FAILURE PROCESS IN RC BEAMS SHEAR-STRENGTHENED WITH FRP IN HOGGING MOMENT ZONE
RC beams shear-strengthened with externally bonded FRP usually fail in shear either by FRP debonding or by FRP rupture.The failure processes of the beams with different strengthening configurations and subjected to different load conditions are different.Following our previous analytical study on progressive failure in RC beams shear-strengthened with FRP strips in sagging moment zone,this paper presents an analytical study on the failure processes in RC beams shearstrengthened with FRP in hogging moment zone.Next,the closed-formed solution for complete debonding failure process is presented first,based on which the contribution of the shearstrengthening FRP to the shear capacity of the beam is quantified.The validity of the analytical solution was verified by comparing its predictions with the numerical results from a finite element analysis.
