Hi, how to fixed those problems in Sofistik Revit 2020
As the error message says, the punching shear check is not satisfied. The shear force V_Ed exceeds the maximum design shear stress at the column face V_Rd. So now you have to decide which solution you want to take. You can increase the dimensions of the column, you can increase the height of the slab, you can use special punching reinforcement, …
It is therefore up to you to choose which measures suit you.
