［摘要］汇隆商务中心2A#塔楼为钢筋混凝土框架-核心筒结构，为满足在建筑四周立面不同标高设置中庭的要求，采用带V撑的转换结构进行上部结构转换。通过YJK和ETABS两种软件对结构进行了多遇地震下的振型分解反应谱分析和弹性时程补充分析，采用MIDAS Building软件对结构进行了罕遇地震下的弹塑性时程分析，对转换V撑处的楼板进行了应力分析，此外还进行了施工模拟分析与节点有限元分析。结果表明，该结构体系合理且具有良好的抗震性能，结构整体抗震性能能够达到《高层建筑混凝土结构技术规程》（JGJ 3—2010）规定的C级性能目标要求，结构整体变形及应力水平均处于合理的范围。

Abstract:The reinforced concrete frame-shear wall structure system was adopted in tower 2A# of Huilong Commercial Center. To meet the requirements of the atrium set around the building at different elevation, transfer structure with V shaped brace was used for the transformation of upper structure. The structure was analyzed by YJK and ETABS programs for response spectrum analysis and complementary elastic time-history analysis under the frequent earthquake. Elastic-plastic time-history analysis of the structure was performed by MIDAS Building program under rare earthquake. The stress analysis of the floor slab at the transition V-shaped brace was carried out. In addition, the construction simulation analysis and the finite element analysis of the joints were also carried out. Analysis results show that the overall structural system is rational and has a good seismic performance, the overall seismic performance of the structure can meet the C-level performance target of  Technical specification for concrete structures of tall buildings (JGJ 3—2010), and the deformation of the whole structure and the stress levels are in a reasonable range.
