Fabric Reinforced Cementitious Matrix (FRCM) composites are widely seen as offering advantages in structural retrofitting of existing buildings. In spite of their reputed effectiveness, FRCM systems typically suffers from several drawbacks related to the mechanical characterization due to complex stress transfer mechanicisms that can develop at fiber-matrix and FRCM-substrate interface. Numerous experimental studies focus on this topic, but few numerical studies are addressed to better understand the variables involved in the problem. This paper aims to propose a simple 1D numerical model to predict the shear bond behaviour of FRCM applied on concrete substrate, providing support to deduce reliable criteria for design procedures.
