Abstract: Based on he ul ima e load cri erion, he calcula ion me hods of he whole s abili y of axially loaded com
pression member of coldformed hinwalled s eel sec ions considering bo h coldformed residual s ress and ini ial ou
ofs raigh ness are researched. By calcula ing of crimping angle s eel, he resul s are gained. The calcula ing resul s
are compared wi h bo h he resul s of experience and he calcula ing resul s of he Technical code of coldformed thin
wall steel structures GB 500182002, i is proved ha he me hod is feasible.
