摘要

为研究碳纤维布对低强度砖砌体墙片的加固效果,采用1个对比试件,2个加固试件,进行碳纤维布加固低强度有构造柱带侧门洞墙片在低周期往复荷载作用下的抗震性能试验,对加固后墙片的破坏形态、变形性能、耗能能力及承载力作了全面分析,结果表明碳纤维布用于低强度砖砌体墙片的抗震加固是有效的.并探讨了碳纤维布加固有构造柱带侧门洞墙片时的受力机理,分析加固后墙片的抗剪承载力,提出简化计算公式,可为加固工程的设计提供参考.
In order to study the effect in using carbon fiber sheet(CFS) to strengthen low strength masonry,the seismic reinforcement experiment of low strength brick wall with constructional columns and a side door by carbon fiber sheet is done under lower cycle reversal loads based on one contrastive wall and two strengthened walls.The strengthened brick wall's failure shape,deformation,energy consumption and load bearing capacity are generally analyzed,and the results show that the strengthening effect is obvious.Then CFS's bearing capacity and the wall's shearing capacity are analyzed,and the simplified calculating formula is presented,which provides the reference for the design.
