Results of an theoretical investigation of the shear strength of reinforced concrete tee beams made from high strength concrete are summarized in this paper. In addition to the effect of both flange to web width ratio of tee beams and compressive strength of the concrete, the effect of other variables such as shear span to depth ratio, percentage of both tension steel and web reinforcement were taken into consideration in predicting shear strength of high strength reinforced concrete tee beams. Finite element method was used to analyze twenty six beams subjected to two point static loading. Proposed equation to estimate the shear strength of the analyzed beams was developed. The predicated shear strengths by the proposed equation were compared with Zustty, ACI code, Egyptian code.
