Nonlinear FE Model of the CFRP / Concrete Interface

This paper presents a finite element analysis which is validated against laboratory tests of eight beams strengthened with externally bonded with carbon fibre reinforced plastic (CFRP) plates. The commercial numerical analysis tool Abaqus was used. Cohesive elements were used to model traction and shear behaviour of concrete/CFRP interface. The results are presented and discussed in terms of loading capacity. The results obtained from finite element models show good agreement with the experimental results.
