要旨 Spatially localized cracking along corroded reinforcement was experimentally studied to clarify its effect on shear capacity. It was found that the effect of local damage be adverse, insignificant or even favourable depending on locations. The damage locations were examined 1) around compression and tention fibers at a mid-span, 2) near supports inside ashear span, 3) around anchorage zone including beam support and 4) the whole shear span. Though the selective corrosion crack in between supports may zone elevate the shear capacity caused by an arch action, RC beams with cracking damage in the anchrage zone exhibited significantly reduced capacity accompanying sliding shear failure at the anchorage zone.
