Research status of dynamic responses of RC structure confined with FRP under blast loading

Fiber reinforced polymer (FRP) has been widely used in civil engineering with the advantages,such as high strength to weight ratios,corrosion resistance,fatigue resistance,low thermal conductivity and so on.This study focuses on the blast resistance of the reinforced concrete (RC) structure confined with FRP.By reviewing the research on the dynamic responses of the reinforced structure confined with FRP under blast loads,it is found that the blast resistance of RC structure has been significantly strengthened by the confinement of FRP.Additionally,primary results are introduced from the three aspects,such as the theoretical research,experimental research and numerical analysis.Based on the existing achievements,both valuable research issues and suggestions are presented,which could provide a certain reference for the future research.
