Fiber-reinforced polymer (FRP) systems can be used for strengthening masonry structures and masonry elements among other options such as external steel plates, section enlargement with reinforced concrete (RC) overlays or shotcrete, steel bracing, and internal steel reinforcement. FRP systems offer advantages over traditional strengthening techniques: they are lightweight, relatively easy to install, and are corrosion-resistant. Due to the characteristics of FRP materials as well as the behavior of masonry members strengthened with FRP, specific guidance on the use of these systems is needed. This document offers a description of the unique material properties of FRP and committee recommendations on the engineering, construction, and inspection of FRP systems used to strengthen masonry. These guidelines are based on the knowledge gained from experimental research, analytical work, and field applications of FRP systems used to strengthen masonry structures. Keywords: buildings; columns; confinement; cracking; cyclic loading; detailing; earthquake resistance; fiber-reinforced polymers (FRPs); fibers; flexure; masonry; shear; strengthening; structural analysis; structural design; unreinforced; walls; wind resistance.<\/p>\n
