摘要
常州润华环球中心主塔楼为总高度300m的超限高层,采用了带加强层的钢管混凝土框架-钢筋混凝土核心筒混合结构体系。采用通用有限元程序Abaqus对该结构进行了罕遇地震作用下的动力弹塑性时程分析,考察结构的整体抗震性能指标,并着重分析了核心筒剪力墙、框架钢梁、钢管混凝土柱、环带桁架、连梁以及楼板等典型构件的损伤破坏程度,为该结构及其他类似结构的性能设计提供参考。
The Changzhou Runhua World Center is a has a composite structural system that is composed of high-rise building with the total height of 300 meters. It a concrete filled tube frame and a RC core wall. Elasto- plastic dynamic analyses under rare occurred earthquake were conducted by using the Abaqus software. Struc- tural performance was evaluated in this article. Some typical component damages were focus on in this study, which includes the core wall, steel frame, concrete filled tube column, belt truss and slab. The methods and results presented in this paper offer reference to the design of this project and can also be used useful for other similar structural designs.
