Because of the simplicity of laboratory tests when compared with real service conditions and many simplifying design assumptions, the resulting design provisions have been very general and often overly conservative. The recent developments in structural safety and reliability have provided bases upon which random loadings and reliability criteria can be used to develop simple but more realistic fatigue design criteria. To provide an indication of the applicability of some of these new hypotheses, laboratory tests conducted on butt-welded joints in structural steel and tested under a tension-biased random loading have been compared with a proposed random loading fatigue design criteria. Although of limited scope, the excellent correlation of the data indicates that more realistic design procedures for random loadings now are possible and can be used readily for the fatigue design of welded structures.
