摘　　要：基于静态荷载作用下的纤维增强复合材料(Fiber reinforced polymer,FRP)加固钢筋混凝土梁式构件性能的研究已经开展得相当广泛。相反,冲击荷载作用下FRP对RC梁式构件的加固效果的认识急需提高。冲击荷载作用下RC构件性能的分析需要考虑多种动力学效应,如惯性效应、应变率效应。本文介绍了考虑应变率效应的FRP-混凝土界面动态行为方向的研究现状和冲击荷载作用下的FRP加固钢筋混凝土梁式构件的研究进展,并对值得进一步深入研究的问题进行了探讨与展望。Fiber reinforced polymer(FRP)reinforced concrete beams under static loading have been extensively studied.On the contrary,the understanding of the effect ofFRP on the strengthening effect of RC beam members under impact loading is in urgent need to improvement.Many dynamic effects such as inertial effect,strain rate effect need to be considered in the analysis of the performance of RC members under impact loading.In this paper,the research status of dynamic behavior direction of FRP-concrete interface with strain rate effect is introduced,and the research progress of FRP strengthened reinforced concrete beam members under impact load is introduced.Finally,the problems worthy of further study are discussed.
