Summary: | This experimental program was designed for investigating the seismic performance and reinforcement effect of pre-damaged RC frame T-beams reinforced with sprayed basalt fiber reinforced polymer (BFRP). Four RC frame T-shape beams specimens, among which one was unstrengthened , one was undamaged and strengthened , and the other two were pre-damaged and strengthened, were tested under an incremental loading procedure of the pseudo-static, cyclic shear loads. The test results including the failure mode, ultimate bearing capacity, load-displacement hysteresis curves and ductility of specimens were obtained and analyzed. It indicates that spraying BFRP reinforcement can effectively increase the peak load and energy dissipation performance of damaged RC frame T-beams, ultimate lateral deformation and ductility of damaged RC frame T-beams can be improved obviously. Increasing the reinforcement thickness of sprayed BFRP can effectively improve the seismic reinforcement effect of T-shaped beams damaged by the earthquake. |
