Abstract—Accurate prediction of the shear behavior of Reinforced Concrete (RC) beams unlike to its flexural behavior which can generally be well predicted is a challenging problem due to the complexity of the shear transfer mechanism. This issue can be more critical for High-Strength Concrete (HSC) beams compared with the beams with normal strength concrete. The present study adopts an efficient rule based data mining approach: M5' algorithm to potential development of a new formulation for predicting the shear strength of HSC slender RC beams without stirrup. A comprehensive database containing several effective parameters that consider geometrical and mechanical properties of concrete, aggregate and reinforcement are involved in prediction of the shear strength. Comparison between developed model and the most common design codes demonstrates the superiority of the developed model in term of accuracy. Furthermore, the safety analysis based on Demerit Points Classification scale also confirms the reliability of the proposed formulation.
