FIG. 3 is a flowchart showing a main flow of determining the arrangement of the load-bearing walls by the wall arrangement design system of the present embodiment.

In the wall layout design system of this embodiment, first, building information relating to the outline, layout, and position of the opening of the building is input (step A), and based on the input building information, the building information is obtained. A wall forming portion capable of forming (arranging) a bearing wall is detected (step B), and all the detected wall forming portions have the maximum strength according to the specification of the building and the position of each wall forming portion. The load-bearing walls are arranged (Step C), and it is determined whether or not the total wall amount of the plurality of placed load-bearing walls satisfies a predetermined required wall amount (Step D), and the eccentricity of the building on which the load-bearing walls are arranged is determined. When the calculated eccentricity exceeds a predetermined value, a part of the plurality of load-bearing walls arranged by the load-bearing wall arranging means is replaced with a wall having a smaller strength. The eccentricity is equal to or less than the predetermined value. Adjusted (step E), it is displayed as a result of the arrangement of the bearing walls after eccentricity adjustment (step F).

The input of building information (step A) is performed, for example, by displaying an instruction for requesting input on a display device and operating the input device in accordance with the instruction. As building information, in addition to the outline of the building, the layout and the position of the opening,
The user inputs information on the roof, information on sleeve walls, balconies, bay windows, dormers, etc. which affect the found area.
For the information on the external shape and the floor plan of the building, information for each floor is input.

As information on the outline of the building, the number of floors of the building, the outline of each floor, and the like are input. In addition, as information on the floor plan, each room (space) arranged in a building such as a Japanese-style room, a living room, a dining room, a kitchen, a bath, a toilet, and a staircase.
Enter the size and arrangement of these. Further, as the information on the position of the opening, the position, size, and the like of the opening, such as a window, a doorway, a ventilation fan, and storage in the wall, which affect the arrangement of the load-bearing wall, are input.

When the building information is input, rooms such as a Japanese-style room, a living room, a dining room, etc. are allocated to each floor of the building based on the building information, and at the same time, a necessary wall space between the inside and outside of the building or between the rooms is provided. The position and length are determined. Further, the position and size of each opening provided in the building are determined. And, among the walls formed between the inside and outside of the building and between each room,
A portion (location) forming a wall having a length equal to or longer than a predetermined value (for example, three shakus) and having no opening is detected as a wall forming portion forming a bearing wall (step B).

Next, bearing walls are arranged on all the detected wall forming portions so as to have the maximum strength in accordance with the specification of the building and the position of each wall forming portion (step C). Specifically, for each of the wall forming portions, it is determined which of the outer peripheral wall and the partition wall is to be formed, and what kind of room is to form the wall surrounding the room. In accordance with the determination result and the specification of the building input as the building information, for each wall forming portion, a load-bearing wall having the maximum load-bearing capacity is retrieved from the database stored in the auxiliary storage device 2 and selected. You. Then, the selected load-bearing wall is arranged at each wall forming portion.

Table 1 summarizes a part of the information on the load-bearing walls stored in the auxiliary storage device 2 as a database. Table 1 shows, for each of the building specifications (A specification to D specification), The basic configuration of a bearing wall arranged as an outer peripheral wall and the basic configuration of a bearing wall arranged as a partition wall are shown. Here, the “basic configuration” is a configuration of a load-bearing wall determined by the specification of the building and whether it is a load-bearing wall that forms the outer peripheral wall or the partition wall, and any room such as a Japanese-style room, a living room, and a bathroom. Is determined without considering whether or not to form a wall surrounding the wall.

