Abstract

A simple analytical model that can easily be implemented in MATLAB (Matrix Laboratory) is presented for accurately predicting the moment-curvature and load-deflection relations of concrete beams reinforced with internal tensile steel bars and rehabilitated with externally bonded carbon fibre reinforced polymer (CFRP) strips. The model has been verified by comparing model results with those obtained experimentally. The model results and test data show that, with adequate bond strength, application of a CFRP strip to a reinforced concrete beam significantly increases the capacity. Currently, the model does not consider debonding failure of CFRP from the beam.
