In this paper, recent results of the experimental investigation, which was aimed at disclosing some aspects of shear failure mechanism in concrete beams reinforced longitudinally, are presented. The aim of the test was to investigate the influence of a shear span-to-depth ratio and a beam size ...

(2010, 2012), however in most of the considered equations the degree of conservatism decreased with increasing beam depth. Moreover, comparing the size effect in this study with others from the literature indicated that the size effect is larger in beams reinforced with basalt FRP rebar than gla...
Reliability assessment of the behavior of reinforced and/or prestressed concrete beams sections in shear failure The object of this article is to be able to simulate the behavior of reinforced and/or prestressed concrete beam's section in the shear loading through a model allowing the evaluation of...
Failure curves, defining peak pressure versus rise time domains where direct shear failure is possible, are compared to experimental evidence for specific beam geometries and load rates. Post failure deterministic and stochastic models are introduced as candidates for analysis beyond incipient shear ...

This paper investigates mechanisms that result in snap-back failure in a reinforced concrete (RC) beam, i.e., beams failed by shear are investigated focusing on the location where the large strain localization is accumulated. Then the general tendency of shears failing beams in generating snap-ba...
Local shear failureConcrete cast-in-place T-beam highway bridges are often constructed by casting the girders and the deck separately, creating a cold joint between the girders and the deck. Under certain circumstances, cracking and visible slippage can occur in this joint, resulting in fracture ...
All three relations capture the dependence of shear strength on the size of the beam, the ratio of shear span to beam depth, longitudinal reinforcement ratio, maximum aggregate size, and concrete strength. The limits of these formulas agree well with the limit solutions of shear failure load ...
Shear failure is catastrophic and occurs usually without advance warning; thus it is desirable that the beam fails in flexure rather than in shear. Many existing reinforced concrete (RC) members are found to be deficient in shear strength and need to be repaired. Externally bonded reinforcement su...
