IMPACT OF THE SIZE EFFECT ON SHEAR RESISTANCE OF BEAMS WITHOUT TRANSVERSE REINFORCEMENT

Abstract

This paper consider in depth the size effect and its influence on the shear resistance of beam elements without transverse reinforcement, as well as the approaches to take into account the size effect, based on the provisions of the fracture mechanics. The results of comparison of shear resistance models against the background of experimental data and verification of the influence of the size effect are presented. Based on the verification of the resistance models, this paper presents recommendations on the account of the size effect and the impact on the target value of the reliability index of structural elements.
