It is also better to enter the supports as non-linear supports. In the vertical direction these supports can only<br />
take pressure and no tension. This is entered in the z direction with “rigid press only”. The rotations are taken<br />
free in all directions.<br />
For the degrees of freedom according to the x and y displacements, the code prEN12812:2003, Annex B is<br />
applied. In this, the friction coefficients between various materials are entered. If we suppose that the<br />
scaffolding is placed on wood, we can see in this code that the maximal and minimal frictions coefficient<br />
between wood and steel is 1.2 and 0.5. On average a value of 0.85 is adopted. This value is also entered in<br />
<strong>Scia</strong> Engineer.<br />
For “C flex” a large value is taken. This corresponds to a large rigidity of the support in the x- and the y-<br />
direction before the friction is exceeded.
