FRP作为一种新型高性能材料,由于其可以增加构件的强度和延性,近年来在土木工程中应用广泛,尤其适用于结构抗震加固.目前,国内外对FRP约束混凝土柱的研究主要集中于单向荷载作用,而对反复荷载作用下的研究相对较少,因此对反复荷载作用下FRP约束混凝土的受压性能进行更加深入的研究具有重要的理论意义和工程实践价值.总结了国内外学者关于FRP约束素混凝土柱和钢筋混凝土柱在反复荷载作用下受压性能的研究成果,得出了以下结论:①单向荷载作用下的应力-应变曲线可以作为反复荷载下的包络线;②反复加卸载会造成应力损失,唯一性理论不成立;③FRP布的约束效果随着截面尺寸的增加而减小.最后对今后拟开展的研究工作提出了建议与展望.
