| 摘 要： | 利用ANSYS有限元程序,对低周反复荷载作用下Z形截面钢筋混凝土柱框架节点受力性能进行了非线性有限元分析,研究了不同节点配箍率对节点裂缝发展、抗剪承载力、延性和耗能能力的影响。结果显示节点配箍率对框架节点受力性能的影响较大,并指出在低周反复荷载作用下Z形柱节点核心区翼缘上裂缝呈现"X"型。建议在实际设计中对Z形柱节点配箍率取为0.7%至0.8%。

| Abstract: | According to numerical simulation analysis by ANSYS finite element program of behavior of Z-shaped RC columns frame joint subjected to low-cyclic horizontal load,the development of joint crack,shear capacity,ductility and energy-consumption capacity were studied under different stirrup reinforcement ratio.The results showed that the joint stirrup ratio have greater impact on mechanical behavior of frame joint,and pointed out that the Z-shape column showing X-type cracks in the core area of the flange under low-cyclic load.It was suggested that the stirrup ratio showld be 0.7% to 0.8% for the actual design of the Z-shape RC columns. |
