Design of Cold-formed Steel Structures

Das Buch behandelt den Entwurf von Stahlkonstruktionen aus kaltgeformten dünnwandigen Bauteilen und Blechen nach DIN EN 1993-1-3 (EC3, Teil 1-3). Zunächst werden die theoretischen Grundlagen und Entwurfsregeln dargestellt. Diese werden in den jeweiligen Kapiteln anhand von ausführlichen Beispielen (auf mehr als 200 Seiten) vertiefend erläutert.

Zusammenfassung
The book is concerned with design of cold-formed steel structures in building based on the Eurocode 3 package, particularly on EN 1993-1-3.
It contains the essentials of theoretical background and design rules for cold-formed steel sections and sheeting, members and connections for building applications.
Elaborated examples and design applications - more than 200 pages - are included in the respective chapters in order to provide a better understanding to the reader.
