Abstract:A study of the infhxnce of variations of shear span and percentage of longi-tudinal steel on mode of failure, cracking strength, and ultimate strength ol reinforced concrete T-beams without web reinforcement is reported. Emphasis was placed on beams with large shear spans. The 25 beams tested included only simple-span beams under two symmetrical concentrated loads. The influence of mesh reinforcement in the flange, and that of longitudinal compres-sion reinforcement was also investigated. For a shear span ratio (a/d) between 4.0 and 8.0, the ratios ultimate shearing stress to cylinder strength, and cracking shearing stress to cylinder strength, were for all practical purposes constant. For the same a/d range, a large increase in the steel area did not affect rithcr the ultimate shear-ing strength or the cracking strength.
