A discrete-cracking numerical model for the in-plane behavior of FRCM strengthened masonry panels

Abstract In this paper, the structural behavior of masonry panels strengthened with a system made up composite fiber grids embedded in cementitious matrix (FRCM) is presented. The non-linear unreinforced and reinforced numerically simulated by means simplified micro-modelling approach. This approach concentrates all non-linearities failures joints potential crack surfaces within bricks, placed vertically middle each brick. FRCM strengthening discretized continuous bi-directional grid constituted trusses into matrix. A calibrated bond-slip relationship applied between fibers mortar assuming an idealized bilinear law. typical experimental load–displacement curve for panel shows three principal phases that correspond to different failure mechanisms: cracking, cracking ultimate panel. numerical analyses show good agreement results modeling found be adequate reproduce described behavior. parametric study on both material geometrical properties are also
