Limit equilibrium state for FRP reinforced masonry walls under in plane actions

In this work, a model for obtaining equilibrated and admissible stress states for FRP reinforced masonry walls in-plane loaded is proposed. In order to obtain the yield domains for the reinforced masonry, a 3D homogenization model is used. This model is based on a crucial choice of the constitutive functions for each constituent material. For the unreinforced masonry, the references are the yield domains obtained by means of both kinematic and static approaches, where the mortar may be assumed as a no tension or a frictional material. For the reinforcement, a simplified model with only tensile strength is used. The shear stresses transmitted by the reinforcement to the wall are either limited in order to prevent delamination phenomena or are assumed to vanish in presence of suitable anchoring systems.
