[摘要] 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T字形大跨度连廊结构进行了分析研究，在评价其自身抗震性能的基础上，重点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；此外，还研究了设置于连廊中的钢板剪力墙的屈曲问题。分析结果表明，罕遇地震下，连廊本身性能满足预期目标，连廊与主塔之间的撞击力小于设计水平，在考虑钢板剪力墙屈曲的不利影响后，连廊仍然能满足安全要求。所采用的分析研究方法对其他类似复杂连廊结构的设计和分析具有较好的借鉴意义。

Abstract: The elastic-plastic time-history analysis was carried out to a “T” shaped long-span corridor structure between the three towers of Shanghai International Financial Center. On the basis of seismic performance evaluation, this paper studies the mutual collision and the magnitude of the impact force between the corridor and the main towers during severe earthquake. In addition, the buckling problem of steel plate shear walls in the corridor is investigated. The analysis results show that, during severe earthquakes, the corridor’s performance meets the expected demands and the magnitude of the impact force is less than the design level. Besides, the corridor itself still meets the safety requirements considering the adverse effects of steel plate shear walls’ buckling. The analysis research methods in this paper can be significantly referenced to other similar complex corridor structures.
