【摘要】 通过ANSYS对低周反复水平荷载作用下Z形截面柱受力性能进行数值模拟分析,研究其不同轴压比(下的抗剪承载力他和延性等受力性能,轴压比(从0.1变化到0.9。结果表明,轴压比(的变化对低周反复荷载下Z形柱的受力性能影响较大。最后,给出可供实际工程设计参考的抗剪承载力计算公式,并将公式的计算值与试验值进行比较,验证了公式的可行性。更多还原

【Abstract】 According to numerical simulation analysis by ANSYS of behavior of Z-shaped RC column subjected to low-cyclic horizontal load,the shear capacity and ductility were studied under different axial compression ratio μ,which arranged from 0.1to 0.9.The results showed that changes of axial compression ratio μ had a great impact on behavior of Z-shaped RC column.Finally,the formula of the shear capacity was proposed for reference of practical engineering design.The value of the shear capacity calculated by using the formula was compared with the experimental data,which verified the feability of the formula.更多还原
