2. Description of the Related Art When a building frame is composed of a core consisting of multi-story seismic elements and an outer frame for the purpose of securing a large space, the core shares most of the horizontal force due to the difference in rigidity. To do. Therefore, the deformation of the frame due to seismic force or wind pressure is dominated by the deformation of the core, but the frame with multiple layers of seismic resistant elements tends to be of bending deformation type as the height increases, so the core deformation is reduced. It becomes a design issue for high-rise buildings.

The reduction of bending deformation of the core can be solved by increasing the rigidity of the entire frame including the outer peripheral frame. However, the rigidity of the entire frame is increased and a design in which the core and the outer peripheral frame share an equal horizontal force. Then, the seismic force input to the outer frame becomes excessive, the deformation of the building becomes shear type, and the vibration control device does not work effectively. On the contrary, if both are separated and the core is designed to bear most of the seismic force, the overturning moment and horizontal displacement in the core leg will become excessive and the cross-sectional area will increase. In some cases, the design becomes impossible because of the necessity of raising the cost.
