[Problems to be Solved by the Invention] When designing a building structure, after creating a block plan, the detailed design is carried out based on this block plan. In the case, the owner makes a design change, and depending on the content, it is often necessary to redo the structural design of the building structure based on the block plan. In this way, it takes a lot of time and effort to redo the block plan and the structural design of the frame, which causes inconvenience in the business plan,
In many cases, the owner's wish cannot be answered. Generally, the designer of the block plan and the designer of the building frame are different people, and there are contacts between the two, but due to human error, there is inconsistency between them, and the construction work is added. Although it is designed, depending on the skill level of the designer, the design may be significantly changed on site, which may further delay the business plan. recently,
Standards have been standardized for the members that make up the building, but there are few standardized construction methods, and it is therefore necessary to have a skilled construction technician in the field. The number is decreasing, and securing it is becoming difficult.

The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to automatically create a block plan and design a building frame based on it, thereby significantly reducing the time and labor in the planning stage, and Changes can be dealt with easily and quickly, and inconsistencies can be eliminated in the exchange of information between the block plan and the building frame and the exchange of information between designers, builders, and factory producers. Furthermore, it aims to provide a structural design system for a building frame by standardizing the construction method as much as possible so that even a multi-skilled worker who is not skilled can carry out construction.

FIG. 2 is a flow chart showing sequential steps in the structural design system for a building frame according to the present invention. First, in step S1, a block library is read from the storage means 1 to the processing means 2 in order to determine a block plan, and subsequently in step S2, a basic plane outline defining the plane contour of the entire building frame is input via the input means 3. Enter basic parameters such as shape, frame type such as open corridor type, middle corridor type, staircase type, and number of spans.
The block plan library has a large number of block plans created in advance. Figure 3 shows the individual block plans.
As shown in, it has the frame type, the number of spans, and the number of wild gooses as parameters. Here, there are three basic types of frame type: open corridor type, middle corridor type, and staircase type.
Most apartments fall into one of these forms. In addition, the number of geese is the basic plane outline shape, and the number of geese is 0 without steps as shown in FIG. 3A, and the basic plane outline represents a rectangular building. No. 2 represents a building having a step at two places as shown in FIG. 3B. The number of spans represents the number of units arranged in a row in an apartment house.
A block plan for a building with a span number of 12 is registered. Further, in FIG. 3, the circles lined up in the vertical direction are mere standards of dimensions, and do not indicate the positions of the columns.

Next, in step S3, the input means 3
The block plan selection system 2a of the processing means 2 is activated according to the basic parameters input via the, and the block plan automatic selection program is executed. That is, a block plan that matches the input basic parameter is automatically selected from the block plan library that is registered in advance. In this case, a plurality of block plans may be selected, in which case the operator further makes a judgment and selects and sets a desired block plan.
For this purpose, the arbitrary block plan can be displayed on the display means 4 via the input means 3.

Next, in step S4, the total number of floors and the structure type are input through the input means 3, and the floor height setting system 2
Start b and set the height of each floor automatically. That is, in step S5, the processing means 2 reads the standard floor height library stored in advance in the storage means 1. From the read standard floor height library, the one that matches the input total floor number and structure type is automatically selected, and the floor height of each floor is automatically set (step S
6). In this way, a wire frame representing the frame structure of the entire building can be created. 4A and 4B show the contents of the standard floor height library,
A represents 2760 mm and B represents 2860 mm. Standard floor height library is RC (reinforced concrete)
Since the structure and the SRC (steel-framed reinforced concrete) structure are prepared for each structure type, the structure type and the total number of floors input via the input means 3 can be automatically set as parameters. For example, in the case of an 8-story apartment house with an SRC structure, the height of the first and second floors is 2860.
mm, the height of the 3rd to 8th floors is automatically set to 2760 mm.

After selecting and setting a desired block plan and setting the floor height of each floor as described above, the length and depth of the unit span are set via the input means 3 in step S7. .. When the dimensions are set in this way, the processing means 2 executes the core setting program to automatically determine the core, and further performs centering with the thus determined core as a reference, and the column position and the beam. The position and the like are automatically determined (step S8).

