The shear capacity of a reinforced-concrete member provided with web reinforcement is evaluated in this paper by introducing a model that is a generalization of Nielsen’s model (1999) based on the variable-inclination stressfield approach. The proposed model predicts the shear capacity of R/C beams reinforced by means of two differently-inclined transverse systems and containing also longitudinal web reinforcement. This is also the case of Hybrid Steel-Trussed Concrete Beams, that are increasingly used by structural designers. A set of numerical analyses demonstrates the efficiency of the proposed double transverse-reinforcement system in enhancing the shear capacity of R/C beams.

Abstract
The shear capacity of a reinforced-concrete member provided with web reinforcement is evaluated in this paper by introducing a model that is a generalization of Nielsen’s model (1999) based on the variable-inclination stressfield approach. The proposed model predicts the shear capacity of R/C beams reinforced by means of two differently-inclined transverse systems and containing also longitudinal web reinforcement. This is also the case of Hybrid Steel-Trussed Concrete Beams, that are increasingly used by structural designers. A set of numerical analyses demonstrates the efficiency of the proposed double transverse-reinforcement system in enhancing the shear capacity of R/C beams.Pubblicazioni consigliate
