【摘要】 通过对开洞砖砌体进行的拟静力试验,以泥浆砌筑的北京地区典型农宅的前纵墙作为研究对象,设计了3片采用不同加固措施的开洞墙体.从破坏情况、极限荷载与开裂位移等方面对3片墙体进行了对比分析,得出开洞墙体抗震的薄弱环节.并对钢丝网水泥砂浆加固和钢窗框加固两种方法的加固和增加效果及破坏特征进行了分析,提出了两种加固方式的加固建议.更多还原

【Abstract】 Considering the front longitudinal wall of rural housing built by mud masonry as an object of study,three windowed walls reinforced by different methods are designed through the quasi-static test of windowed brick masonry.These three walls are analyzed from the aspects which include destruction,ultimate load and cracking displacement,and the weaknesses of windowed walls are summarized in the earthquake.At the same time,the reinforcement effects and damage characteristics are analyzed for the steel mesh and cement mortar reinforcement and the steel sash reinforcement.In addition,reinforcement recommendations about two reinforcement methods are proposed.更多还原
