【 摘 要 】

The second-order analysis is used to examine the laced built-up member with two extruded I-sections under combined compression and bending. The member bottom end is fixed, and the upper one is free in the case of in-plane buckling. The member is restrained against out-of-plane buckling at both ends. The global initial sway imperfection is taken into account instead of the local bow imperfection.
