摘　　要：提出了一种装配式H型钢柱框架-复合墙抗震结构。为研究结构的抗震性能,进行了1榀足尺装配式H型钢柱框架与1榀足尺装配式H型钢柱框架-复合墙试件的低周反复荷载试验。对比分析了各试件的强度、刚度、延性、滞回特性、耗能能力及破坏特征。研究表明:内嵌复合墙破坏时被分割成多条条型复合墙板,在弹塑性变形后期对框架的支撑作用较为稳定;内嵌复合墙使框架的极限承载力提高了68%,使框架的初始刚度提高了394%;H型钢柱框架-复合墙试件的滞回曲线饱满,未出现捏拢现象;条型复合墙板企口连接的水平条带存在往复咬合错动,对结构耗能能力的提升有明显贡献。A seismic structure named assembled H-shaped steel column frame infilled with composite wall is proposed.In order to investigate the seismic performance of structure,a full-scale assembled H-shaped steel column frame and a full-scale assembled H-shaped steel column frame infilled with composite wall under reversed cyclic loading were tested.The strength,stiffness,ductility,hysteresis characteristics,energy dissipation capacity and failure characteristics of each specimens were compared and analyzed.The research shows that when it is broken the embedded composite wall is divided into multiple strips of composite wallboards and the supporting effect on the frame is stable in the late period of elastic-plastic deformation.The ultimate bearing capacity of the frame is increased by 68%and the initial stiffness of the frame is increased by 394%because of the embedded composite wall.The hysteresis curves of H-shaped steel column frame infilled with composite wall are full and the pinching phenomenon does not occur.The horizontal slip of the embedded strip-type composite wallboard is generated and because of that the energy dissipation of the structure is improved significantly.
