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 Tower is composed of long-span bridges between two towers and towers in the north and south, all of which are earthquake-resistant overrun structures that are irregular in both plane and vertical directions. This paper presents a simulated shaking table test for a 1:25 scale model of the structure. The analysis of the test results shows that the structure of the south tower and the north tower of Shanghai Tower of China Merchants Bank can all meet the requirements of three-level seismic design. Under the precondition that the bridge structure meets the requirements of three-level seismic design, Force state, the earthquake does not yield design goals. In addition, it is also confirmed that the connection node between the steel bridge of the bridge and the concrete cylinder is the weak part of the bridge structure.
