AbstractDebonding is the prevailing failure mode in the retrofitted RC beam using carbon fibre-reinforced polymer (CFRP). Therefore, this issue should be given more concern. A non-linear 3D numerical model was used to study the effects of different parameters on the failure mechanisms and load capacity of retrofitted beam by CFRP. These parameters were: internal tensile reinforcement, internal shear reinforcement, pre-crack number and beam width. In addition, this paper deals with the effect of mesh sensitivity on modelling retrofitted beam behaviour. The non-linear behaviours of concrete, steel and the interface between concrete and CFRP were taken into consideration. It was found that mesh sensitivity plays a role in representing the behaviour of retrofitted beam with CFRP. The results indicate that internal tensile reinforcement, internal shear reinforcement, pre-crack number and beam width have significant effects on the percentage of load increase and strain in CFRP.
