Maximum Shear Strength Limit for Reinforced Concrete Deep Beams
International Journal of Concrete Structures and MaterialsAlthough it is widely known that the shear strength of reinforced concrete (RC) deep beams is higher than that of general RC beams to which Bernoulli’s assumption can be applied, the maximum shear strength limit of deep beams is identical to that of ...

Sustainability of Using Steel Fibers in Reinforced Concrete Deep Beams without Stirrups
Sustainability, 2023 Reinforced Concrete (RC) deep beams perform better structurally when steel fibers are added, as this reduces the need for web steel reinforcements, boosts shear strength, and helps to bridge cracks. The current ACI 318-19 code does not include predicting

NEW MODEL OF ECO-FRIENDLY HYBRID DEEP BEAMS WITH WASTES OF CRUSHED CONCRETE
Jurnal Teknologi, 2023 This paper presents a new model of hybrid sustainable deep beams that include crushed coarse aggregates (RCA) in place of natural aggregates. RCA was in three replacement ratios: 0%, 50%, and 100%.
