Download E-books Stäbe mit undeformierbaren Querschnitten (German Edition) PDF

Nach fünfzehnjähriger praktischer und theoretischer Zusammenarbeit der beiden Autoren wird hier ein Buch herausgegeben, das sowohl für den Bau­ ingenieur in der Praxis wie auch für den Studenten geschrieben wurde. Es be­ handelt die Berechnung und Ausführung dünnwandiger Stäbe, wobei der Baustoff dieser Stäbe aus Stahl, Leichtmetall, Stahlbeton oder vorgespanntem Stahlbeton bestehen kann. Mit der zunehmenden Beliebtheit leichter Konstruktionen, vorwiegend im Hochbau, stellte sich die Forderung nach einer möglichst genauen Erfassung neu­ zeitlicher Berechnungsmethoden für solche Leichtkonstruktionen. Es drängte sich daher der Gedanke auf, das bisher Erreichte festzuhalten, zu ergänzen und zu er­ weitern, um dem Konstrukteur die Unterlagen in einer ihm verständlichen shape zu übermitteln. Dieses Buch legt infolgedessen nicht in erster Linie Wert auf die Darstellung komplizierter Theorien, sondem möchte dem in der Praxis stehenden Ingenieur als Grundlage und Rüstzeug für die Lösung seiner Aufgaben dienen. Dabei soll jedoch festgehalten werden, daß, um den Geltungsbereich und die Grenzen der angegebenen Formeln zu erkennen, die hier gegebenen theoretischen Kenntnisse unerläßlich sind.
