摘　　要：嘉晟国际高层办公楼地上28层,建筑高度124.200m,主要论述该项目采用的结构体系,柱脚设计,钢支撑水平分力在地下室传递,钢支撑连接节点应力分析。采用YJK对结构进行整体计算分析和Midas FEA进行节点应力有限元分析,结果表明,各项指标符合规范要求.Jiasheng international high-rise office building 28 floors above the ground,building height 124. 200 m,using concrete-filled steel tube-steel braced composite structure system,the tower is arranged according to the offset cylinder body,the main introduction of multi-story basement concrete-filled steel tube column foot form design,the analysis principle of the transfer of the horizontal component of the steel brace to the foundation and the steel brace in the basement,the stress analysis of the joint between the steel brace and the concrete filled steel tubular column,the calculation and analysis of the lateral stiffness ratio of the large opening in the second floor slab,y JK is used to calculate the whole structure and Midas FEA is used to analyze the joint stress. The results show that all the indexes meet the requirements of the code.
