Abstract:The main tower building of Haikou Center adopts steel frame-corewall structural system with strengthening layers and inclined supports. Programs of SATWE and ETABS were used to conduct response spectrum analysis and time-history analysis on the structure under frequent earthquake respectively and the calculation results were compared. In order to reach the goal of multiple seismic defense lines of the structure, statistical analyses were conducted on the distribution relations of the horizontal shear force and overturning moment between the frame and supports, between outer frame and corewall. The corresponding shear force adjustment was conducted. Appropriate performance objectives were set for the structure. Calculation and analysis of the structure were completed under fortification earthquake. ABAQUS finite element analysis software was adopted for dynamic elastic-plastic time-history analysis on the structure under rare earthquake, so as to realize the performance-based seismic design of the structure.
Keywords:main tower building of Haikou Center; steel structure; out-of-code high-rise structure; multiple seismic defense lines; performance-based seismic design
