Some　primary　achievements　about　technology　of　strengthening　RC　structures　with　prestressed　aramid　fiber　reinforced　polymer　(AFRP)　sheets　and　carbon　fiber　reinforced　polymer　(CFRP)　bars　are　introduced,　including　the　research　on　permanent　anchors　for　prestressed　AFRP　sheets,　on　stress　relaxation　of　the　prestressed　AFRP　sheets,　on　flexural　and　shear　behavior　of　RC　beams　strengthened　with　prestressed　AFRP　sheets,　on　the　effect　of　temperatures　on　the　mechanical　properties　of　adhesives　for　AFRP　sheet,　on　mechanics　behavior　of　concrete　beams　locally　strengthened　with　external　CFRP　bars,　on　seismic　performance　of　macro-fiber　concrete　beams　strengthened　with　prestressed　CFRP　bars,　and　on　engineering　application　of　strengthening　RC　structure　with　prestressed　FRP　sheets.
