When should the punching load be determined with the (un)smoothed distribution of the shear forces at the critical perimeter?

Answer

There is no general recommendation for this.


For wall corners and wall ends, you can initially keep the default setting "Unsmoothed shear force over the critical perimeter."


After the calculation, you can graphically check the distribution of the shear force in the control perimeter.


Optionally, you can switch to "smoothed" (for example, when singularities occur).

Please note, however, that any singularities that may occur are also included in the beta calculation. It may also be necessary that the load increasing factor ß will be specified directly by the user.
