Strut-and-tie model for a reinforced concrete wall strengthened with carbon fibre-reinforced polymers

This study describes a nonlinear truss modelling approach for a reinforced concrete (RC) wall strengthened with carbon fibre-reinforced polymers (CFRP) subjected to a lateral displacement load test. Nonlinear vertical and diagonal truss elements are used to represent the reinforcement and the concrete. The model is developed based on a truss analysis of the RC strut and tie model. The capability of the model is demonstrated by comparing the measured and computed load response behaviours of non-strengthened RC walls and RC walls strengthened externally with CFRP.
