This paper is concerned with the design of complex welded structures subjected to fatigue loadings. In the last years it has been developed a new approach for predicting the high cycle fatigue behaviour of welded joints, based on the Notch-Stress Intensity Factors of the uncracked geometries, which

Abstract
Many steel structures and components are fabricated from steel plates and steel castings. The dominating joining method is welding for all kinds of transport vehicles and this paper describes briefly main problems in connection with design and fabrication of fatigue loaded structures. Design and fabrication has developed during the last 30 years and today we have tools, methods and knowledge to produce more optimised structures. Some of the work has been performed as joint work within Nordic projects and within IIW (International Institute of Welding). FEβmodelling, improved design rules, knowledge about influence from defects and residual stresses, new manufacturing methods and scientific based weld quality rules are briefly discussed in this paper.

In this paper a design procedure for fatigue assessment of welded pipe penetrations in plated structures is presented. The background for the procedure is given. It applies to full penetrations welds, partial penetrations welds and fillet welds. Fatigue cracking from the weld toe and from the root o
