Two mathematical approaches have been developed to predict the uniaxial stress-strain behaviour of textile reinforced concrete (TRC). In the first approach micro and meso mechanical principles have been used and bond stress-slip relation of textile reinforcement is considered as the basis for the development of model. In the second approach, laminate theory is coupled with damage mechanics concepts to simulate the stress-strain behaviour. A continuum damage model has been developed to account for the distributed cracking using a scalar damage function and damage equations are developed to address the stiffness reduction. The stress-strain behaviour from the two models have been compared and validated with experimental results.
