Abstract:A new approach for seismic retrofitting of unreinforced masonry structures is presented. Results from flexural tests of six masonry beams are reported. The beams were strengthened by epoxying a composite fabric to their tension face. The variables studied include the type of epoxy, fabric, mortar, brick, and the finished surface of the wall. It is shown that both the strength and ductility of the beams were significantly improved. When a sufficient amount of fabric is used to prevent premature tension failure, the integrity of the beam is maintained until the beam fails by reaching the compressive strength of the masonry.
