Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for automatically designing a building frame.

[0002]

2. Description of the Related Art Conventionally, a system for automatically designing a building frame is known as a building CAD. This architectural CAD
Then, display the block plan and the number of floors created in advance,
Components such as columns, girders, foundation beams, earthquake-resistant walls, and slabs will be placed on top of it. For example, the conventional building C that designs the structural frame of an apartment house made of reinforced concrete
In AD, there are a wide variety of applications and the scale is large and small. Therefore, in order to have versatility, the pillars and girders should be set in advance as standard, and automatic placement should be performed using them. I have to. When automatically placing major components such as columns and girders like this,
Pillars and girders are automatically arranged based on face-to-face information that represents the distances from the core to the pillars and girders such as frontage, depth, and floor height, which are designed in advance by the block plan. After that, necessary changes were made to each of the automatically arranged columns and girders.

After arranging the main components such as columns and girders in this manner, the girders are arranged. In the conventional construction CAD, the mainstream is that only the columns and girders are automatically arranged and the other components are input by the operator.

[0004]

In the above-mentioned conventional method for designing a building frame, the standard columns and girders are set in advance, and after automatic placement, the operator makes necessary changes and seismic resistance. Since the operator inputs components such as walls, beams, and slabs, it is difficult to standardize the components, which is disadvantageous in terms of cost and management. In addition, you can change automatically placed columns and girders, seismic walls, girders,
There is a drawback that inputting a slab or the like requires a lot of skill and is troublesome to operate, which may impose an excessive amount of labor on an operator, and it takes a long time to design a skeleton.

Further, in the conventional method of designing a building frame, since the operator inputs each line except for the main constituent elements in a line-by-line manner, and there is no recognition as a member, a design error may occur. There is. For example, since it is possible to pass a straight line through the gable pillar, an input error may occur in which the earthquake-resistant wall penetrates the gable pillar. Such an input error is extremely difficult to detect when the design of the building frame is completed, and there is a possibility that it may be noticed for the first time when the drawing is output.

The object of the present invention is to solve the above-mentioned drawbacks of the conventional automatic design method of a building frame, and to make it easy for an unskilled person to
(EN) It is intended to provide an automatic designing method of a building structure and a database used for such an automatic designing, which can design accurately in a short time and can unify the standards of constituent elements.
