Are there any recommendations or literature and standard references to the "Limit Values for Stability Analysis" settings in Details of RF‑/STEEL EC3?

Answer

The filter functions in the "Details" dialog box, "Stability" tab, should allow you to neglect small moments or compression forces, and thus, for example, to perform a buckling analysis for asymmetric cross-sections without taking into account the interaction "bending and compression." Otherwise, a warning would appear saying that no stability analysis is possible.

The limits are applied and set at the user's discretion and usually agreed with a tester. Dlubal Software cannot provide a general recommendation. However, it can be reasonable for very slender components to reduce the limit value to 0%.
