Shear Behaviour in Slender Reinforced Concrete Beams with and without Transverse Reinforcement
… investigates the influence of flexural reinforcement ratios on CSC shape variability. The findings show how varying reinforcement ratios between 0.84% and 2.35% impact the overall behaviour of the CSC and subsequently affect shear capacity. A novel crack kinematic model is proposed based …
