摘　　要：苏州现代传媒广场办公楼建筑高度为214.8m,塔楼与部分裙房以大跨多层空间桁架连成整体,结构体系复杂,高度等多项指标超限,属超限高层建筑。介绍了其各组成部分的结构体系以及设计分析内容,并基于PERFORM-3D程序对结构进行动力弹塑性时程分析,以判断结构在大震作用下的性能。根据分析结果,对竖向构件、垂幕形中庭、大跨多层空间桁架连接体等重要部分采取有针对性的抗震措施。同时为准确计算塔楼底部3层跃层柱的计算长度,对整体进行了屈曲稳定分析。The height of Suzhou Modern Media Square Office is 214.8m.Tower and podium are combined together with multi layers space truss.Structure system is complex,and many indexes exceed the limit,so it belongs to super high-rise building.The structure system and design contents of each part were introduced.Dynamic elastic-plastic time history analysis was done by PERFORM-3D in order to analyze the performance of the structure under rare earthquake.Based on the results,special treatments were taken to the vertical components,vertical curtain type atrium and large-span space truss.At the same time,in order to accurately calculate the effective length of bottom three layer columns,the whole buckling stability analysis was done.

关 键 词：结构体系 超限高层 性能化设计 大跨空间桁架 屈曲稳定性
