Abstract
A high-rise structure with 23 floors shear walls above a large podium was studied in this paper. The nolinear analysis model of the structure was constructed with PERF0RM-3D program. Elasto-plastic time-history analysis of the hybrid structure was carried out to evaluate the overall seismic performance of the structure. Shaking table test of the whole strueture model has been done also. Comparison between the numerical a-nalysis and the test was conducted. The results show that the structure has uniform vertical stiffness and there is no week storey. Meanwhile some measures should be taken to strengthen the roof of the podium according to the shear force abrupt change. The frame structure of the underpan have enough strength and stiffness. But the coupling beam is very tall, the shear walls between the windows is weak because of the small section height. So some measures should be taken to improve the ductility of these walls.关键词
