摘　　要：采用有限元软件ANSYS,对钢骨-钢管C60混凝土梁柱节点和圆钢管-钢骨水泥聚丙烯纤维(简称PP ECC)节点进行三维非线性有限元分析。分析结果表明,由于PP ECC的作用,普通圆钢管-钢骨混凝土梁柱节点的极限承载力远小于圆钢管-钢骨PP ECC梁柱节点的极限承载力,充分体现了PP ECC良好的刚度及承载力。同时也表明,PP ECC比普通混凝土能更好地同钢管、钢骨协同工作,更能充分发挥钢管、钢骨的受力性能。By ANSYS software a three-dimensional nonlinear finite element analysis was made to steel tube filled with steel-reinforced C60 concrete beam-column joints and circular steel tube filled with steel-reinforced PP ECC joints. Analysis results show that due to the role of the PP ECC, ultimate bearing capacity of the ordinary circular steel tube filled with steel-reinforced concrete beam-column joints is far less than the ultimate bearing capacity of circular steel tube filled with steel-reinforced PP ECC beam-column joints. Which fully reflects the stiffness and bearing capacity of the PP ECC. PP ECC can better collaborative work with steel tube filled with SRC than normal concrete and play the mechanical properties of steel tube filled with SRC.
