Some seismic performance indexes,such as the seismic response of the overall structure,the strain of material and the deformation of main structural components,were proposed to comprehensively assess the seismic performances of a structure in the aspects of overall and local responses. Then,nonlinear dynamic time- history analyses were carried out to study the seismic performances of a super high- rise frame- core wall structure with vertical irregularity and exceeding height by adopting Perform 3D.The results show that (1) the deformation of the overall structure meets the requirements of the specification; (2) the deformations of the main force components are basically in serviceable state; and (3) although plasticity concentrates on shear walls and frame girders at the storey where the structural layout retracts,the average deformations of the components are still in serviceable state.Thus,it is concluded that the proposed seismic performance indexes can be achieved by super high- rise frame- core wall structures.
