A punching shear design check is to be carried out for the contact points of the front four columns with the foundation and ceiling slab. To do this, you have to select eight relevant nodes and double-click to open the editing dialog box. You can activate the "Punching Shear Design" option there.
In order to perform the punching shear design, it is also necessary to insert a basic reinforcement in the foundation slab. To do this, double-click the "Edit Surface"' dialog box and select the basic reinforcement that has already been defined in the "Surface Reinforcement" tab.
