Abstract

New retrofitting techniques using carbon fibers are presented. For existing reinforced concrete columns, a CFRP winding technique is employed, in which carbon fiber strands or sheets are wound onto the surface of columns, impregnating and curing epoxy resin. The additional CFRP hoops are constructed to make the columns more ductile. However, debonding of CFRP from a concrete surface limits applications of these CFRP techniques for other retrofit works. From experimental and analytical research, debonding strength and effective bond length are found.
