摘　　要：提出了隔板单边贯通柱壁板的方钢管混凝土柱-钢梁节点,对3个节点试件进行了伪静力试验研究。采用有限元程序ANSYS对节点进行了循环荷载作用下的三重非线性有限元分析。试验结果与有限元计算结果比较表明,节点具有很好的强度、刚度、延性和耗能能力。A new design of single through interior diaphragm connections for concrete filled square steel tubular column and steel beams was proposed. A total of 3 pseudo-static experiments had been conducted. The ANSYS software was used to simulate the nonlinear behavior of the experimental specimens under the cyclic loading. The results obtained from the finite element analysis and the experiments demonstrated that the connections have good strength, stiffness , ductility and stable hysteric behavior.
