鉴于上海环球金融中心结构体系及结构布置的复杂、结构高度及体型的超限，为了确保该建筑结构的抗震安全性和可靠性，除进行常规的计算分析外，还应对该结构进行弹塑性时程分析。本文建立了该结构的弹塑性时程分析简化模型，并编制了相应的计算程序。为了检验结构弹塑性时程分析的可靠性，首先对振动台试验的模型结构进行弹塑性时程分析，以便和试验数据进行对比。在此基础上对原型结构进行弹塑性时程分析，并对该结构进行了抗震性能评价。

上海环球金融中心大厦高101层，结构高度492m，高宽比8.49，拟建成为世界上结构主体最高的建筑物。大厦采用了三重结构体系抵抗水平荷载，它们由巨型框架、钢筋混凝土核心筒及构成核心筒和巨型型钢混凝土柱之间相互作用的伸臂桁架组成；核心筒竖向不连续，由低筒、中筒和上部筒3部分组成；二对角巨型柱在42层以上开始分叉形成倾斜曲面，巨型斜撑只设置在垂直立面上，且采用单向支撑。根据我国《高层建筑混凝土结构技术规程》（JGJ3-2002），该建筑总高超过了型钢混凝土框架-钢筋混凝土筒体最大高度190m的限值，同时高宽比超过了设防烈度7度地区为7的限值。为研究它在地震作用下的抗震性能，进行了缩尺（1/50）模型的振动台试验。试验结果表明，该结构体系合理，具有足够的水平刚度，在地震作用下位移反应不大，扭转效应比较小，满足我国抗震设防要求。

A new seismic energy dissipation shear wall structure is proposed in Ibis paper. Tile new shear wall is one with purposely built-in vertical slits within the wall panel, and rubber belts as seismic energy dissipation devices are installed in the vertical slits. In order to verify this concept, shaking table tests of a 1O-storey shear wall modcl with rubber belts filled in the vertical sifts were carried out, and comparison of seisndc behaviour was made between the new shear wa]l system and a shear wall with reinforced concrete connecting beams as energy dissipation, Furthermore, the seismic behaviour of this new shear wall is analysed by a finite element time history analysis method The test and analysis show thai the new shear wall system has a very good ability to dissipate seismic energy and is easy to use in engineering practice.

In this paper, the dynamic response of a very complex structure which has U shaped flexors and specially shaped slant culumns is described. Shaking table tests of a scale model of the building were taxied out to verify the safety of the structure and to, confirm the resulis of a finite element analvsis of the building. The elastic finhe element analysis was done with the help of Super SAP 93, a well-known structural analysis program. From the shaking table test and the finire element analysis, the dynamic eharaeleristics of the building and its maximum responses were evaluated In the ehlastic reeion the analytical results were in good agreement wilh the test results At the end of this paper, some suggestions are given for engineering design of this type of structures
