Abstract

The aims of this paper are firstly to evaluate and to model the delamination characteristic of FRP sheet bonded on RC beam, and then to propose the evaluation methodlogy of constitutive law for the bond of sheet and finally to verify the applicability of the proposed method to smeared crack type FEM analysis. As a result, the follwing conclusions were obtained. The delamination of FRP sheet is generated by local yield of steel reinforcement near the loading point. The effective bond development length of RC beam is larger than that of the bond test specimen due to the effect of curvatureof the beam by bending. The bond consitutive law can be evaluated considering the difference of effective bond development length and can be applied to the smeared crack type FEM analysis.
