Shear Behavior of Reinforced Concrete Beams with High-Strength Stirrups

摘要

The authors report on tests with 32 simply supported reinforced concrete (RC) beams with high-strength shear reinforcement to correct the maximum yield strength of shear reinforcement, as defined in ACI 318-08x and CSA A23.3-04.6 The aim of the limitation of the maximum amount of the shear reinforcement ratio in the specifications is to prevent the brittle failure after inclined cracking occurs and the crushing of web concrete before the shear reinforcement yields.
