When designing a beam I would like to neglect the torsion included in the stability analyzes using the filters described in Knowledge Base Article #001498.
After having defined a filter, a torsion warning appears in the same x-location again. Do the design internal forces change or what is the cause of it?

Answer

The design internal forces do not change because no load change has been defined. The torsional stresses are calculated once with Gamma M1 1.0 and once with Gamma M1 according to the National Annex, so that the warning can appear twice. If the filter is increased once more in the following, another x-location (or loading from LC/CO/RC) can also become governing for the warning.
