Buckling resistance and residual stresses of welded HSS box columns
Steel Construction, Volume 19, Issue 1, Page 37-49, February 2026.Abstract Welded box columns made of high‐strength steels (HSS) are characterized by high buckling resistance and low self‐weight. The residual stresses introduced by the welding process are of particular importance. In the area of the weld seams, the cooling process creates residual tensile stresses that are in equilibrium with the compression stresses
