[摘要]世茂深坑酒店主體建筑依崖壁建造,為獨(dú)特的上下兩點(diǎn)支承結(jié)構(gòu)體系。與考慮行波效應(yīng)的多點(diǎn)輸入不同,需要考慮幅值差的多點(diǎn)輸入地震反應(yīng),相應(yīng)的多點(diǎn)輸入采用了位移時(shí)程波而不是加速度時(shí)程波。結(jié)構(gòu)采用鋼管混凝土柱框架-支撐結(jié)構(gòu)體系,鋼管混凝土柱的非線性力學(xué)性能指標(biāo)應(yīng)用了“統(tǒng)一理論”。運(yùn)用SAP2000和ABAQUS有限元分析軟件,重點(diǎn)分析了在罕遇地震作用下結(jié)構(gòu)彈塑性時(shí)程響應(yīng)。

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
