Experimental Study on Evaluation of Replacing Minimum Web Reinforcement with Discrete Fibers in RC Deep Beams

This study investigates the possibility of replacing minimum web reinforcement in deep beams with discrete fibers. Additionally, equivalent dosage fibers required to obtain similar performance beam is investigated. Deep made plain concrete no fibers, as per AASHTO LFRD recommendations (0.3% both horizontal and vertical), a 0.5% volume fraction steel, macro-synthetic hybrid are tested at shear span height ratio (a/h) one. Test results show that presence 0.3% vertical directions increased peak load by 25% compared beams. However, it did not significantly change first diagonal crack load. With addition 49%, 42%, 63%, respectively, specimen. The steel improved cracking In contrast, affect but ductility higher deflections peak. Hybridization macro synthetic showed individual same ductility. or can be used completely replace directions).
