Abstract

Recently, the deterioration of concrete structures have been increased by the damage from salt, carbonization, freezing & thawing and the others. Reinforcement corrosion is the principal cause of deterioration of reinforced concrete. Unfortunately, full bond is assumed in all existing shear models, a condition which is often not fulfilled when assessing damaged structures. It is therefore very important to increase the understanding of how reduced bond influences the load carying capacity particularly for shear. Therefore in this study an equation is proposed to evaluate the residual shear strength considered deterioration.
