　　利用有限元软件SAP2000，对SRC框架-RC核心筒混合结构的不同加强层设置方案进行地震作用下的反应谱分析，研究在弹性阶段“虚拟伸臂”对SRC框架-RC核心筒混合高层结构顶点侧移，力学性能等方面的影响规律。结果表明：只设环带，环带本身的刚度和数量对混合高层结构顶点侧移和柱的剪力有较大影响；能有效的减小剪力滞后效应，更好地发挥外框柱的整体作用；环带的设置会加大水平加强层剪力突变这一不利现象。

Through finite element analysis software SAP2000,this paper firstly conducts the response spectrum analysis for different design schemes of outrigger storey in the SRC frame- RC core tube hybrid high- rise structures,which are subjected to wind load and seismic action. Then,it studies the influence of virtual outrig-ger in the elastic region on the top horizontal displacement and mechanical properties of the SRC frame-RC core tube structure . The results indicate that when the strengthened storey is established only with belt trusses, the number and the rigidity of belts has further effects on top horizontal displacement of high-rise frame-core wall structure and the shearing force of columns,which can effectively weaken the shear-lag effect and better display the overall function of all outside frame columns. What’s more,the belt trusses can increase the disad-vantageous effects of shear mutation on the horizontal strengthened storeys.
