There are three floors underground, and 43 floors are on the ground. The building height is 198.9 meters. In this paper, in order to study the seismic performance of the structure under rare intensity of 7 earthquake, NosaCAD and Perform-3D were used to perform elasto-plastic time history analysis. Frame element models of NosaCAD and Perform-3D are both consisted of three different stiffness segments: a linear elastic segment located in the middle and another two elasto-plastic segments located at both ends. Trilinear moment-curvature hysteretic model is adopted for the elasto-plastic segments of concrete beams and steel reinforced concrete beam. And fiber model is employed to describe the nonlinear behavior in the elasto-plastic segments of column. In NosaCAD, the flat shell finite element is used for shear wall and elastic plate element is used to simulate the structural slab. In Perform-3D, macro layered element is adopted to simulate shear wall component and rigid diaphragm assumption is employed. The results indicate that under rare earthquake, the yielding hinges firstly occur on some coupling beams. The limited concrete has crushed on few shear walls and the column was only damaged with some tensile cracks. The maximum inter-story drift of the structure can meet the requirement of Chinese code. The sequence and distribution of damages on components of the structure are reasonable, which can dissipate some dynamic energy. The structure satisfies the code requirements of no collapse under rare earthquakes. The calculation results, such as the global response, weak story and damage condition got by the two softwares show an agreement to a certain degree. It is suggested that the envelope value of multi-software analysis can be used to ensure the safety of such complex structures.
