摘要
为研究钢框架-装配式混凝土抗侧力墙结构体系(SPW体系)的抗震性能,对2榀足尺钢框架-预制钢筋混凝土抗侧力墙结构进行低周反复荷载作用下的试验,研究结构的破坏形态、滞回性能、延性及变形以及耗能性能等。试验结果表明:该结构体系为一种典型的双重抗侧力体系,加载过程呈现出明显的两阶段受力状态,抗侧力墙作为结构抗震的第一道防线,在加载前期承担主要的水平荷载,随着墙体退出工作,钢框架成为结构抗震的第二道防线;加载后期,由于抗侧力墙顶部连接发生破坏,钢框架承担所有的水平剪力和倾覆弯矩作用。
In order to research the seismic behavior of steel frame-concrete lateral force resisting wall fabricated structures,two full scale specimens composed of steel frame and reinforced concrete lateral force resisting wall were tested under cyclic horizontal loading,and the failure mode,hysteretic behavior,ductility and deformation and energy dissipation were investigated. Experimental results show that the structure is a typical double lateral force resisting system. As the first line of defense for the structural system,the concrete lateral force resisting wall shares the main lateral load at the early loading stage,and steel frame is the second line of defense for the structural system after the concrete lateral force resisting wall is out of work,and at the later loading stage,steel frame shares all of the lateral load and overall overturning moment because of the connection damage of concrete lateral force resisting wall at its top position.
