2. Description of the Related Art Conventionally, as one of construction methods, there is a wet construction method in which a material such as concrete is mixed with water and finished, and then the work is completed only after drying, but in the wet construction method, concrete is used. Therefore, especially in the case of a high-rise building structure, a large weight is applied to the lower layer, which is not suitable.

Therefore, for example, in the case of a high-rise building structure,
The dry method is adopted without using concrete. The dry method uses steel frames for beams and columns, and after completing the floor slab,
A partition wall is installed between the upper and lower floor slabs.

The high-rise building structure constructed by the dry method has a flexible structure due to the steel frame, and is easily shaken by an external force such as an earthquake or wind. The floor slab is displaced horizontally,
