This volume addresses the specific subject of fatigue, a subject not familiar to many engineers, but still relevant for proper and good design of numerous steel structures. It explains all issues related to the subject: Basis of fatigue design, reliability and various verification formats, determination of stresses and stress ranges, fatigue strength, application range and limitations. It contains detailed examples of applications of the concepts, computation methods and verifications.

Das Buch befasst sich mit dem Thema Ermüdung - ein Thema, das vielen Ingenieuren nicht geläufig ist, das aber eine hohe Relevanz beim Entwurf von Stahlkonstruktionen besitzt. Folgende Fragen werden besprochen: Grundlagen der Ermüdungsberechnung, Dauerhaftigkeit und diverse Nachweismethoden, Spannungsermittlung, Ermüdungsfestigkeit, Anwendungsbereich und -grenzen. Anhand von detaillierten Beispielen werden Berechnungs- und Nachweisverfahren vertiefend erläutert.
