WebApr 28, 2024 · Procedure for Design. The procedure for carrying out punching design can be divided into four basic steps. This steps are explained below. Step 1: Punching Shear Verification at the Column Face. The first step towards designing for punching shear is to verify its effect at the column face. At the column face, the punching shear stress must be … WebMar 26, 2024 · This is called "Punching shear", and requires concrete reinforcement at an angle: Assuming that the shear force F acts vertically, and that the cross section area of the beam is A, the stress at 45 degrees is: σ = F ∗ c o s ( 45) A c o s ( 45) σ = F A ∗ c o s 2 ( 45) < F A. So the shear stress vertically should always be higher than at 45 ...
