针对全钢筋混凝土框支剪力墙在工程中所存在的问题,提出了采用比强度高、耐腐蚀性能好、自重轻但弹性模量低并具有线弹性性能的纤维增强塑料(FRP)筋来替换该剪力墙中部分钢筋的建议.通过拟静力试验及非线性有限元数值分析,比较了1榀全钢筋混凝土框支剪力墙试件(FSW-1)和1榀部分配置FRP筋框支剪力墙试件(FSW-4)的裂缝发展规律和破坏模式,及其承载能力、延性性能和滞回特征.结果表明:部分配置FRP筋框支剪力墙结构具有较高的承载能力和较好的抗震性能;非线性有限元分析结果与试验结果吻合较好.
In view of the existing problems of the RC frame-supported shear walls in engineering, a fiber reinforced plastic (FRP) with high specific strength, good corrosion resistance, light weight but low elastic modulus and linear elasticity is proposed And to replace some of the reinforcement in the shear wall.Analyzed by quasi-static test and nonlinear finite element numerical analysis, 1 × RCF framed shear wall specimen (FSW-1) and 1 × part of FRP reinforcement The crack development regularity and failure mode of the frame-supported shear wall specimen (FSW-4), as well as its bearing capacity, ductility and hysteretic characteristics are studied.The results show that the FRP- Capability and better seismic performance. The results of nonlinear finite element analysis are in good agreement with the experimental results.
