[提要] 钢梁-钢筋混凝土柱节点是钢-混凝土框架结构的主要传力部件,认识节点的受力性能对结构设计是至关重要的。通过四个受反复荷载作用,轴压比、节点构造和截面尺寸不同的钢梁-钢筋混凝土柱节点的试验,研究了节点的强度和变形性能。通过试验研究,使我们对钢梁-钢筋混凝土柱节点在反复荷载作用下的力学性能有了初步的认识。
[关键词] 组合结构 节点 反复荷载 钢梁 混凝土柱The mechanical characteristic of the joint of the steel beam-reinforced concrete column has scarcely been studied at home. As the main transfer of the force of the frame structure, the joint takes the important role in the steel-concrete composite structure. Four steel beam-reinforced concrete column joints are tested under the reversed loading. The axial compression ratio, the climension of the reinforced concrete column and the construction of the joint are examined.
Keywords: composite structure; joint; reversed load; steel beam; reinforced concrete column