[0029]

[Table 1]

More specifically, the column of the outer peripheral wall in Table 1 shows the basic configuration of the bearing wall arranged as the outer peripheral wall. For example, the bearing wall arranged as the outer peripheral wall of the A-spec building is shown. Is the outer wall surface material with a wall magnification of 2.5 times and a wall magnification of 2.0
It shows that the configuration consisting of double bracing is the basic configuration. Further, the column of the partition wall in Table 1 shows a basic configuration of the load-bearing wall arranged as the partition wall. For example, the load-bearing wall arranged as the partition wall of the A-spec building has a wall magnification of 4.0. It shows that the configuration consisting of double braces is the basic configuration. In Table 1, the value 0.0 in the column of the outer wall bracing or the inner wall bracing indicates that the brace is not included in the basic configuration, and 2.0 indicates that one brace having a wall magnification of 2 is included in the basic configuration. .0 indicates that there are two brace with a wall magnification of 2 in the basic configuration.

The load-bearing walls arranged in the respective wall forming portions are not the walls of the basic structure determined by the specifications of the building and the distinction between the load-bearing walls forming the outer peripheral wall and the partition wall as described above. Considering the necessary conditions depending on what kind of room is to be placed on the wall surrounding the room, such as a Japanese room, living room, bathroom, etc. The wall determined above. That is, when the position of the wall forming portion is a position that does not limit the disposition of the load-bearing wall of the basic configuration in Table 1, the load-bearing wall of the basic configuration is disposed, and the position of the wall forming portion is If it is a position where it is not allowed to dispose the load-bearing wall of the basic structure shown in Table 1, one or two of the face material and the brace will be used instead of the load-bearing wall of the basic structure shown in Table 1. A bearing wall having a configuration other than the above is disposed.

As shown in Table 1, in the wall layout design system of the present embodiment, a single or two load-bearing surface materials are used as load-bearing walls having the maximum load resistance for each of the wall forming portions. A bearing wall consisting of a single or two braces, or a bearing wall consisting of a single or two bearing surfaces and a single or two braces. ing.

FIG. 4 is a diagram showing a state in which a load-bearing wall having the maximum strength according to the specifications of the building and the position of each wall-forming portion is arranged on each wall-forming portion of the first floor in a specific building. It is. FIG. 4 is a diagram showing the first floor of the building of the D specification in Table 1 above, and FIG. 5 shows the first floor of the same building before the load-bearing walls are arranged.

In FIG. 4, S denotes a bearing wall composed of one brace (wall magnification: 2 times), and D denotes a bearing wall composed of two braces (wall magnification: 4 times). Note that the arrangement of the load-bearing walls shown in FIG. 4 is displayed on the screen of the display device 4 together with grid lines (not shown) set in a grid pattern. The center line is located on the grid line and along the grid line.

After the bearing walls having the maximum strength corresponding to the specifications of the building and the position of each wall forming portion are arranged on each wall forming portion in this manner, a plurality of the arranged bearing walls are arranged. It is determined whether the total wall amount satisfies a predetermined necessary wall amount (step D). The determination as to whether or not the necessary wall amount is satisfied in step D is made in order to design a building having a sufficient proof strength. In the wall layout design system of the present embodiment, for example, a flow as shown in FIG. A check of the amount of wall is performed.

An example of the procedure for checking the amount of wall will be described with reference to FIG. First, for each type of load-bearing wall, the total length of the wall is multiplied by the wall magnification determined for each type to calculate the wall amount,
Further, these wall amounts calculated for each type are summed to calculate a total wall amount (step D1). The total wall amount is calculated for each floor of the building. Next, the required wall amount for the seismic force and the required wall amount for the wind pressure are calculated for each floor (step D2).

The required wall amount for the seismic force is calculated by multiplying the floor area of each floor by a wall amount coefficient for each floor which is preset according to the weight of the roof and the like. The above wall coefficient depends on whether the building is a one-story, two-story or three-story building, how many floors of the building, whether it is a heavy roof design or a light roof design, whether it is a snowy area specification, etc. The data of the coefficient is stored in the auxiliary storage device 2 in the arithmetic processing device 1.
Is stored as data necessary for a program for functioning as the wall amount inspection means.

