Strengthening Thechnics for Masonry Walls Using ExternalyBonded FRP Composits

Unreinforced Masonry (URM) buildings constitute an important part of the civil engineering structures, and are vulnerable to lateral loading. URM walls have a low resistance against lateral loading due to their low flexural capacity and their brittle mode of failure . Fiber reinforced polymer (FRP) composite materials are developed options for strengthening of masonry buildings. The application of FRP composites as externally bonded reinforcement in repairing and strengthening the masonry walls has becoming more attractive than the traditional methods which are based on steel elements.In this research, an analytical study has been conducted to show the out-of-plane behavior of FRP strengthened masonry walls. The wall panels made of clay bricks have been investigated and the effectiveness of different types of FRP elements used for strengthening is analyzed.
