Abstract: This research presents an experimental and theoretical studies on the structural behavior of high strength selfcompacted concrete I-beams. The main objective is to arrive the mode of failure of I beams which reinforced with and without web reinforcement. The experimental program presents the obtained results of tested eight high strength self compacting concrete I- beams specially reinforced to ensure a shear failure. All beams were tested simply supported along span 2400mm and subjected to four lines loadings until failure. The main variables were web thickness. The presence of web reinforcement in concrete beams increases its shear capacity and improves the ductility of the beam. Increasing the loading span to depth ratio decreased the failure load of concrete beams with web reinforcement, increasing the loading span to depth ratio decreased the failure load of concrete beams with web reinforcement, increasing (a/d) ratio from 2.4 to 2.9 led to a decrease in failure load by 33.3%. The effect of the studied variables are presented and discussed.
