Abstract
This paper gives a brief introduction to the design and background of performance-based seismic design, the basic theoretical framework and requirements of performance-based design, the application and development of performance-based design in the world. Based on the theory of performance-based seismic design, the design, analysis and research of the engineering example are carried out to demonstrate the safety of the structure. Based on the analysis and design of a super high-rise project, this paper analyzes the type and extent of the structural overrun in the engineering example, and determines the seismic performance of the structure. Using PKPM SATWE to model and calculate the PMSAP and GSSAP, three common structural design software of earthquake in small earthquakes, the elastic calculation results were analyzed; the structure of elastic time history analysis and modal decomposition method were analyzed; in the earthquake, remove the structure of minor components non seismic. Analysis on the bearing capacity of structural component performance according to its seismic performance objectives; for the construction of local floor holes such as floor irregular plane, in the seismic elastic slab stress analysis, to ensure the earthquake floor can reliably transfer the horizontal force; using finite element software PUSH&EPDA and ABAQUS are static and dynamic pushover analysis of buildings under rare earthquake; considering the additional P－Δ effect may bring over height analysis.
