基于钢筋混凝土Z形截面柱框架中间层中节点的低周反复试验结果，利用有限元软件ANSYS建立数值分析模型，对低周反复荷载作用下混凝土Z形截面柱框架中间层中节点受力性能进行了非线性有限元分析，研究了不同轴压比下节点的抗剪承载力性能。结果表明，轴压比的变化对Z形柱中节点抗剪承载力有一定影响，建议实际工程设计Z形柱中节点的轴压比控制在0.1～0.5为宜。

According to the test result of interior joints with Z-shaped RC column under low-cyclic loading, software ANSYS was used to establish numerical analysis model. The nonlinear finite element analysis was done by ANSYS for interior joints with Z-shaped RC column under low-cyclic loading, the shear capacity of interior joints were studied under different axial compression ratio. The results showed that changes of axial compression ratio had a impact on the shear capacity of interior joints with Z-shaped RC column under low-cyclic loading. The axial compression ratios are Suggested to control in 0.1 to 0.5 for interior joints with Z-shaped RC column of practical engineering design.
