Moreover, the existing design formulas given by ACI 318–19, CSA 23.3–14, Eurocode 2, and BS 8110–97 were found to be unreliable for the prediction …

Punching Shear Strength in Concrete Slabs

WebThe Punching shear in reinforced concrete slabs can be considered as a 2D analog of the shear observed in beams. This kind of failure occurs as a sudden rupture. This rupture … WebA method to evaluate the punching shear strength of reinforced concrete (RC) flat slabs without shear reinforcement at the connection to interior columns is proposed. The method is based on the assumption that the punching shear strength is controlled by the inclination of a unique punching shear crack that produces a conical failure surface.