The required wall amount with respect to the wind pressure is calculated, for example, by multiplying the found area by a coefficient (for example, 0.5) preset according to the wind pressure. The margin P set for each building specification is set to the larger of the required wall amount for the calculated seismic force and the required wall amount for the wind pressure (P is 1).
(See Table 1 above) to obtain a wall amount for determination (step D3).

Then, it is determined for each floor whether or not the total wall amount of the arranged load-bearing walls exceeds the wall amount for determination (step D4), and for all floors, the total wall amount is determined. If the amount is satisfied, it is determined that both the earthquake resistance and the wind resistance are sufficient. On the other hand, on any floor,
When the total wall amount is less than the wall amount for determination, it is determined that the required wall amount is not sufficient, and the display device 4 is instructed to that effect or a correction instruction such as a layout or a position of an opening. It is displayed as an error display (step D5).

The total wall amount and the judgment wall amount are determined by dividing the wall of the building into an X-direction wall along a horizontal grid line and a Y-direction wall along a vertical grid line. It is calculated separately for each of the wall in the direction and the wall in the Y direction. Also, determination whether the total wall amount of the load-bearing walls satisfies the wall amount for determination is performed for each of the X-direction wall and the Y-direction wall.
When both the X-direction wall and the Y-direction wall satisfy the predetermined determination wall amount, it is determined that both the anti-seismic and the anti-wind walls are sufficient.

The adjustment of the eccentricity in step E is performed in order to design a building having a well-balanced structural strength. In the wall layout design system according to the present embodiment, for example, as shown in FIG. The eccentricity is adjusted by the flow.

An example of the procedure for adjusting the eccentricity will be described with reference to FIG. First, as described above, the eccentricity of each floor is calculated for each of the floors in which the load-bearing walls are arranged on all the wall forming portions (step E1), and the calculated eccentricity of each floor is a predetermined value (preferably, 0. 1). 15) It is determined whether or not it is below (step E2). If the eccentricity exceeds one of the predetermined values for any one of the floors, it is determined that the structural balance of the building is inadequate, and for the floor whose eccentricity exceeds the predetermined value, the correction of the eccentricity by replacing the bearing wall is performed. Perform (Step E3). Then, for the arrangement after the replacement, the wall amount is checked in exactly the same procedure as in the wall amount check in step D, and the eccentricity is calculated again and the eccentricity is checked again for the arrangement after the bearing wall replacement. . If the eccentricity in the arrangement after the replacement of the bearing wall still exceeds the predetermined value, one or more of the remaining bearing walls that were not replaced at the time of the first replacement are replaced with walls having smaller bearing strength. In this manner, the replacement of the load-bearing wall, the check of the wall amount, the calculation of the eccentricity, and the check of the eccentricity are repeated until the eccentricity becomes equal to or less than the predetermined value. In the process of adjusting the eccentricity, if the total wall amount of the load-bearing walls falls below a predetermined necessary wall amount as in step D, the adjustment is stopped, and as in step D, the adjustment is stopped. And an instruction to correct the layout or the position of the opening is displayed as an error display.

Hereinafter, the adjustment of the eccentricity of step E will be described in more detail. In the calculation of the eccentricity (step E1), the center of gravity, the rigidity, and the radius of elasticity of each floor of the building are obtained, and the distance (eccentric distance) between the center of gravity and the rigidity is divided by the radius of elasticity. The eccentricity is calculated for each of the X direction along the horizontal grid lines and the Y direction along the vertical grid lines. In the arrangement of the load-bearing walls shown in FIG. 4, the center of gravity is located at the position indicated by a symbol in which ○ and X are superimposed,
It is in the position shown by the mark. And in the arrangement of FIG.
The eccentricity in the X direction is 0.32 and the eccentricity in the Y direction is 0.26
It is.

