N2 - The use of fibre reinforced plastic (FRP) has gained particular attention for strengthening and upgrading of existing civil engineering structural elements. In this paper, the LUSAS-FEA finite element software has been used to study the non-linear behaviour of reinforced concrete beams externally strengthened with carbon fibre reinforced polymer (CFRP) composites under static loading. For validation purposes the finite element results were compared with the experimental load deflection curves and ultimate failure load results reported in the literature. The concrete was modelled using a multi crack 2D plane stress element. A bar element was used to model the reinforcement bars and CFRP. In this study, the bonding between the concrete and the CFRP was modelled using two assumptions; either (1) multi-crack model, or (2) a Drucker-Parger model. Satisfactory agreement between the finite element analysis and the experimental results was observed in terms of the load deflection curve, the crack pattern, the failure load and the mode of the failure. © 2013, NetComposite Limited.
