摘　　要：上海某带高位转换超限高层结构高53层,结构高度250 m.该超限高层采用型钢混凝土框架-钢筋混凝土筒体结构体系.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190 m限值,属于高度超限的B级高层建筑;同时存在加强层及竖向主要受力构件高位转换层,属于B级复杂高层建筑.为研究它在地震作用下的抗震性能,进行了缩尺(1/30)模型的振动台试验.试验结果表明,该结构体系合理,具有较大的水平刚度,在地震作用下位移反应和扭转效应比较小,满足规范抗震设防要求.The height of a 53-storeyed super tall-building with high-level transfer storey is 250 m. The central reinforced concrete （RC） tube and peripheral steel reinforced concrete （SRC） frame with two outrigger trusses are employed to resist vertical and lateral loads. According to the Technical Specifications for Concrete Structures of Tall Building （JGJ3--2002）, the height of the building clearly exceeds the stipulated maximum height of 190 m 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. A scaled model （1/30） was made and tested on the shaking table to study its dynamic characteristics, seismic responses and to evaluate its capacity to withstand earthquakes. The test results show that the structural system is an ideal solution for the building to withstand earthquakes. The inter-storey drifts and the overall torsions meet the requirements regulated by Chinese Code.
