Question

Why is the beta factor of the punching shear design of a wall corner given as 1.0?


Answer:

The reason for the load increasing factor β = 1.0 is the fact that the "Unsmoothed shear force" is applied in Window 1.5. This is the default setting for wall corners and wall ends (see Image 01).

If you change the setting to "Smoothed shear force over the critical perimeter", the load increasing factor β applies (see Image 02). By default, this is determined using the fully plastic shear stress distribution according to EN 1992‑1‑1, 6.4.3 (3).
