摘　　要：通过5个1/2缩尺试件在高轴压比下的低周反复加载试验,研究了型钢混凝土柱-钢梁框架中部节点的破坏形态和受力性能,讨论了节点核心区配箍率低于规范要求配箍率的可行性,并对现行规范公式提出了修改建议。With 5 one-second scale joint specimens tested under monotonic and cyclic loadings with high axial compression ratio,failure characteristics and mechanical properties of steel reinforced concrete column-steel beam joints( SRC) were studied. The SRC joint has better ductility and load capacity; the cracking load and ultimate bearing capacity were improved,the energy dissipation raises,and the brittle fracture was avoided.

关 键 词：型钢混凝土 节点 受力性能 轴压比 配箍率
