| Abstract: | Steel fiber reinforced self-stressing concrete(SFRSC)was used as strengthening material,and fatigue properties of damaged simple-support beams strengthened to continuous beams were studied.SFRSC,steel fiber concrete and ordinary concrete were used as wet joints and composite layer materials to strengthen simple-support beams respectively.Through fatigue tests,stress levels of reinforcements in hogging moment area and mid-span,crack widths and mid-span deflection were comparatively analyzed.The experimental ... |
