- Abstract:
- According to different structure systems, the lateral displacement modes of tall buildings are classified. The difference of storey drift between frame and shear wall is analyzed in this paper. Then, the potential problem that the storey drift angles, which are calculated by the storey lateral displacement difference, is regarded as the deformation control parameter of shear wall structure is presented. Based on the characteristic of shear wall structure, the floor displacement is divided into destructive floor displacement and nondestructive floor displacement. Similarly, the storey drift is divided into nominal storey drift and destructive storey drift . Nondestructive floor displacement is produced by rigidity rotation of the floor, and the proportion of nondestructive floor displacement is accumulated gradually from the base to roof for shear wall structure. In this paper, applying the inverted triangular distribution of lateral force to the cantilever wall with identical section, the displaced shape is regarded as the approximate lateral displacement curve. The relationships among nominal storey drift , destructive storey drift , interstorey rotational drift angle and bending curvature of section is derived, and practical formulas to calculate the destructive storey drift is presented. Finally, the relationship of nominal storey drift, destructive storey drift, interstorey rotational drift angle and bending curvature of section is explained. Moreover, the practical formulas to calculate the destructive storey drift are confirmed, and the validity and feasibility of the method is verified.
