Abstract:
Several Reinforced Concrete Beams were tested to determine the validity of the usual assumptions that longitudinal reinforcement does not transfer vertical shear across a diagonal tension crack and that the maximum compressive strain within the shear span is developed at the extreme fiber. Extensive strain measurements in the steel and the concrete indicated that a plane section did not remain plane following development of a diagonal crack and that the maximum compressive strains in the concrete occurred some distance below the extreme fiber. The longitudinal reinforcement was found to carry considerable vertical shear across a crack, but this force decreased rapidly as the load approached the maximum.
