame column placement process and the structural index adjustment process are performed again on the placement line that satisfies a predetermined condition to increase the number of rigid-frame columns to be arranged.

As the second eccentricity adjustment process, the control unit 10 of the design support apparatus 1 refers to the relocation index derivation table recorded in the structure information database 113 and derives a relocation index for each layout line (S1501). When re-arranging the Ramen pillar as a temporary arrangement again, the re-arrangement is a numerical value that is an index of the effect of the re-arrangement, assuming that the Ram-en pillar is re-arranged with respect to the placement line that is the target of the re-arrangement. Indicators are used. In step S1501, a relocation index is derived based on a relocation index derivation table exemplified in Table 7 below. The relocation index derivation table is recorded in the structure information database 113, and when deriving the relocation index, the control unit 10 accesses the structure information database 113 and refers to the recorded contents. In addition, when deriving the relocation index, the number is calculated based on the rigid-frame columns of H-shaped steel, so one rigid-frame column of WH-shaped steel is converted to 2.5 rigid-frame columns of H-shaped steel. do.

Based on the derived relocation index, the control unit 10 determines whether there is a placement line that satisfies preset relocation conditions for relocating the rigid-frame noodles (S1502). In step S1502, a placement line whose derived relocation index is 0 or more becomes a placement line that satisfies the relocation condition.

If it is determined in step S1502 that there is a placement line that satisfies the relocation condition (S1502: YES), the control unit 10 selects a placement line to be relocated from among the placement lines that satisfy the relocation condition. (S1503). In step S1503, the placement line with the highest relocation index is selected as a relocation target.

The control unit 10 arranges the rigid frame columns of H-beam steel to the maximum number within the arrangement possible area set on the selected arrangement line (S1504). The process related to the placement of the Ramen pillars in step S1504 is substantially the same as the process exemplified as the temporary Ramen pillar placement process described above, so the detailed explanation will be omitted with reference to the description of the Temporary Ramen pillar placement process.

The control unit 10 determines whether there is an arrangement possible area in which three or more rigid-frame columns of H-shaped steel are arranged (S1505).

In step S1505, if it is determined that there is an arrangement possible area in which three or more H-shaped steel rigid-frame columns are arranged (S1505: YES), the control unit 10 controls the The pillars are integrated and the type is changed (S1506). In step S1506, two rigid-frame columns of H-section steel arranged at a predetermined interval of 250 mm or the like are changed to one rigid-frame column of WH-section steel. For the rigid-frame columns within the placement area set on the placement line in the X-axis direction, the two H-shaped steel rigid-frame columns located on the left side are targeted, and the left end of the leftmost rigid-frame column is placed. As a point, it is integrated into one rigid frame column of WH section steel. For rigid-frame columns within the placement area set on the placement line in the Y-axis direction, the two H-shaped steel rigid-frame columns located at the lower end are targeted, and the left end of the lowest rigid-frame column is As a placement point, it is integrated into one rigid frame column of WH section steel.

The control unit 10 determines whether or not three or more rigid-frame columns of H-beam steel are still consecutively arranged within the arrangement possible area where the rigid-frame columns whose type has been changed are arranged (S1507). In step S1507, the arrangement of continuous Ramen pillars indicates that the Ramen pillars are arranged at intervals of a predetermined length, such as 250 mm, within the same arrangement area. Even if they are in the same arrangement area, if they are separated by more than a predetermined length, they are considered not to be continuous.

In step S1507, if it is determined that three or more are consecutively arranged (S1507: YES), the control unit 10 returns to step S1506 and repeats the subsequent processing.

In step S1507, if it is determined that there are no rigid frame columns in which three or more are consecutively arranged (S1507: NO), the control unit 10 sets the eccentricity of the target arrangement line to a predetermined value such as 15% or less. It is determined whether the eccentricity condition is satisfied (S1508).

If it is determined in step S1507 that the eccentricity condition is not satisfied (S1508: NO), the process returns to step S1501 and the subsequent processes are repeated.

