| 摘 要： | 基于钢筋混凝土Z形截面柱梁柱节点的试验结果,运用有限元软件ANSYS对Z形截面柱梁柱节点进行非线性有限元分析,并与试验结果进行对比分析。同时,通过ANSYS对低周反复水平荷载作用下Z形截面柱梁柱节点的受力性能进行数值模拟分析,研究其在不同肢高厚比下的抗剪承载力和延性等受力性能,并验证了不同肢高厚比条件下模拟的抗剪承载力按规范提供的异形柱节点抗剪承载力设计计算建议公式设计是偏于安全的,剪压比最小限制可由0.19适当放宽到0.2。

| Abstract: | According to the test result of Z-shaped RC columns frame joints of reinforced concrete,ANSYS is used to do nonlinear finite element analysis of the Z-shaped RC columns frame joints,whose results are compared with those of the experiment.At the same time,numerical simulation analysis is done by ANSYS for the Z-shaped RC columns frame joints subjected to low-cyclic horizontal load,the development of shear capacity and ductility are studied under different height-width ratio.The following conclusion can be dr... |
