Evaluación del ajuste e introducción de la seguridad en el modelo experimental del EC-2 para estimar la capacidad a cortante en elementos lineales de hormigón armado sin armadura transversal

Evaluation of adjustment and introduction of safety in the EC-2 experimental model for the estimation of the shear strength of linear reinforced concrete specimens without transverse reinforcement

It can be demonstrated that the mechanism of resistance regarding shear is very complex because of the great number of factors involved in the evaluation of this resistance. Within the framework of a more extensive investigation, an evaluation of the equations of the Spanish, European and American codes has been made in light of existing tests with reinforced concrete beams without transverse reinforcement on shear failure. Even though the validity of these simple verification models can be gathered from results of the analysis, conclusions about the convenience of modifying the current formulations to improve the coherence and the adjustments between theory and investigation have been established.
