A new orthotropic limit function is developed to describe the failure of masonry under in-plane loads. The formulation starts from the isotropic smooth 3D yield function proposed by Bigoni and Piccolroaz (2004) to provide a strength condition for masonry through a single analytical function including orthotropy and different tensile and compressive strengths. The material parameters are calibrated by means of a simple optimization procedure based on available experimental and numerical data. Finally, the limit function is implemented in a finite element code in the framework of a perfect plasticity, through a numerical procedure based on a predictor–corrector algorithm. The effectiveness of proposed model is verified through the comparison of numerical simulations with experimental data available in the literature.
