【摘要】 为了研究蜂窝钢梁—焊接环式箍筋混凝土柱节点的抗震性能,对4种不同连接形式的蜂窝钢梁—焊接环式箍筋混凝土柱的梁柱节点试件进行低周反复加载的拟静力试验,分析了其节点在模拟地震作用下的破坏形态、承载力、延性、滞回特性等,初步探讨了蜂窝钢梁—焊接环式箍筋混凝土柱的抗震性能.试验结果表明:合理的蜂窝钢梁—焊接环式箍筋混凝土柱节点能满足抗震工程实践要求,并通过不同连接形式节点的受力性能分析对比,最终得出符合抗震设计要求的组合节点连接形式.更多还原

【Abstract】 The mechanical behavior of the honeycomb steel beam-welding ring stirrups concrete column joints is studied.Four different types connecting joints were tested through the pseudo static tests under low cyclic reversed loads.The failure modes,bearing capacity,ductility and the hysteretic behavior of the joints under seismic loads were researched.Meanwhile the seismic behavior of the joints was investigated initially.The tests show that the reasonable honeycomb steel beam-welding ring stirrups concrete column joints can meet the requirement of engineering practice for earthquake resistance.And through comparison analysis of joints in different styles of connection,the composite joint satisfying the demands for seismic design is obtained.更多还原
