One of the ways that is conventional in the last two decades for seismic improvement and retrofit of concrete and masonry structures is using the various fiber reinforced polymers (FRP). Among the most important issues in reinforcement of masonry walls by FRP composites, there is debonding of FRP sheets from the surface of the wall. Therefore in the current study the effect of wall surface preparation methods on the bearing capacity and ductility of masonry walls strengthened with FRP sheets have been investigated specifically. While using alternative methods of surface preparation such as grooving, holes and nailing, indices of strength and behavior of reinforced wall under alternative methods of surface preparation have been studied. To achieve this aims, the number of 11 unreinforced masonry walls was constructed in the laboratory. These results show ductility index for reinforcement wall incrased 110 relative to unreinforced wall.
