Abstract: The 5# tower of the Greenland Business Center in Shunde City is 229.6m-height with RC frame-core structure system. The seismic performance objectives are determined. Performances of the structure were verified based on bearing capacity and deformation under different levels, including elastic analysis under frequent earthquake, unyielding analysis under intermediate earthquake, the elastic-plastic time-history analysis under rare earthquake. Key joints of the conversion truss are researched by finite element analysis. The above analysis is to accomplish the expected seismic performance objectives.
Keywords: out-of-code high-rise structure; perform-based seismic design; elastic-plastic time-history analysis; conversion truss
