摘　　要：在综合考虑上海中心大厦主体结构与其幕墙结构之间相互影响的基础上,建立了大厦工程的全尺度有限元模型,分析了大厦的低阶模态,并分析了多遇地震工况和罕遇地震工况条件下幕墙加速度放大系数、幕墙层间位移角和幕墙支撑结构应力的分布情况.结果表明,大厦幕墙结构具有较好的抗震性能,符合抗震设防目标.Aiming at the curtain wall structure of Shanghai Center Tower,this paper established a finite element model of the real-scale building by considering the combination of the curtain wall and the principal structure,then the lower order modes of the building was predicted.The distribution of the acceleration magnification factor,inter-story drift ratio and stress of supporting structures was investigated under light earthquake and severe earthquake.The numerical results indicate that the designed curtain wall structure has an outstanding performance on seismic resistance,and it meets the requirement of the engineering application.
