ABSTRACT:
Reinforcing system for retrofitting wall to increase the ductility and resistance to shear forces of a gypsum board wall to a level comparable to plywood-sheathed wall. Fiber-reinforced polymer panel is attached to substantially cover surface of gypsum board to protect it against rupture in earthquake. Reinforcement is enhanced by fiber anchors installed along base of wall and door frames. Optional connector strips tie together door and window frames to prevent separation from wall.
