A lattice model is proposed to study the mechanics of pultruded FRP elements. Special attention is devoted to the modeling of crack propagation on the web-flange junction of a pultruded GFRP profile which is subject to a localized pullout force. The proposed numerical model discretizes the beam into rigid blocks interconnected by 1D elements. The work presents: 1) the adopted strategy for the model formulation; 2) the definition of mesoscale constitutive laws and their scaling to preserve correct energy dissipation; 3) a multiscale experimental investigation devoted to the identification of the mesoscale properties of the 1D lattice elements; 4) concluding remarks and directions for future research.
