摘　　要：纤维增强复合材料对混凝土构件的受弯、受压及受剪的加固研究已经比较成熟,但针对纤维增强复合材料加固钢筋混凝土构件的扭转问题的研究还不多,目前规范中对于混凝土构件的抗扭加固也很少涉及。回顾和总结了纤维增强复合材料抗扭加固钢筋混凝土构件的研究现状,从粘贴形式和锚固方法两个方面归纳了抗扭加固方式;从原梁条件和加固参数两大项研究分析抗扭加固效果;探讨了纤维增强复合材料加固钢筋混凝土构件的抗扭机理和破坏模式并归纳总结了纤维增强复合材料加固钢筋混凝土受扭构件的承载力计算方法;分析总结了纤维增强复合材料加固钢筋混凝土受扭构件研究尚存的不足并对将来的发展趋势进行展望,为今后混凝土结构受扭加固项目提供方法借鉴,也为将来制定技术规范的修订提供研究资料和参考建议。Concrete members strengthened under bending,compression and shear with fiber reinforced plastics has been relatively mature.However,there are not many studies on concrete members strengthened under torsion with fiber reinforced plastics.The current specifications for concrete members strengthened under torsion with fiber reinforced plastics is also rarely involved.It reviews and summarizes the research status of concrete members with fiber reinforced plastics,and summarizes methods of torsion strengthening,including paste forms and anchoring methods.It analyzes the effect of torsion strengthening from two major aspects of original beam conditions and strengthening parameters.The torsion mechanism and failure modes of concrete members strengthened with fiber reinforced plastics are discussed,and calculation methods for the bearing capacity of concrete members strengthened under torsion with fiber reinforced plastics are summarized.It analyzes and summarizes remaining deficiencies in the research on concrete members strengthened under torsion with fiber reinforced plastics and prospects for future development trends,providing a reference for future torsion strengthening projects of concrete structures,and also providing research data for future revision of technical specifications and reference suggestions.
