In RSTAB, I would like to rigidly enter the bedding ratio for the translational, shear, and torsional spring. Which values do I have to define?


A completely rigid support is not possible. The maximum values of the translational, shear, and rotational springs are limited as follows:

translational spring
C1, x 1.0 x 10 8 kN/m²
C1, y 1.0 x 10 9 kN/m²
C1, e.g. 1.0 x 10 9 kN/m²

Shear spring
C2, x 1.0 x 10 8 kN
C2, y 1.0 x 10 8 kN
C2, e.g. 1.0 x 10 8 kN

rotational spring
Cφ 1.0 x 10 8 kNm/rad/m
