Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, a personal computer (hereinafter referred to as a personal computer) is used,
Support the structural planning by determining whether the bearing wall of the house has sufficient strength. 1 and 2 are plan views of the first and second floors, and FIGS. 3 and 4 are east side elevational views and south side elevational views. The case of performing strength evaluation will be described as an example.

In determining the strength of the bearing wall, first, on the building shape input screen shown in FIG. 5, the outline of the first floor of the house is input while drawing a diagram on the screen of the personal computer.
That is, using the input tool such as the mouse 1 attached to the personal computer, the outer wall line L1 on the first floor of the house is input as a polygonal line with reference to the plan view of FIG. As the input method of the outer wall line L1, a polygon input for designating each polygon by designating each vertex of the polygon, a BOX, that is, designating the rectangle by designating two vertices located on the diagonal of the rectangle. An appropriate method such as a BOX input to make the selection can be used.

Subsequently, as shown in FIG. 6, the outer wall line L2 on the second floor of the house is entered with reference to the plan view of FIG. At this time, if the entered outer wall line L1 of the first floor is displayed by a solid line or a dotted line, the outer wall line L of the first and second floors is displayed.
This is preferable because the relative positions of 1 and L2 can be easily grasped.

When the input of the outer wall lines L1 and L2 is completed, subsequently, the data on the specifications of the roof of the house are input to the personal computer. That is, in the load element input screen shown in FIG. 7, when the outer wall line L2 on the second floor that has been input is displayed and the range of the thatched lowering portion A is designated by the mouse 1 or the like and input, for example, this thatched lowering portion A Displayed by cross-hatching.

Next, the shape of the roof of the house is input on the roof shape input screen shown in FIG. In the present embodiment, the roof shape is classified into, for example, 9 types of type 1 to type 9, and the shape model for each type is displayed near the right end portion of the roof shape input screen. The operator is X
For each of the (horizontal) direction and the Y (longitudinal) direction, it is selected which of the types 1 to 9 the roof belongs to, and the information is input to the personal computer.

Here, the roof in the X direction (the roof of the second floor)
The shape of is considered to be type 3 based on the east side elevation view of FIG. 3, and the number “3” is input. Although the type 3 shape model and the shape of the roof in the east side elevation are symmetrical, the symmetrical ones belong to the same type. On the other hand, the shape of the roof in the Y direction (the roof of the second floor) is considered to be type 7 based on the south side elevation view of FIG. 4, and the number “7” is input. In addition, the height of the house-the height of the house (unit: m) is input for each of the X and Y directions.

When the input of the data regarding the specifications of the roof and the like is completed, next, on the load bearing wall arranging screen of FIG. 9, first, a desired number of load bearing walls 2 are placed at desired positions on the outer wall line L2 on the second floor of the house. And perform strength evaluation. At this time, the computer is
Based on the data regarding the specifications of the outer wall line L2 and the roof, etc., which have already been input, the reference number LX and LY of the load bearing walls 2 are calculated for each of the X and Y directions, and displayed in the upper right corner of the screen. In this case, the standard number of sheets LX in the X direction is 3.6 sheets,
The standard number of sheets LY in the Y direction is 5.2.

The input operator inputs and arranges the bearing wall 2 along the outer wall line L2 on the screen using the mouse 1 or the like while referring to the reference number LX and LY. The input bearing wall 2 is displayed by a thick line, for example. When the placement of the load bearing walls 2 is completed on the screen, subsequently, the personal computer, based on the built-in program, bears the burden rate P and the rigidity reduction value Q of each load bearing wall 2.
Is calculated, and the calculation result is displayed on the load bearing wall load horizontal force screen of FIG. Here, the load factor P of each load bearing wall 2 is a value obtained by dividing the load bearing force by the horizontal allowable force, and any load bearing wall 2
When the load factor P of the above exceeds “1”, it becomes necessary to change the arrangement of the load bearing walls 2.

The load factor P is displayed on the lower side of each load bearing wall 2 in FIG. 10, and the rigidity reduction value Q is displayed on the upper side. In the case of this example, since the burden rate P is "1" or less for all the load bearing walls 2, the placement of the load bearing walls 2 is accurate,
No modification needed. On the other hand, when the load factor P of one of the load bearing walls 2 exceeds “1”, the number of load bearing walls 2 is increased, or after the correction such as changing the position where the load bearing walls 2 are arranged, Again, the personal computer is made to calculate the burden factor P and the rigidity reduction value Q, and it is confirmed that the burden factors P of all the bearing walls 2 are "1" or less.

The burden rate P of all the bearing walls 2 is "1".
Even in the following cases, if the load factor P of any or all of the load bearing walls 2 is excessively small and it is expected that the required strength can be obtained even if the number of load bearing walls 2 is reduced, the load bearing walls 2 It is safe to make corrections to reduce the number of cards. Further, as shown in FIG. 11, if necessary, instead of the burden ratio P, the burden force R (unit: kgf) can be displayed on the screen.

After the placement of the load bearing walls 2 along the outer wall line L2 on the second floor is completed, the load bearing walls 3 are subsequently placed along the outer wall line L1 on the first floor on the load bearing wall layout screen of FIG. Also here, the reference number LX and LY of the load bearing walls 3 in the X and Y directions.
Is displayed in the upper right corner. In addition, the load-bearing wall 2 on the second floor that has already been arranged is displayed by a solid line or a dotted line, and the input operator
The load bearing walls 3 on the first and second floors are arranged in consideration of the fact that the positions of the load bearing walls 3 and 2 are not excessively overlapped.

When the arrangement of the load bearing walls 3 on the first floor is completed, the personal computer calculates the burden rate P of each load bearing wall 3 as described above,
It is displayed on the load bearing wall horizontal force screen of FIG. When the load factor P of one of the load bearing walls 3 exceeds “1”, the load factor P is calculated again after correcting the number of the load bearing walls 3 or the arrangement position. If necessary, as shown in FIG. 14, the bearing force R of each bearing wall 3 can be displayed. In addition,
The present invention is realized by recording, in a computer language, a recording medium such as a floppy disk or a CDROM for using a program for causing a personal computer to perform the processing described in the section of this embodiment and using or selling the program. The method can be effectively spread.
