Experimental investigation on the shear capacity of RC beams with curtailed reinforcement

摘要

In continuous beams with both positive and negative moments, curtailed reinforcement is often used to increase the bending capacity locally. In practice, it is normally considered as a safe assumption to neglect the curtailed reinforcement when calculating the shear capacity. However, some tests from the literature have indicated that the end of curtailed reinforcement may decrease the shear capacity. Not all shear models take this effect into account. These models tend to overestimate the shear capacity significantly.
