“…The floor rigid rotational deformation is caused by the bending deformation of the lower floor. For the frame structure the shear deformation is dominant [1]. However, for the structure with bending deformation, the structural damage is directly related to the maximum bending rotational deformation, which can be called physical deformation [13].…”

“…The traditional frame structure has better mechanical behaviour when it is subjected to gravity loads. But the lateral stiffness of the frame structure is caused by the bending and shearing stiffness of the beam and column, and the lateral stiffness is smaller than other structural systems [1]. With the increase of building height, structural deformation cannot be ignored by horizontal loads such as wind and seismic load.…”

The high-rise frame-diagrid structure is a new type of dual system structure. The inner frame part can create a large space, and the external diagrid part can provide a larger lateral stiffness. In this paper, the lateral deformation formula for the high-rise frame-diagrid structures is derived. The bending deformation of the structure is divided into the bending rotational deformation and the floor rigid rotational deformation. The physical storey drift is proposed. The physical storey drift is directly related to the structural damage. When the structure is in the plastic state, the structure maximum storey drift and maximum physical storey drift are in different positions. It is recommended to use both storey drift and physical storey drift as structural deformation limitation criteria. Finally, the proposed method is used to structural parameters analysis for the high-rise frame-diagrid structure. It provides reference for the structural design.
