摘　　要：采用有限元分析软件ANSYS,对钢梁-方钢管内置C60混凝土和聚丙烯纤维增强水泥基复合材料(PP ECC)梁柱节点进行了三维非线性有限元分析。分析结果表明:由于PP ECC的作用,钢梁-方钢管钢骨PP ECC梁柱节点的极限承载力远大于钢梁-方钢管钢骨混凝土梁柱节点的极限承载力,充分体现出PP ECC具有良好的刚度及承载力。PP ECC比混凝土能更好地与钢管、钢骨进行协同工作,更能充分发挥钢管、钢骨的受力性能。The finite element software ANSYS has been employed, three-dimensional nonlinear finite element analysis has been made on steel ribs-steel pipe C60 concrete beam-column connections and circular steel tubesteel ribs PP ECC connection. It shows that due to the role of PP ECC, the ultimate bearing capacity of the beam column connections o[ the square steel tube-steel ribs PP ECC is much more than the ultimate bearing capacity of ordinary square steel tube-steel ribs concrete beam-column connections, which fully embodies the good stiffness and load bearing capacity of PP ECC. Compared with ordinary concrete, PP ECC can do better than steel tube steel ribs collaborative work. It can fully play the role of the mechanical behavior of steel tube-steel ribs.
