摘　　要：为了探讨蜂窝状钢骨混凝土T形柱-钢梁节点的受力与变形特性,进行典型强、弱2组节点的单调加载试验和非线性分析,考察轴压比、配箍率、混凝土强度等主要参数对节点承载力的影响。结果表明:强、弱节点的破坏模式分别为梁铰失效模式和剪切失效模式;强节点的承载力主要由钢梁尺寸和钢材强度决定,弱节点的承载力主要由配箍率、混凝土强度、节点区型钢腹板强度和高厚比决定。To investigate the stress and deformation characteristics of joints for T-shaped honeycombed steel reinforced concrete columns and steel beams,monotonous loading experiments and finite element analysis on two groups of typical joints were conducted.The effects of the parameters,such as axial compression ratio,hooped stirrup ratio,concrete strength and so on,on the joint carrying load were investigated.Results showed that the failure mode of strong-joint was beam failure,and that of weak-joint was shear failure.The carrying load of the strong joint is mainly dependent on the size of steel beam and steel strength.However,the carrying load of week joint was very much dependent on hooped stirrup ratio,concrete strength,the strength,and the height-thickness ratio of the steel-web.
