摘要

上海某在建带高位转换层超限高层结构,设计采用型钢混凝土框架-钢筋混凝土核心筒结构体系,结构地上共53层,高度250m。由于其高度超限,且同时存在加强层及超高位转换层,属于B级复杂高层建筑,需对其进行地震模拟振动台试验和精细的结构分析。采用通用有限元程序对缩尺模型结构的抗震性能进行数值模拟分析。结果表明,该结构体系能够满足抗震设防要求,计算结果与试验测量值基本一致。
A 53 storey super tall-building with high-level transfer storey is under construction in Shanghai. Its height is about 250m.The central RC tube and peripheral SRC frame with two outrigger trusses are employed to resist lateral and vertical loads.The height of the building clearly exceeds the stipulated maximum height of 190m for a composite frame/reinforced concrete tube building.Besides,it is classified as B grade complex tall building due to the strengthened storey and high-level transfer storey.Thus,the scaled model shaking table test and a refined FEM computation are required for a thorough understanding of its seismic behavior.It is shown that numerical results are compared well with the test data and the structure can meet the requirements of earthquake resistance demands.
