Evaluation of residual welding stresses and fatigue crack behavior in tubular K-joints in compression

• Published in: Stahlbau, vol. 80, num. 7, p. 483-491
• Publication date: 2011

Tubular bridge design has to deal with fatigue issues. The fatigue susceptibility of these bridges, composed of circular hollow section profiles welded together in K-joints, is mainly due to stress concentrations, to welding imperfections and to tensile residual stresses induced by the welding process.
