摘　　要：内隔板式节点是应用较广的钢管混凝土柱节点形式之一,现在被广泛应用在多层建筑,高层建筑等相关领域.本文结合实际工程经验,取多层框架结构中的边跨节点JD-1,JD-2和JD-3内隔板式矩形钢管混凝土柱-H型钢梁节点,进行低周往复荷载试验,对存在空鼓的矩形钢管混凝土柱边跨节点进行承载能力与抗震性能试验研究,探讨了空鼓占比因素对节点承载性能和抗震性能的影响.Inner partition joints are one of the more widely used forms of concrete-filled steel tubular column joints.They are now widely used in related fields such as multi-storey buildings and high-rise buildings.Based on the actual engineering experience,this paper took the side-span joints JD-1,JD-2,and JD-3 in the multi-layer frame structure and adopted the inner-separated rectangular concrete-filled steel tubular column-H-shaped steel beam joints to conduct low-cycle reciprocating load tests.Experimental research on the bearing capacity and seismic performance of rectangular steel tubular concrete columns with empty drums was conducted,and the influence of the proportion of empty drums on the bearing capacity and seismic performance of the joints was discussed.

关 键 词：钢管混凝土 空鼓占比 承载能力 抗震性能
