摘　　要：为了实现轻钢龙骨内墙与主体钢框架梁的连接既能满足受力性能和物理性能的要求,又能体现预制装配式结构的特点,设计了轻钢龙骨内墙与主体钢梁连接、与地面连接新形式,并利用有限元软件对新型连接下的轻钢龙骨内墙平面外的受力性能进行模拟,分析其承载力、变形和应力变化情况。研究表明,新型连接下墙体的承载力满足CECS 261∶2009《钢结构住宅设计规范》规定,且能满足多遇地震下框架结构的弹性层间位移限值和罕遇地震下框架结构的弹塑性层间位移限值。In order to meet the requirements of mechanical and physical performance as well as reflecting the prefabricated characteristics of the connection,new-type connection structures between light steel keel interior wall and steel frame beam and floor were designed in this paper. The out-of-plane mechanical performance of light steel keel interior wall with the new type connection structures was simulated by using the finite element software. The bearing capacity,deformation and stress changes were analyzed. The results showed that the bearing capacity of the new connection could meet the provision of Code for Design of Steel Structure Residential Building（ CECS 261∶ 2009）. The new connections could accord with the limit value of elastic interlayer displacement of frame structure under frequent earthquake,as well as elastoplastic interlayer displacement under rare earthquake.
