| Abstract: | Based on the linear elastic theory,this paper presents a method for calculating the peeling stress at the sheeting end of a RC beam with a strengthening under linear distributed loads.And introduced the phenomenon about debonded failure of RC flexure members strengthened with carbon fiber sheets(CFSs).The main factors influencing debonded failure have been concluded.Finally,engineering measurements to prevent debonded failure have been advised. |
