The stability check depends not only on the section but on the whole beam behaviour: buckling and lateral-torsional buckling.
The following ULS checks are available for 2D members:
UC_Overall
The overall unity check is the maximum of all the individual unity checks.
UC_Single
The maximum unity check across all applied single checks.
UC_Combined
The maximum unity check across all applied combined checks.
UC_Stability
