    Dear Friend:
    i understand from u about built up section as to be the profiled section so If u r talking about the remained stress in the profile steel section (I BEAM) so it is so easy.
    all profiled sections r stressed themself without loading couse of coming cold after casting (pouring) to set out (thats mean shrinks).
    and if u r interested about this matter, u can look at the subject in any steel design book.
    but beware that this is not buckling, it is named as presteressed or remained strees and its deformations is very small and may not be seen by normal eye
    in addition in design they r not calculting this stresses couse it is small especially in small section. but in big section and if the design is for important major beam or danger node so u should take it in consideration (u can go backt to european code for this clouse)
    thx for u