If it is determined in step S1502 that there is no placement line that satisfies the relocation conditions (S1502: NO), or if it is determined in step S1505 that there is no placement possible area where three or more H-beam rigid frame columns are placed. (S1505: NO), or if it is determined in step S1507 that the eccentricity condition is satisfied (S1507: YES), the control unit 10 ends the second eccentricity adjustment process.

The processes of steps S1505 to S1507 in the second eccentricity adjustment process will be specifically described. FIG. 15 is an explanatory diagram schematically showing an overview of a part of the second eccentricity adjustment process executed by the design support apparatus 1 described in the present application. FIG. 15 schematically shows an example in which two placement possible areas are set on the placement line to be processed. In FIG. 15, broken lines indicate placement lines, and thin rectangles indicate placement possible areas. In addition, the thick lines indicate the type of rigid-frame pillars arranged according to their cross-sectional shapes. As shown in FIG. 15(a), three rigid-frame columns made of H-shaped steel are arranged in each of the two arrangement possible areas. First, the left arrangable area is targeted for processing, and as shown in FIG. 15(b), the type of the leftmost rigid frame column is changed to WH section steel, and the second rigid frame column from the left is The pillar has been removed. As shown in FIGS. 15(a) and 15(b), the rigid-frame column type changing process is a process in which the rigid-frame columns are integrated and the type is changed from H-shaped steel to WH-shaped steel. Note that after the process in step S1506, the process returns to step S1501, so the same process is performed on the rigid frame pillar in the placement possible area on the right side.

FIG. 16 is an explanatory diagram schematically showing an outline of the rigid-frame pillar type changing process executed by the design support apparatus 1 described in the present application. FIG. 16 is an explanatory diagram schematically showing an overview of a part of the second eccentricity adjustment process executed by the design support apparatus 1 described in the present application. As shown in FIG. 16(a), six rigid-frame columns made of H-shaped steel are arranged in the arrangement possible area. Through the process of step S1506, as shown in FIG. 16(b), the type of the leftmost rigid-frame pillar is changed to WH section steel, and the second rigid-frame pillar from the left is removed. In addition, at the stage of FIG. 16(b), since four rigid-frame columns of H-beam steel are arranged within the arrangement possible area, the process of step S1506 is executed again based on the determination result of step S1507. , and the same process is performed for the remaining four lines. FIG. 16(c) shows a state in which the process in step S1506 has been further performed from the state shown in FIG. 16(b), in which there are two rigid-frame columns of WH-shaped steel, and There are two pillars. As shown in FIG. 16(c), the number of rigid-frame columns of H-shaped steel is less than three, so based on the determination result in step S1507, changing the type of rigid-frame columns for the arrangement possible area is finished.

As described above, the second eccentricity adjustment process is executed.

Returning to the flowchart of FIG. 3, the control unit 10 of the design support apparatus 1 determines whether the number of arranged pieces is equal to or greater than the minimum number of pieces arranged (step S16).

If it is determined in step S16 that the number of Ramen pillars to be arranged is equal to or greater than the minimum number of pillars to be arranged (Step S16: YES), the control unit 10 proceeds to Step S11, and determines whether or not the arrangement of the Ramen pillars in all directions has been completed. (Step S11).

If it is determined in step S16 that the number of arranged noodles is less than the minimum number of arranged noodles (step S16: NO), the control unit 10 proceeds to step S12 and executes a Ramen pillar type changing process (step S12).

The pillar arrangement process is executed as described above.

As described above, the design support apparatus 1 described in the present application temporarily arranges columns at positions where columns can be arranged so that the number of columns to be arranged is maximized, and then removes removable columns. In addition, when removing columns, we quantify the arrangement of rigid-frame columns and derive structural indicators and indicators such as eccentricity that indicate the structural condition such as the strength of the building. Determine the pillars to be removed according to the following. Additionally, in order to prevent a decrease in strength, the type of rigid frame columns to be placed will be changed from H-shaped steel to WH-shaped steel. Therefore, when designing a building, it is possible to automatically place columns necessary for the building at positions that take structural strength into consideration. Furthermore, even those in charge of designing buildings can easily design with structural strength in mind, and can also simplify the work of arranging columns and improve work efficiency. be.
