| 摘 要： | 介绍了新型方钢管混凝土柱与钢梁节点在低周反复荷载作用下的试验结果,分析了内填混凝土、加劲肋长度和梁柱相对尺寸等对节点抗震性能的影响.试验结果表明:各试件实测滞回曲线比较饱满,具有良好的耗能性能.运用ANSYS8.0对各节点试件在低周反复荷载作用下的滞回性能进行非线性模拟计算,分析内填混凝土、加劲肋长度等因素对节点受力性能的影响,结果表明:内填混凝土和加劲肋长度对节点受力性能的影响较大,有限元所得的骨架曲线与实测曲线吻合较好.

| Abstract: | Experimental results of new type joints between the column and the steel beam of concrete-filled rectangular steel tubular(CFRT)under reversed cyclic loads are presented.The earthquake resistant capacity of the joint is influenced by infilled concrete,stiffener length and relative dimensions of column and beam.It is found that the hysteresis curves obtained in the experiment are full and the joints have a good energy dissipation capacity.The nonlinear finite element models are also used to analyze the hyste... |
