Experimental Research and Nonlinear Finite Element Analysis of CFRP-Strengthened High-Strength Concrete Structure



The debonding behavior at the interface between fiber-reinforced plastic (FRP) sheet and concrete is a key problem for the application of FRP plate, which has been widely applied in the civil engineering for rehabilitation and retrofitting of conventional structures. This paper presents the experimental and nonlinear finite element analysis results of the CFRP-strengthened high-strength concrete member. On the basis of the test, considering of the adhesive layer, explicit finite element is used for simulating the shear failure of CFRP-strengthened concrete, obtain the whole process of structure deformation development, describe the conformation and development of crack and the failure mode. The FE result coincides with the experimental result.
