Design of Steel Structures

Dieses Buch bietet eine Einführung in die grundlegenden Verfahren des Eurocode 3 zur Konstruktion von Stahlbauten und Stahlbauteilen und erleichtert so die praktische Anwendung und Umsetzung. Insbesondere wird in dieser Uk-Edition auf die Regelungen der britischen Nationalen Anhänge eingegangen.
Nach einer Erläuterung der Grundlagen der Tragwerksplanung, u.a. Bemessungsverfahren von Grenzzuständen, werden Baustoffnormen und deren Anwendungsbereiche detailliert beschrieben. Statische Berechungsverfahren und -modelle werden ebenso behandelt wie Konstruktionskriterien und -verfahren für verschiedenste Tragwerksbauteile. Die weiteren Kapitel widmen sich ausführlich elastischen und plastischen Bemessungskonzepten und den zugehörigen Anwendungsbereichen, die beispielhaft anhand eines ausgesteiften Stahlrahmenbauwerks und eines Industriebaus Schritt für Schritt beschrieben werden.
Dieses Handbuch vermittelt nicht nur die erforderlichen theoretischen Grundlagen, sondern eignet sich auch als Nachschlagwerk für Ingenieure. Der hohe Praxisbezug wird in den vielen konkreten Beispielen deutlich. So werden Stahlbauten statisch berechnet und Bauteile, die unter den verschiedensten Bedingungen zum Einsatz kommen, geplant. Diese Beispiele helfen beim reibungslosen Übergang früherer nationaler Regeln hin zu den harmonisierten technischen Eurocode-Standards.

Résumé
This book introduces the design concept of Eurocode 3 for steel structures in building construction, and their practical application. It especially comments on the regulations of the british National Annexes. Following a discussion of the basis of design, including the limit state approach, the material standards and their use are detailed. The fundamentals of structural analysis and modeling are presented, followed by the design criteria and approaches for various types of structural members. The following chapters expand on the principles and applications of elastic and plastic design, each exemplified by the step-by-step design calculation of a braced steel-framed building and an industrial building, respectively.

Besides providing the necessary theoretical concepts for a good understanding, this manual intends to be a supporting tool for the use of practicing engineers. In order of this purpose, throughout the book, numerous worked examples are provided, concerning the analysis of steel structures and the design of elements under several types of actions. These examples will provide for a smooth transition from earlier national codes to the Eurocode.
