WebMar 28, 2024 · Such software may not calculate Beta factors though and care needs to be taken to get this right. The Beta factor in the EC2 punching shear rules accounts for the uneven distribution of punching shear stress around the control perimeter, and plays an important part in determining the required punching shear reinforcement. WebApr 10, 2024 · Chapter 6.4.1 (5) EC-2 – Punching calculation hypothesis . This may be interpreted in two ways: · Typical case of punching of a column – The load has to reach the column, normally through a slab, in a uniform way: Figure 2. Uniformly distributed loads on a slab transmitted to the column
WebNov 22, 2009 · Consider an existing, 4" thick, unreinforced slab on grade that must support a new concentrated load. I want to check punching shear with the equation Vc = 4* (sqrtf'c)*bo*d (base plate is square). My question is what do I use for d? The ACI code defines d in this case as the effective depth, but I'm assuming the slab is not reinforced.
