Since the area of the building is small, there is a problem that the damping effect of the building is small. It is conceivable to increase the number of the vibration suppressing bracing members 17 used in order to improve the vibration damping effect of the building, but in this case, it is uneconomical as well as being restricted by the plan of the building. The problem arises. In addition, in order to improve the vibration damping effect of the building, it is possible to increase the cross section of the vibration suppressing bracing member 17, but in this case, there is a problem that the plan of the building is restricted.
