摘　　要：对于结构体系中存在倾斜构件如斜柱、斜撑、斜墙等的高层建筑结构,倾斜构件轴力的水平分量需通过楼盖体系传递,这使得楼盖体系在自重下存在较大的拉应力。带斜柱的框架-核心筒结构,其斜柱转折处的水平力通过楼盖体系传递到核心筒,设计时应采取措施保证该水平力在梁柱节点、楼盖、墙梁节点、核心筒内传力的可靠性。还应结合施工模拟分析、实体元有限元分析等手段,根据计算结果采取相应的加强措施。结果表明,带斜柱的框架-核心筒结构,其斜柱转折处的水平力在设计时应采取措施保证该水平传力的可靠性。For high-rise building structures with inclined members such as inclined columns,diagonal braces and inclined walls in the structural system,the horizontal component of the axial force of the inclined members needs to be transmitted through the floor system,so that the floor system has a large tensile stress under its own weight.For the frame-corewall structure with inclined column,the horizontal force at the turning point of the inclined column is transmitted to the corewall through the floor system.In the design,measures should be taken to ensure the reliability of the horizontal force transmitted between the beam-column joints,floor,beam-wall joints,and corewall.In addition,corresponding strengthening measures shall be taken according to the calculation results in combination with construction simulation analysis,solid element finite element analysis.The results show that for the frame-core tube structure with inclined columns,it measures should be taken in the design to ensure the reliability of the horizontal force transmission at the turning points of the inclined columns.
