Abstract:
The objective of this study was to examine the in-plane lateral load behavior of two full-scale fly ash brick masonry walls one unreinforced and the other confined before and after retrofitting. The quasi-static load test findings are shown here. The construction of the walls closely followed the masonry methods prevalent in Pakistan and throughout South Asia. Prior to retrofitting, the walls were tested to their peak resistance. The damaged walls were then retrofitted using grout injection followed by a ferrocement overlay and retested until they ultimately failed under identical condition. The damage pattern, energy dissipation, and force-deformation behavior of the walls evaluated both before and after retrofitting were used to evaluate the efficacy of the suggested confinement and retrofitting plan. Prior to retrofitting, test findings indicate that restricted masonry walls have nearly double the capacity of unreinforced masonry walls. The test findings following the retrofit show that the applied retrofitting strategy greatly increased the unreinforced masonry wall's lateral load capacity, while it had only a little positive impact on the confined masonry walls.
