中文摘要	RC环梁连接的钢管混凝土柱-RC梁框架在竖向荷载和水平荷载作用下,在环梁一定高度范围内,环梁与柱之间会有很窄的缝隙。通过有限元分析研究了环梁连接的转角刚度和环梁区域框架梁等效宽度以及它们的影响因素,结果表明环梁宽度和框架梁宽度对转角刚度和等效宽度影响较大。框架内力、位移计算以及两层两跨框架结构的静力试验和拟动力试验表明,环梁连接的钢管混凝土柱-RC梁框架可以采用梁柱直接刚性连接的模型进行弹性分析。; For the steel tube confined concrete (STCC) column-RC beam frame connected by reinforced concrete (RC) ring beam subjected to combined vertical and horizontal loads, there may be a very narrow gap between the ring beam and the column at certain height. The gap has influence on the frame stiffness. By finite element analysis (FEA) of the beam-column joints, the rotation stiffness and the equivalent beam width of the ring beam connector are examined, and the influence factors are investigated. It is found that the ring beam and the frame beam width have significant influence on the rotation stiffness and the equivalent width. Static and pseudo-dynamic tests on a two bay-two story STCC column-RC beam space frame with RC ring beam connectors have been performed. The test results are compared with the analysis results of a 3-bay 10-story frame. It is shown that treating the STCC column- RC beam as rigid joint is reasonable during the analysis of STCC column-RC beam frame connected by RC ring beam.
