摘要
超高层办公塔楼总建筑高度为163. 55m,采用双重抗侧力结构体系:钢筋混凝土框架+核心筒结构体系。结构在第二层处有局部大开洞以及穿层柱,为找到结构薄弱部位并予以优化,在初步设计阶段的前期对结构进行地震作用下的弹性时程分析;为判断结构在大震作用下是否存在薄弱层及评价该结构在罕遇地震作用下的抗震性能,进行了大震作用下静力弹塑性分析;最后对结构进行了抗震性能优化设计及采取了加强措施。
The high-rise building is 164 m high and adopts reinforcing concrete frame-corewall structural system. There is a big opening hole and column on the second floor. In order to find the weak parts of the building and optimize them,the elastic time history analysis under earthquake was carried on in the early stage of draft design phase. Model is used to determine whether there are weak story under dramatic earthquake so as to evaluate the structure performance and static elastoplastic analysis. Finally the seismic performance optimization and the corresponding strengthened are conducted.