As described above, after the block plan is determined, the total number of floors, the floor height of each floor are set, and the span length and the depth dimension are set, next, 1 for setting the cross-sectional structure of the structural frame is set. The next member setting system 2c is activated. In order to execute this cross-section structure setting program, it is necessary to further specify the construction method types such as the PC construction method, the half PC construction method, the large formwork construction method, the pre-assembled rebar construction method, etc. Therefore, the construction method type is input via the input means 3. Yes (step S9). In the storage means 1, as shown in FIGS. 5 and 6, a standard column cross-section library in which standard cross-section dimensions of columns are specified for each structure type, and as shown in FIG. 7, the structure of columns for each standard cross-section dimension is constructed. A column structure library for each type, a beam standard cross-section library for designating the standard cross-sectional dimensions of each beam as shown in FIGS. 8 and 9, and a beam of each standard size as shown in FIG. A beam structure library that specifies the structure for each construction method, a beam cross-section library that shows the beam cross-sectional dimensions using the structure type and construction method type as parameters as shown in FIG. 11, and seismic resistance for each inner wall and outer wall as shown in FIG. The earthquake resistant wall library representing the structure of the wall is stored in advance, and these libraries are read and set in step S10. 7 and 10, Fc represents concrete design standard strength, and SD represents reinforcing bar strength. Further, the first number of the number of main bars represents the number of bars, and the subsequent number represents the diameter of the reinforcing bar, for example, 4-D22.
Indicates that four deformed rebars having a diameter of 22 mm are used. Furthermore, 2-D10-200 @ represents a shear reinforcing bar, and the first number represents the number of points where a horizontal line or a vertical line passing through the center intersects with the reinforcing bar in a cross section orthogonal to the main bar. The symbol represents the type and diameter of the reinforcing bar, and the last number represents the pitch.
Therefore, in the above example, 2
It indicates that the main bars are arranged at a pitch of 00 mm. In executing the primary member setting program 2c, these libraries are first read from the storage means 1 to the processing means 2.

As a basic rule for setting the column section, all columns are basically the same section for all floors, but if the number of floors exceeds 7, the setting is two steps. The cross-section module is 50 mm, and the center pillar is 100 m.
m × n, the standard size of the gable pillar is 100 mm × (n−1), and the width is 50 mm × n. In this example, the central pillar and the gable pillar are separately set in this way, but a girder pillar may be further provided, or all the pillars may be set only by the central pillar.

The beam cross section is set to have the same dimensions on all floors of each beam, but in the case where the number of floors exceeds 7, two levels are set. Variations of beam formation are 730mm and 830
There are two types, mm, and the underbody beam dimensions are unified to 2030 mm. Both widths are 50 mm × n. This is because the floor height is limited to two types in the present embodiment, and when three or more floor heights are set, the variation type of beam formation is set according to the floor height type. I will keep it.

Regarding the section setting of the earthquake-resistant wall, the inner wall and the outer wall are basically the same size on all floors, but when the number of floors exceeds 7, the setting is made in two steps. The thickness of the cross-section module is 30 mm, and the pitch is set from 150 mm to 30 mm up to 270 mm. In the library of earthquake-resistant walls, the symbol EW indicates EW-shake-resistant wall, the number after that indicates the thickness in the unit of cm, and the alphabet after that indicates the type of reinforcement, and in this example, reinforcement is double. There are three types of bar arrangement, A to C. The display method of the reinforcing bars is the same as that of the pillars and beams.

In order to set the section structure for each floor, a predetermined standard section is selected from the standard section library according to the structural scale of the design property, the total number of floors, and the like. As a result, the cross-sectional dimensions of columns and beams are determined. Next, confirmed ones are sequentially selected from the column and beam cross-section libraries and displayed on the display means 4 for confirmation by the operator. When setting the earthquake resistant wall, the computer automatically selects an appropriate one from the earthquake resistant wall library according to the structural scale. In this case, for earthquake-proof walls with openings, select a predetermined opening reinforcement from the opening reinforcement library and confirm and confirm. The seismic wall is set in this way. In this way, the cross-sectional structure for each floor can be determined by successively setting the columns, beams, and earthquake-resistant walls for each floor (step 10).

Next, in step S11, the joint setting system 2d sets the joints connecting the columns, beams and earthquake-resistant walls determined as described above. The storage means 1 pre-stores a joint library representing a structure in which columns, beams, and earthquake-resistant walls are connected, and this joint library is first read when setting a joint. At each intersection of the beams of the block plan, the joint shape set by default according to 50 modules, in this case, the column core and the beam position with respect to the column are input. Further, as shown in FIG. 13, the base plane, the center, and the end are laterally divided for each basic plane outline shape of the block plan, and the balcony side and the corridor side are longitudinally divided to set each part.

