| Abstract: | By testing the aseismic experiments of three masonry wall specimens under horizontal cyclic loading with constant gravity loads,the aseismic behaviors of the unreinforced masonry walls with door openings strengthened with carbon fibre reinforced polymer(CFRP) sheets and sprayed chopped glass fibre reinforced polymer(GFRP) were investigated.The aseismic strengthening effects were compared in aspect of the failure modes,shear capacity,hysteresis response,deterioration of rigidity,and ability of energy dissipa... |
