摘　　要：招商银行上海大厦由南北两个塔楼和塔楼间的大跨度连桥组成,均属于平面和竖向均不规则的抗震超限建筑。本文介绍了对该结构进行1:25缩尺模型的模拟振动台试验。对试验结果的分析表明:招商银行上海大厦的南塔楼、北塔楼结构均可以满足的三水准抗震设防要求,连桥结构在满足三水准抗震设防要求的前提下,可以满足中震时节点处于弹性受力状态,大震不屈服的设计目标。此外,还证实了连桥钢桁架与混凝土筒体连接节点是连桥结构的薄弱部位。China Merchants Bank Shanghai Building is composed of the North and the South Tower,a large-span link-bridge between the two towers.The configuration of the horizontal and vertical plan does not satisfy the rules of the seismic code.This article gives a introduction to the shaking table test of a 1;25 scale model.The results of the test shows that the behavour of the north tower structure、south tower structure and the link-bridge structure can meet the requirement of the three-level seismic-resisting design.And the link-bridge structure can also remain elastic node under medium-level earthquake,does not yield under rare-level earthquake.In addition,the test shows that the joint of the link-bridge and the concrete tube is the weakest part of the link-bridge structure.
