摘　　要：对7个高强螺栓外伸式端板连接的蜂窝钢梁-复合焊接环式箍筋混凝土柱组合节点试件进行低周反复加载试验,分析组合节点在模拟地震作用下的破坏形态和抗震性能,研究地震作用下组合节点合理螺栓布置形式,结果表明:相同的螺栓布置形式,螺栓直径大的其抗震受剪承载力高;不同的螺栓布置形式,螺栓尽量靠近梁翼缘的布置形式(3行3列)的节点是外伸式端板连接型钢-混凝土组合节点更为合理的节点形式.The low frequency cyclic loading tests on 7 composite joints specimens of cellular steel beam and welded compound-ring-hooped concrete column connected by extended end-plate with high-strength bolts were carried out to investigate the failure mode and seismic behavior of composite joints under simulated seism action, intends to put forward a reasonable bolts arrangement in composite joints under seism action. On the basis of test observation and analysis results, the conclusion can be drawn that with the same ar- rangement of bolts, the greater the bolt diameter is, the higher its seismic and shear capability would be; Among different types of arrangement for bolts, joints in which the bolts are arranged as close as possible to the beam flange （three rows and three columns） are the more reasonable ones among steel-concrete corn- posite joints of extended end-plate connection.
