摘　　要：钢框架-钢板混凝土组合墙结构是一种适用于高层钢结构住宅的新型结构体系,目前国内规范还未对该体系进行相关规定。为研究该结构体系的抗震性能,以某高层住宅项目为例,建立了钢框架-钢板混凝土组合墙结构数值模型,采用静力弹塑性方法对该结构大震下的抗震性能进行分析。结果表明:该结构在整体与构件层次均满足抗震性能目标的要求;框架柱剪力分担率随结构塑性的发展而提高,结构塑性发展顺序符合预期,具有多道抗震防线;组合墙抗剪能力有较大富余,框架柱少量进入塑性状态。Steel frame-steel and concrete composite wall structure is a new type of structural system suitable for high-rise steel structure residences.At present,no relevant provisions for this system have been specified in domestic codes.In order to study the seismic performance of this structural system,a numerical model of steel frame-steel and concrete composite wall structure was established as an example for a high-rise residential project,and the seismic performance of this structure under rarely occurred earthquake was analyzed using the static elastoplastic method.The results show that the structure meets the requirements of seismic performance objectives at both the structure and component levels;the shear forces shared by frame columns increases with the development of structural plasticity,and the sequence of structural plasticity development is as expected,with multiple seismic defense lines;the composite wall has a large surplus of shear resistance,and the frame columns enter the plastic state in small amounts.
