WebMar 29, 2024 · JAE (Structural) 29 Mar 19 15:03. Not familiar with British standards but for ACI 318 (in the US) there is a chapter on Plain Concrete (i.e. unreinforced) where they offer several formulae for shear. For beam action the suggest ΦVn = Φ x 4/3 x λ x sqrt (f'c) x b x h. where. λ is a factor = 1.0 for normal weight 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 …
