Abstract

Experimental and numerical results show that the predominant failure mode of FRP strengthened masonry structures is the interfacial debonding, which occurs prior to reaching the compressive strength of the substrate and/or the tensile strength of the FRP composite. In this paper, a three-dimensional numerical model is developed to simulate the experimental response of direct shear test applied to a FRP sheet on the masonry substrate. A damage model is adopted for both mortar and bricks characterized by different behavior in tension and compression.