As a basic design rule for setting a joint,
The position of the steel core of the column of the connection part and the position of the steel core of the beam to the column are the positions where they can be joined through the steel frame, but the centering (return dimension) of each part is 250 mm from the inner wall on the balcony side, corridor. The side is set to 250 mm from the outer wall, the gable side is set to 250 mm from the outer wall, and the center street is set to have a span beam core. The steel core is determined as shown in FIG.
By setting the position and structure of each joint in this way, the flat cross-section structure for each floor of the building frame is determined (step S12).

Although the structure of the structural frame can be designed as described above, in the present example, the bar arrangement is also automatically set. For this purpose, first, in step S13, the secondary member setting system 2e is activated to set the position and structure of secondary members such as beam and slab. That is, a girder library representing the structure of a beam and a slab library representing the structure of a slab are created in advance and stored in the storage means 1, and these libraries are first set when setting secondary members. Read out.

Although there is a close relationship between the beam and the inner slab, it is possible to improve productivity and workability without the beam, and to provide a free space without any restrictions from the skeleton. Basically, there will be no beam. However, the span and depth dimensions are limited even if the unbonded construction method currently used for slabs is used. The reason is that if the size of the space construction is secured from the floor height, the maximum slab thickness is 24.
This is because it is possible to secure only up to 0 mm. Therefore, a beam is required to ensure the free spread of span and depth dimensions. There are various layout patterns for the beam, but in order to facilitate the introduction of the industrialized construction method, it is limited to only five types shown in FIG. 15, and a complicated layout is not adopted. That is, there are five types, such as no beam, day-shaped arrangement and eye-shaped arrangement.

When setting a desired beam from the above-mentioned five types of beam, it is assumed that the beam has different attributes depending on the site where the beam is used, and the beam is grouped according to the site used. That is, the arrangement pattern of the room beam used for the room slab is selected from the above-mentioned five types,
The girder for elevator shaft is provided along the wall of the shaft in the slab to which the in-building type elevator shaft is attached, and in the case of the outside type, it is used as a connecting beam between the shaft and the skeleton. Toya (for example, elevator machine room)
On the roof of the tower and the girder for the tower that is installed in the slab of the
Create a beam library that specifies multiple beam beams corresponding to each part in advance, such as a reverse beam with jaws that surrounds the four-story slab, a reverse beam as a base of an elevated water tank on the roof of a tower with an elevated water tank, etc. It is stored in the storage means 1. FIG. 16 shows an example of a beam library.

FIG. 17 shows an example of the slab library. The slab library specifies the thickness for each construction method type, but as a slab for each construction method type,
In this example, four types of conventional slabs, unbonded slabs, void slabs, and synthetic slabs are prepared. There are slab thickness and bar arrangement structure as elements of the conventional construction slab.
Assign symbols to represent these.

For example, the slab symbol SA14 is S
Indicates a conventional construction slab, A indicates a bar arrangement type, 14
Represents the thickness, and the thickness is 14, 15, 18, 2
4 types of 0 are prepared, and the bar arrangement type is 4 from A to D.
Two types are available. Unbonded slabs among industrialized construction slabs are represented by SAB, and a number indicating the slab thickness is added to it. Span length (transverse dimension: 1x) 6.5 considering the long span advantage of unbonded slab
Make sure to select between 8.0m, vertical dimension (ly)
Is set to 8.0 to 13.0 m. The void slab is represented by SEB, and a number indicating the thickness is added to it.
The void slab is shown in lateral dimensions only, as the thickness is determined by the concrete strength and span length. The void form height suitable for the thickness thus determined is determined, and the rebar data obtained by calculation is given. The slab thickness is 210 to 240 mm and the span length is 5.8 to 6.6 m accordingly. In this example, the concrete strength is 210. The synthetic slab is basically the same as the conventional construction slab, and is identified by the symbol SK, the symbols A to D indicating the bar arrangement type, and the number indicating the thickness. However, type A bar arrangement is not set in consideration of the workability of bar arrangement.

As a slab selection procedure, in the case of a conventional construction slab, the operator selects a slab satisfying the structural calculation after the slab beam position is determined and the operator selects the slab from the slab library. To do. The condition that determines the type of unbonded slab is the vertical and horizontal dimensions of the slab. Therefore, when the vertical and horizontal dimensions of the slab are set at the planning stage, a desired unbonded slab is automatically selected from the slab library. The condition that determines the type of void slab is the lateral dimension of the slab. Therefore, when the lateral dimension of the slab is set at the planning stage, an appropriate void slab is automatically selected from the slab library. When the slab type is selected in this way, PC boards will be allocated next and the allocated PCs will be
Allocate the void formwork to the board and arrange the truss reinforcements accordingly. When selecting a composite slab, after the beam position of the slab is determined similarly to the conventional method slab, the slab design is entered and the slab satisfying the structural calculation is selected from the slab library. Once the slab type is determined,
Next, the PC boards are allocated, and the trusses are arranged according to the allocated PC boards.

