The hysteretic loop, skeleton curve, failure mode and ductility were analyzed. The results show that the hysteretic loop is in a plump-shape, and energy dissipation capacity of the connection is well. Finite element analysis by software of ABAQUS was used to simulate the property of the specimen under low cyclic loading. The calculation results agreed with the test results very well. Based on the test results, parametric analysis of the connection was carried out. The results show that the volume of steel web has a great impact on the bearing capacity of the connection. The yield load and ultimate load of the connection increase with the increment of the steel web volume in an linearity relationship approximately.Keywords:hybrid coupled wall; steel coupling beam; quasi-static test; finite element analysis; bond-slip*国家自然科学基金资助项目(50878182)，陕西省自然科学基金项目（SJ08E209）。作者简介：宋安良，博士，Email:allsong1985@163.com。参考文献［1］宋安良，苏明周，王振山，等.新型混合联肢墙节点恢复力模型试验研究［Ｊ］．建筑结构，2015，45（3）：21-26.［2］白国良，秦福华．型钢钢筋混凝土原理与设计［M］．上海：上海科学技术出版社，2000．［3］潘建荣, 王湛, 张吉. 框架组合梁柱节点的非线性有限元分析［J］. 西安建筑科技大学学报：自然科学版, 2009, 21(5): 655-662.［4］JGJ 99—98高层民用建筑钢结构技术规程［S］. 北京: 中国建筑工业出版社, 1998.［5］刘义．型钢混凝土异形柱框架节点抗震性能及设计方法研究［D］．西安：西安建筑科技大学，2009．［6］张劲, 王庆杨.
