Title:
Abstract:	Im Eurocode 3 wird im Gegensatz zu DIN 18800 die Bemessung von Verbindungen nicht in der Grundnorm DIN EN 1993-1-1, sondern in anderen Normenteilen geregelt. Dieser Beitrag behandelt die Bemessung geschweißter Verbindungen nach DIN EN 1993-1-8, die auch Hohlprofile, aber weder dünnwandige Bauteile noch Stähle höherer Festigkeit als S460 einschließt, vergleicht diese Bemessung mit der nach DIN 18800-1, erläutert sie an Beispielen und hebt die wesentlichen Änderungen hervor. Da diese Änderungen auch die im Vergleich zu DIN 18800 viel stärkere Verknüpfung der in der Tragwerksplanung ansetzbaren Beanspruchbarkeiten mit dem Aufwand der Prüfung und Qualitätsüberwachung bei der Herstellung betreffen, werden abschließend wichtige Regelungen der DIN EN 1090-2 zur Ausführung und Prüfung von Schweißnähten beschrieben, die auch der Tragwerksplaner kennen muss. Welded connections according to DIN EN 1993-1-8. In contrast to DIN 18800 the design of welded connections in Eurocode 3 is not contained in the part for the general design rules but is given in special parts of this standard. This paper deals with the design rules of DIN EN 1993-1-8 for welded connections, which also include hollow sections, but exclude thin-walled members and steel grades beyond S460. These design rules of DIN EN 1993-1-8 are explained in examples and compared to the design according DIN 18800-1 with pointing out the essential differences. The interrelation between the resistance applicable for design calculation and the extent of inspection and testing with the execution of the structures is much stronger in DIN EN 1993-1-8 than in DIN 18800. Therefore finally the essential rules of DIN EN 1090-2 concerning inspection and testing of welds which are relevant for the weld design are described.