As described above, among the four construction methods prepared in the slab library, it is the unbonded slab and the void slab that can automatically select the slab type depending on the span length. FIG. 3 shows a slab matrix representing the thickness of the slab with the span length as a parameter.

As shown in FIG. 2, there are two beams such as beam and slab.
When the setting of the next member (step S13) is completed, the room setting system 2f is activated in step S14 to set the basic shapes of the outside of the frame and the exit of the setback portion. In this example, the setting of this exit room is set to the above-mentioned 2
Although it is input according to the library of the next member and the parameter, the library for the exit room is created in advance, the one that meets the conditions is automatically selected from it, and it is optimal from the selected one as necessary. You may make it specify the thing.

Further, in order to set the non-structural members such as the exterior material, the cantilever slab, and the miscellaneous wall, the non-structural member setting system 2g is activated in step S15. Various libraries are prepared in advance for the setting of this non-structural member, the corresponding one is automatically selected according to the input parameters, and the most suitable one is selected from them as needed. specify.

Thus, the positions and structures of the primary members constituting the building frame, the positions and structures of the secondary members, the positions and structures of the exit rooms, and the positions and structures of the non-structural members that define the outer wall and common equipment. After setting, step S16
At, the structural calculation system 2h is activated to perform structural calculation. This structural calculation can be automatically performed using automatic structural calculation software. When the structural calculation is completed, finally, in step S17, the bar arrangement setting system 2i is activated, and the optimal bar arrangement of the columns and beams is determined based on the result of the structural calculation from the viewpoint of workability and economy. As for the seismic wall, the bar arrangement has already been decided as described above. This bar arrangement determination is automatically performed using automatic bar arrangement determination software.

In this example, data for setting the position and structure of the primary members such as columns, beams, and earthquake-resistant walls of the building frame for each floor can be obtained in this way, and the beams and slabs can be set. It is possible to obtain data for setting the positions and structures of secondary members, the positions and structures of exit rooms, and the positions and structures of non-structural members such as outer walls and common equipment. The various setting data thus obtained are stored in the storage means 1. In this way, various data stored in the storage means 1 can be read out through the input means 3 and displayed on the screen of the display means 4 or various drawings can be created by the plotter 5.

The present invention is not limited to the above-described embodiments, but various changes and modifications can be made. For example, in the above-described embodiment, after setting the structure of the building frame, the position and structure of the secondary member, the exit room, and the non-structural member are set. Need only set the structure of the building frame.
Furthermore, after the structural calculation was performed, the reinforcement of columns, beams, and seismic walls was automatically determined based on the results, but the reinforcement arrangement does not necessarily have to be determined automatically. Further, in the above-described embodiment, the plotter is provided to output the cross-sectional structure diagram of the building frame, but in the present invention, it is important to obtain data for setting the structure of the building frame, and it is not always necessary to create a drawing. No need. Also, for buildings that are set back on a certain floor,
For example, the frame of the part set back at the stage of setting the wire frame or the stage where the position and structure of the primary member on each floor are determined may be deleted. In the former case, the primary member is set with the setback taken into consideration, whereas in the latter case, the primary member is set regardless of the presence or absence of the setback. Further, in the above-described embodiment, the floor height is determined based on the total number of floors and the structure type, but if the structure type is determined in advance according to the number of floors, the floor height can be determined based on only the total number of floors. Similarly, when setting the position and structure of the primary member, if the structure type is determined in advance by the total number of floors, the position and structure of the primary member can be determined based only on the block plan, the total number of floors, and the height of each floor. It can also be set.

[0032]

As described above, according to the structural design system for a building frame of the present invention, a large number of block plans are stored in advance, and those that meet various conditions are automatically selected and further selected. Since the desired one is designated from among the designated ones, the block plan can be set extremely easily and quickly. Therefore, even if the client proposes a design change at the planning stage, it can quickly respond to it, can minimize the delay of the overall plan, and respond to the client's wishes to the maximum extent. be able to. Furthermore, after determining the block plan, the span length and the number of floors are specified to automatically set the floor height of each floor, and the columns,
Since the structure of beams and earthquake-resistant walls is automatically set, the cross-sectional shape for each floor can be easily and accurately determined.
Even if the designer of the block plan and the designer of the structure of the building structure are different persons, the structure will not conflict with the lock plan.
