I have entered a 2D frame and would like to provide the ridge with a lateral and torsional restraint. Do I have to enter an intermediate support or a nodal support in RF-/STEEL EC3?

Answer

You can either define the nodal support or the intermediate restraint in RF-/STEEL EC3.


If you already have nodes in your actual RFEM or RSTAB model, we recommend directly entering the nodal support in the 1.7 dialog box, because you can select the nodes directly in the model. See Figure 01.

If you want to consider intermediate storage at a point in a horizontal beam where you do not have a node available in your actual system, you can use the intermediate support and specify the position of the intermediate support (for example, lateral and torsional restraint) there. See Figure 02.
