Abstract
The influence of corrosion of steel bars (longitudinal bars and stirrups) on the shear behaviour of RC beams has been examined by experience. Experimental results indicate that, if corrosion level represented by maximum sectional-area loss is less than 35%, the corrosion of stirrups has little effect on the shear load carrying mechanism of RC beams and the shear capacity can be predicted accurately using modified truss theory. On the other hand, when the longitudinal bars corrode, the diagonal shear cracks shift to the loading point and cause a transition of load-carrying mechanism.
