Question: How to set up the SLS check for steel?
Answer: To perform the SLS check for steel, you need to specify the following data:
Spans, deflection limits, and deflection values can be entered via buckling settings, which you can access through the Properties window in each element.

To adjust the spans of the elements:
Spans of 1D elements (beams, columns) can be adjusted (independently for local z and y directions) via buckling settings.

Deflection limits can be set in the "buckling settings". Deflection limits can be adjusted independently for local y and z directions and independently of total and variable loads.
To set up deflection limits for elements:
