(PDF) Punching Shear Strength of Reinforced Concrete …

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. The inclination … WebJan 1, 2024 · It was found that the rebar corrosion can change the failure mode of the connection from flexural or shear-flexural failure to punching shear and reduce the punching shear strength significantly.
