Abstract
In this paper, recent results of the experimental investigation which was aimed at disclosing some aspects of shear failure in flexural concrete beams reinforced longitudinally, are presented. The performed tests have showed that the size of the member affects shear failure mechanism. In tested beams the static scheme, concrete grade and longitudinal reinforcement were the same whereas the effective length, leff, varied from 0.8 to 1.8 m. Taking into account the shear strength and the mode of failure obtained during the experiment, it was observed that tested beams should be divided on short beams and slender beams as the character of cracking process and failure differed significantly in beams of leff = 0.8 and 1.0 m, as compared with beams of leff > 1.0 m.
