Considering the disadvantages of the traditional connections, combining with an engineering example, new column-beam composite joint and concrete wall-steel beam hinge joint have been designed. Experimental study on seismic performance of scale components was conducted, which showed that failure on beam ends was occurred and strong connection-weak component seismic requirements were achieved. Finite element analysis was accomplished to further grasp the force characteristics of the new joints. Moreover, influence factors on the bearing capacity of the new column-beam composite joint were studied through finite element analysis. The results indicate that the greatest impact on the bearing capacity of column-beam joints is the inner baffle, secondly the embedded T column. In condition of the same inner baffle, the depth of T column shows more obvious effect on the bearing capacity than the height of T column.Keywords: column-beam joint; concrete wall-steel beam joint; experiment; finite element analysis作者簡介：聶建國，教授，博士生導(dǎo)師，Email: niejg@mail.tsinghua.edu.cn。參考文獻［1］高立人. 梁-混凝土柱組合框架結(jié)構(gòu)國外的發(fā)展［J］. 建筑結(jié)構(gòu), 2002,32（5）：34-37.［2］GREGORY GDEIERLEIN, HIROSHI NOGUCHI.
