摘要
本文以弹塑性时程分析方法为基本手段,对上海国际金融中心三塔楼之间的大跨度连廊结构进行了罕遇地震下的碰撞分析研究。着重研究了连廊与主塔楼之间在大震下可能出现的相互碰撞以及撞击力的大小、最大碰撞力在不同支座中的分布特征等;同时,考察了发生碰撞的情况下,廊桥构件的安全性。本文采用的分析研究方法对其它类似复杂连廊结构的设计和分析具有较好的借鉴意义。
Based on the elastic-plastic time-history analysis method,the collision response of large-span corridor structure between the three towers of Shanghai International Financial Center is studied. The research work focused on the feasibility of the mutual collision,the magnitude of the impact force between the corridor and the main towers and impact force＇s distribution characteristics in space under severe earthquake. In addition,the components＇ performance is checked during collision. The analysis research method in this paper can provide significant reference to other similar complex corridor structures.
