摘　　要：全国校安工程开展后,大量教学楼迫切需要进行抗震加固。结合砌体教学楼特点以及纵墙受力情况,探讨了组合墙板加固砌体纵墙的可行性,结果表明组合墙板抗剪承载力可以满足要求。采用MIDAS有限元软件分析,得到了不同连接方式对组合墙板加固窗间墙效果的影响规律,确定了最优加固连接方式。考虑快速、便捷以及原有结构的不利影响,提出了通过组合墙板内置预埋件、原结构加设后埋件,通过两者间的有效连接实现与原结构的可靠连接,并给出了满足快速加固要求的节点构造。Since the practice of school safety program has been carried out widely all over China,lots of classroom buildings need to be reinforced. The Feasibility of composite panel reinforcing longitudinal wall of masonry classroom was analyzed, considering masonry building feature and force condition of longitudinal wall. The result showed composite panel had enough capacity to reinforce masonry building. The influence of different joints on the effect of composite panel reinforcing wall between windows was analyzed with MIDAS software. Considering rapid construction, convenience and adverse effect of the original structure, the connection was proposed. The new composite panel was connected with original wall effectively through embedded plate in them. And construction of connection joint was proposed to realize rapid reinforcement.
