［摘要］世茂深坑酒店主体建筑依崖壁建造，为独特的上下两点支承结构体系。与考虑行波效应的多点输入不同，需要考虑幅值差的多点输入地震反应，相应的多点输入采用了位移时程波而不是加速度时程波。结构采用钢管混凝土柱框架-支撑结构体系，钢管混凝土柱的非线性力学性能指标应用了“统一理论”。运用SAP2000和ABAQUS有限元分析软件，重点分析了在罕遇地震作用下结构弹塑性时程响应。

Abstract:Shimao Chasm Hotel is constructed along the cliff, and both sides of the structure are supported. Unlike the seismic analysis considering traveling effect, the time-history seismic analysis considering the difference of amplitude was carried out. Earthquake time-history of displacement was used, rather than time-history of acceleration. This building adopts the braced steel frame structural system with concrete-filled steel tube(CFST) column. ‘Unified Theory of CFST’ was applied for obtaining the nonlinear composite characteristics indexes. Using the finite element program software SAP2000 and ABAQUS, the elastic-plastic reaction of the structure during severe earthquake was analyzed.
Keywords:multi-support excitation；difference of amplitude；time-history of displacement； elastic-plastic analysis； concrete filled steel tube
