Análise de fadiga de ligações soldadas de barras de aço tubulares (original) (raw)

A fatigue analysis of the welded tubular joints in a metallic trussed bride is presented herein. The fatigue life of these joints was achieved be means of geometric and nominal stress methods established by the CIDECT 8 (2000) and Eurocode 3 (2005) standards, with an approach based on tension cycles (curves S-N). In addition, a comparative discussion of these two methods is presented; their advantages, limitations, etc. The results demonstrate which method is best applicable for the given situation of the project.
