Lateral buckling verification is performed while member code check.
You decide if lateral buckling verification will be done while Code check member type definition.
For steel elements in can be checked by

for timber members

I did not fully understood your question
Lateral buckling verification is not performed for
angles
tube like sections
user defined sections with arbitrary shape
non typical parametric sections (cross)
Compound sections
For all codes it is performed for I, C and T sections.
There are exceptions for some codes. For instance parametric cross is verified according to Pn (polish code) and is not verified according to EN code.

HI again
I'm still a bit puzzled by this question. In the beam below, why has the system not performed any member stability checks even when all types of buckling were allowed in the member definition?
Also, what would the difference between checking or not checking the sway option be? When should this be done? Is it just related to the critical load calculated from your buckling analysis?
Thanks in advance
Antonio
Ad1 no stability check
No lateral buckling check because it is tube section
No buckling check, probably because element is subjected to tension
Ad2
Sway,non-sway option matters for automatic and semi automatic buckling length estimation procedures.
Please refer to the following thread sway,non-sway
