SHEAR BEHAVIOR OF REINFORCEMENT CONCRETE BEAMS WITH CORRODED STIRRUPS

摘要

There have been few reports on the shear behavior of reinforced concrete (RC) beams with corroded stirrups, and the influence of stirrup corrosion has yet to be identified. Given this background, experimental investigations were carried out to investigate the shear behavior of RC beams containing corroded stirrups. Our Investigation results reveal that if the percentage local maximum mass loss is below 35% , there is little influence on the load-carrying mechanism. The concrete shear resistance seems to change little and the shear capacity can be calculated by just taking into consideration the reduction in stirrup shear resistance. It is also found that the anchorage conditions of the stirrups have a predominant influence on the shears of RC beams.
