Creating Lateral Intermediate Supports

Tips & Tricks

In RF-/STEEL EC3, the Window 1.4 Lateral Intermediate Supports offers you the option to define lateral intermediate supports at individual members. These supports are created from connected purlins and horizontal beams, for example, and increase the resistance against lateral-torsional buckling. Lateral intermediate supports can be entered either with a relative or an absolute distance.

The degrees of freedom φx and uy at the locations of the lateral intermediate supports are restrained in the calculation of the critical moment for lateral torsional buckling. In the example, the input of the lateral intermediate supports is demonstrated using a member as well as a set of members. In RF‑/STEEL EC3, both systems are handled equally, thus leading to the same results.
