Abstract

Research on the use of fiber-reinforced polymer (FRP) composites for strengthening of unreinforced or inadequately reinforced hollow concrete masonry is covered in this paper. Quasi-static shear wall tests were conducted on unreinforced concrete masonry specimens that had been strengthened with unidirectional glass fiber strips applied to the surface of the masonry using a two-part epoxy to form a surface-bonded GFRP composite. The strips were strategically placed to improve both flexural and shear strength in the in-plane direction. The GFRP composite system was combined with conventional structural steel and reinforcing steel connections that were designed to yield before the composite ruptured, resulting in a ductile failure mode under cyclic testing. The drift capacities of the tested specimens ranged from 0.6% to 1.7%.