The above-described replacement of each load-bearing wall is replaced with a wall having a configuration excluding at least one of the load-bearing surface material and the brace constituting each load-bearing wall. The load-bearing wall is replaced with a wall with a smaller strength in order from the load-bearing wall located farthest away from the building's center of gravity, as viewed from the building's center of gravity, so that the building's center of gravity approaches the building's center of gravity. Replace. More specifically, when the rigidity is moved closer to the X direction, the load-bearing walls arranged along the Y direction are sequentially replaced by walls having smaller strengths, and when the rigidity is moved closer to the Y direction, The load-bearing walls arranged along the X direction are sequentially replaced with walls having smaller load-bearing strength. Such replacement of the bearing wall is performed until both the eccentricity in the X direction and the eccentricity in the Y direction become equal to or less than a predetermined value. When the eccentricity in the X direction and the eccentricity in the Y direction are equal to or less than the above-mentioned predetermined values for all floors, the eccentricity for each floor and each of the X and Y directions is displayed on the display device 4 ( Step E5).

FIG. 8 shows the result of the adjustment of the eccentricity. The position of the rigid center indicated by * in FIG.
As a result, the eccentricity in the X direction is adjusted to 0.07 and the eccentricity in the Y direction is adjusted to 0.12. After the adjustment of the eccentricity is completed for all floors, the arrangement of the load-bearing walls of each floor after the eccentricity adjustment is displayed on the display device 4 (step F). In addition, about a certain floor,
If the eccentricity is already less than or equal to the predetermined value in a state where the load-bearing walls are arranged on all the wall forming portions, the eccentricity is not adjusted for that floor, and the placement of the load-bearing wall is not changed for that floor as a result. indicate.

As described above, according to the wall layout design system of the present embodiment, based on the building information such as the floor plan of the building, the strength of the building is sufficient and the balance in the structural strength of the building is improved. The arrangement of the load-bearing walls can be quickly determined.

Therefore, even a person having little knowledge of the structural design can know at an early stage whether or not he / she can listen to the customer's request regarding the floor plan and the position of the opening. Swift response is possible. In addition, if it is found that the strength of the building is insufficient or that the balance of the structural strength of the building is inadequate if the customer's request is completely reflected, the floor plan and the position of the opening etc. should be changed at an early stage. Can be suggested to customers. Particularly, it is extremely advantageous from the viewpoint of maintaining trust from customers that it is possible to avoid the necessity of changing the layout after deciding the layout by discussion with the customer. Also, before starting the implementation design, it is possible to quickly determine the arrangement of the load-bearing walls so that the strength of the building is sufficient and the structural strength of the building is well balanced, so that rework work can be avoided. Thus, the burden of designing such a building can be reduced.

Further, the bearing wall arranging means treats each of the wall forming portions as three layers, and for each of the wall forming portions, as the bearing wall, a bearing wall made of a single or two load bearing surface members, a single wall. Or, a load-bearing wall composed of two braces, or a load-bearing wall composed of a single or two load-bearing surface materials and a single or two braces, and the eccentricity adjusting means is
The eccentricity is adjusted by replacing the load-bearing wall disposed by the load-bearing wall arranging means with a wall having a configuration excluding at least one of the load-bearing surface material and the brace constituting the load-bearing wall. As a result, fine adjustment of the eccentricity and highly accurate adjustment are possible.

Further, since the wall quantity inspection means judges whether or not both the necessary wall quantity for the seismic force and the required wall quantity for the wind pressure are satisfied, both the eccentricity and the proof stress are determined. Excellent building can be designed.

The preferred embodiments of the wall layout design system and the recording medium according to the present invention have been described above. However, the wall layout design system and the recording medium according to the present invention are not limited to the above-described embodiments, and the spirit of the present invention. Can be appropriately changed without departing from the range. For example, the order of replacement of the load-bearing walls in the eccentricity adjusting means is not particularly limited as long as the eccentricity can be adjusted to a predetermined value or less, and the eccentricity in any one of the eccentricity in the X direction and the eccentricity in the Y direction is not limited. After reducing the rate to within a predetermined value, the eccentricity in the other direction may be reduced to within a predetermined value, or the eccentricity in the X direction and the Y direction may be simultaneously reduced to within a predetermined value. .
