摘　　要：高烈度区异形柱框架结构节点常出现剪压比超限问题,且很难调整满足。针对此问题,首先分析节点核心区受剪的水平截面剪压比公式,指出解决的方向。然后用一案例试算验证,根据计算结果总结节点剪压比的变化规律。提出了解决问题的几种措施,可有效解决节点超限问题,避免设计人员大量耗时调整试算。The shear compression ratio of special-shaped column frame structure joints in high intensity area often exceeds the limit,and it is difficult to adjust.In order to solve this problem,this paper first analyzes the shear compression ratio formula of the horizontal section in the joint core,and points out the direction to solve it.Then a case is used to verify the calculation results and summarize the change rule of shear compression ratio of the joint.Several measures to solve the problem are put forward,which can effectively solve the problem of node overrun and avoid a lot of time-consuming adjustment and trial calculation by designers.
