To　research　the　mechanical　behavior　of　concrete　members　strengthened　by　CFRP　sheets　bonded　with　an　organic　adhesive,　three　unbonded　prestressed　concrete　two-span　continuous　beams　after　bending　test　were　strengthened　with　CFRP　sheets　bonded　with　the　organic　epoxy　adhesives.　Test　on　the　flexural　behavior　of　the　strengthened　beams　was　carried　out.　The　tested　data　of　curve　of　load-deflection　at　mid-span　and　bending　moment　capacity　of　the　strengthened　beams　were　obtained.　The　failure　mode　is　that　the　tensile　longitudinal　steel　bars　yield　first,　then　CFRP　sheets　break　in　tension.　Experimental　results　showed　that　the　flexural　behavior　of　damaged　prestressed　concrete　continuous　beams　can　be　improved　significantly　by　strengthening　with　CFRP　sheets　bonded　with　the　inorganic　adhesives.　Computational　method　of　stiffness　and　normal　section　load-bearing　capacity　of　the　prestressed　concrete　continuous　beams　after　bending　test　strengthened　with　CFRP　sheets　bonded　with　inorganic　adhesive.　The　calculated　result　is　in　good　agreement　with　testing　data.　©,　2014,　Wuhan　University　of　Technology.　All　right　reserved.
