Unreinforced masonry buildings have shown to be prone to seismic forces due to their brittle behavior. Therefore, many experimental and analytical studies have been conducted on different retrofitting methods including the use of Fiber Reinforced Polymers (FRP) to improve the lateral strength and ductility of these structures. Time history dynamic analyses were conducted on an uncracked and cracked one story unreinforced masonry structure with window and door openings. Based on the analytical results, the effect of cracks and openings on the seismic response of the structure was investigated. Thereafter, the building was retrofitted with FRP strips to improve the post cracking behavior. It was found that masonry cracking increases the damping of the masonry structure. However, the integrity of the structure must be maintained to prevent total collapse, thus satisfying the life safety requirements of the occupants.
