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


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 Figure 01).

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

You can find more information on "Punching Load on Wall Ends and Wall Corners" and "Load Increasing Factor β" in the technical articles of our knowledge under Links below.
