［摘要］針對空斗墻加固中造價高、工期長、施工工序復雜等問題，提出了應用BFRP加固技術，BFRP加固空斗墻具有施工簡單、造價低、抗震效果好等特點。通過6片低強度空斗墻水平低周反復荷載試驗，包括2種不同的砌筑方式（全空斗、三斗一眠）和3種不同的BFRP加固方式，分析了加固前后各試件的破壞形態(tài)、抗剪承載力、滯回曲線、骨架曲線、延性和墻體的剛度及剛度退化曲線。試驗結(jié)果表明：三斗一眠的空斗墻的抗震性能優(yōu)于全空斗墻，低強度空斗墻經(jīng)過BFRP加固后承載力在一定程度上得到了增強，延性系數(shù)變大，變形增加，剛度退化速度變慢，抗震性能得到提升，其中以X形雙面剪刀撐加固方式效果最好。

Abstract:Aiming at the problems of high cost, long construction period and complex construction procedure in the reinforcement of the rowlock wall, it puts forward to adopt BFRP reinforcement technology. Reinforcement of rowlock wall with BFRP has the characteristics of simple construction, low cost and good seismic effect. The horizontal low cyclic loading tests were conducted on 6 pieces of low strength rowlock wall, including 2 kinds of masonry measures (full rowlock and partly rowlock) and 3 different BFRP reinforcement measures. The failure modes, shear capacity, hysteretic curves, skeleton curves, ductility and wall stiffness and stiffness degradation curve of each specimen were analyzed for conditions before and after the reinforcement. The test results show that: partly rowlock wall has better seismic performance than the full rowlock wall. Bearing capacity of low strength rowlock wall is enhanced to a certain extent after BFRP reinforcement, and the ductility coefficient increases and deformation increases, stiffness degradation slows down, and the seismic performance is improved. X-typed double-sided scissor-bracing reinforcement effect is the best.
Keywords:rowlock wall; basalt fibres reinforced polymer(BFRP); full rowlock; partly rowlak; seismic performance
