摘要: 钢管混凝土柱由于其优越的力学性能而在工程中得到了广泛的应用‚但是其节点的研究显得还不够完整和充分.本文中研究了2个钢管混凝土加强环式梁柱节点的力学行为‚分析了梁、钢管壁和加强环的应变分布规律.试件均采用钢梁‚并采用构造不同的环间加劲肋.试验结果表明‚钢管混凝土加强环式节点力学性能良好‚节点刚度大;环间加劲肋的构造对节点的受力性能影响不大;加劲肋可以看作加强环梁的弹性支座‚可有效地降低环梁的跨度.

Abstract: The mechanics behaviors of two joints of a concrete-filled steel tubular (CFST) column-beam with ring stiffeners were investigated‚and the strain distributions of the beam‚the steel tube shell and the ring stiffener were also analyzed.The specimens are all steel beams with different stiffener ribs among the rings.The experimental results show that the joints of this column-beam are characterized by their excellent mechanics perfor mance and high stiffness‚that the construction of stiffener ribs have little influence on their mechanics behaviors‚and that the ribs can be regarded as elastic supports of the tubular beam with ring stiffeners‚which effec-
tively reduces the span of the hoop-beams.

Key words: concrete-filled steel tubular column, joint, ring stiffener, mechanics performance
