Further, the column "KT1" is also made of square steel having a rectangular cross section, and its vertical and horizontal dimensions are the same as those of the column "C4", but its thickness is smaller than that of the column "C4".

For example, when the input operator selects and inputs a column "H", the cursor is positioned on "H" in the display area F and clicked, as shown in FIG.
The name “H” is highlighted in 2 and the column “H” can be input in this state. At the time of input, first, a cursor (not shown) is positioned at one end of the web 10a of the H-shaped steel 10 constituting the column "H" to be input, that is, at a connection point between the web 10a and one flange 10b. When clicked, the personal computer 1 recognizes and stores the point S1 at which the click was made. Here, as the point S1, the large dot 7 or the small dot 8 closest to the cursor at the time when the above-mentioned click is performed is selected.

By simply clicking the two places with the left button 3a of the mouse 3, an image representing the cross-sectional shape of the H-shaped steel 10 is created and displayed in the image display area A2. Thereby, the input of the ramen column to the floor plan can be easily performed. In this embodiment, the H-shaped steel 10 constituting the ramen column has only one kind of cross-sectional dimension. However, a plurality of types of H-shaped steels 10 having different cross-sectional dimensions are prepared and the H-shaped steel 10 shown in FIG. In the display area F, the input operator may be allowed to select the H-shaped steel 10 having a desired size.

Next, a method of inputting the support columns "C1" to "C4" will be described. When a support column, for example, the column “C2” is input, “C2” is displayed in the display area F of FIG.
Is selected and clicked with the left button 3a of the mouse 3,
As shown in FIG. 10, “C2” is highlighted in the type display section D2, and in this state, the input of the column “C2” becomes possible. To actually input the column “C2”, a cursor (not shown) is positioned at the center point P of the square cross section of the square steel 11 constituting the column “C2” to be input and clicked.
Based on this, the image data of the column “C2” is created by the personal computer 1, and the cross-sectional shape of the column “C2” made of the square steel 11 is displayed so as to surround the center point P as shown in FIG. Together with the symbol "C2" indicating the type of pillar
Is displayed.

Other supporting columns "C1", "C3", "C
The input of "4" can be performed in the same manner as the input of the column "C2". In this case, it is possible to change the cross-sectional dimension of each support column displayed on the input screen A in accordance with the actual cross-sectional dimension of the column. However, in this embodiment, for simplicity, each support column is The columns “C1” to “C4” are displayed with the same cross-sectional dimensions on the input screen A, and the symbol “C” indicates which type of column is used.
Identification is made by using “1” to “C4”. Pillar "KT
The same applies to the input method of “1”, and the cross-sectional dimensions on the input screen A are made equal to the cross-sectional dimensions of the support columns “C1” to “C4”.

The input positions of the support columns "C1" to "C4" and the column "KT1" need not always be designated by the center point P of the square cross section of the square steel 11 constituting them. Alternatively, the cross-sectional shape of the square steel 11 may be displayed on the input screen A by inputting the position of any one corner of the square steel 11 on the input screen A at one point.

FIG. 12 shows an example of inputting a floor plan. At the time of inputting the floor plan of each floor, for example, while inputting the beam 12 of the floor, the column of the floor immediately below the floor (the ramen column “H” made of the H-section steel 10 or the square steel 11 having a rectangular cross section) Of the supporting columns “C1” to “C4”) in the above-described procedure. For example, on the floor plan of the second floor, the beam 12 on the second floor
And the first-floor pillar located below it. In addition,
To input the beam 12, click the beam button B5 and select the type of beam 12 (G1, B3, etc. as shown in FIG. 12).
Is selected, two points at both ends of the beam 12 are clicked. Actually, in addition to the beam 12 and the column, each member such as an outer wall and a horizontal brace is input.

To delete an input member from the image display area A2, a delete button B in the operation button display area A1 is used.
When the cursor is placed on the member to be deleted and then clicked once again after placing the cursor on the member 6 and clicking once again, the image data relating to the member is deleted from the storage unit of the personal computer 1, and the image representing the member is displayed in the image display area. It is deleted from A2. When the creation of the floor plan of one floor is completed, subsequently, the floor button B7 of the operation button display area A1 is clicked, and the other floors are sequentially designated to generate the floor plan for each floor of the house.

When the structural calculation is performed at the stage when the creation of the floor plan of all floors is completed, when the structural calculation is instructed to the personal computer 1, each member whose figure is input in the above-mentioned floor plan is subjected to the conversion. Is converted into coordinate data by the application program, and subsequently, the structural calculation is executed by the structural calculation program based on the coordinate data. As a result of the structural calculation,
If it is determined that any of the members has insufficient strength, the plan is changed in order to reinforce the member or its peripheral portion.

For example, when it is determined that one of the H-shaped steel frames 10 has insufficient strength, it is possible to make a change such as adding another frame or support column near the frame. If it is determined that any of the support columns made of the square steel 11 has insufficient strength, the square steel 11 may be replaced with a square steel 11 having a larger cross-sectional dimension.
Or a change such as increasing the number of support columns. Then, after the design change, the above structure calculation may be performed again.

In the above embodiment, “C1” through “C
Although the input operator selects which of the support columns to use from "4", a selection criterion is created in advance in accordance with the use position of the support column and stored in the storage unit of the personal computer 1. Alternatively, the configuration may be such that the personal computer 1 automatically selects the type of support column based on the above selection criteria at the stage when the input operator has input the support column. As a selection criterion in this case, as shown in FIG. 12, for example, "C2" is used as a support pillar located at the outer periphery of the house, and "C4" is used as a support pillar not located at the outer periphery. Can be set in advance.

In the case of automatic selection, when the input of the floor plan is completed and the above-described structural calculation is performed, if any of the supporting columns is determined to be insufficient in strength, the personal computer 1 will not support the insufficient strength. It is preferable that the column is automatically increased in size, that is, replaced with a column having a larger cross-sectional dimension, and the structural calculation is performed again.
