摘要
用混凝土板墙加固砖墙,并分别将对比用墙片和加固后墙片进行低周反复荷载作用下的试验研究。通过与未加固砖墙的对比,分析了用混凝土板墙加固砖墙的效果及抗震性能,分别给出单面板墙加固和双面板墙加固墙片的强度提高系数及刚度提高系数;通过与140mm厚混凝土剪力墙的比较,分析将加固后墙片作为剪力墙看待的可行性以及加固后墙片对砌体结构体系改变的影响。
A series of low-cycle repeated loads experiments and analysis on ordinary brick walls and brick wall strengthening with concrete splint are introduced.Comparing with the brick walls unreinforced,the walls＇performance to resist earthquake is analyzed.Then,the strength coefficient and stiffness coefficient about the brick wall strengthening with concrete splint are given.Comparing with the concrete shear wall,the feasibility of the view that we can make the brick wall strengthening with concrete splint as the concrete shear wall is analyzed in this paper.
