Numerical investigation of shear behavior of prestressed concrete beams without stirrups

Beschreibung

Despite comprehensive research over the past decades, the mechanisms of shear failure of RC Beams are not fully understood. Latest research output on this topic indicates major influence of the structural system and the type of loading. Based on these results, this paper deals with the influence of normal compressive stress on the shear capacity of simply supported beams and cantilever beams without stirrups. A numerical model, based on experimental investigations, is established.

A comprehensive parametric study is carried out to determine the influences of parameters such as concrete compressive stress (σcp), shear slenderness (a/d-ratio) and longitudinal reinforcement ratio (ρl) in combination with different static systems. The results show a significant influence of the compressive stress on the shear capacity. This, however, varies depending on the static system, the longitudinal reinforcement ratio, and the shear slenderness of the beams.
