     this study is aimed at proposing a simple analytical model to investigate the post-cracking behaviour of frc panels, using an arbitrary tension softening, stress crack opening diagram, as the input. a new relationship that links the crack opening to the panel deflection is proposed. due to the stochastic nature of material properties, the random fibre distribution, and other uncertainties that are involved in concrete mix, this relationship is developed from the analysis of beams having the same thickness using the monte carlo simulation (mcs) technique. the softening diagrams obtained from direct tensile tests are used as the input for the calculation, in a deterministic way, of the mean load displacement response of round panels. a good agreement is found between the model predictions and the experimental results.
