摘　　要：通过含有钢筋混凝土连梁、钢连梁与新型组合钢连梁的结构进行试验对比,利用ANSYS软件建立试验模型,进行模拟试验分析,研究新型组合钢连梁在弹塑性状态下的抗震性能。试验结果表明,小跨高比连梁采用新型组合钢连梁,其抗震性能好,适宜剪力墙结构采用。To study the seismic behavior of a new type of composite coupling steel beam under elastoplastic stage, the test of models with a the traditional reinforced concrete coupling beams and the steel coupling beams and new type of composite steel coupling beams was carried out. The test models was firstly established with the use of the software of computer simulation analysis-ANSYS,then the effect of the coupling beams on elastic-plastic stage of the structural system was examined. The experimental results show that the high buildings with coupling beams of the small aspect ratio have good seismic performance if the composite steel coupling beams with control devices are installed on the middle floors of the structural system.
