Title:	Bewehrungs- und Konstruktionsregeln des Stahlbetonbaus im Wandel der Zeit
Abstract:	Bauen im Bestand stellt für alle Beteiligten eine große Herausforderung dar, da wesentliche Merkmale eines Bestandstragwerkes in der Regel unbekannt sind. Neben fehlenden Angaben bezüglich der Eigenschaften der verwendeten Materialien liegen oftmals nur wenige Informationen zur Art der konstruktiven Durchbildung der Bauteile vor. In diesem Beitrag werden Hinweise zur historischen Entwicklung wesentlicher Bewehrungs- und Konstruktionsregeln in Deutschland gegeben. Der Überblick soll helfen, bereits durch die Zuordnung von Bestandstragwerken zu einer bestimmten Normengeneration potenzielle Defizite hinsichtlich der Bewehrungsführung identifizieren zu können. Due to the reason that the main characteristics of an existing building are normally not known, the design and construction of these structures is a challenge for all participants. Besides the fact that the properties of the used materials are not known, there is only little information about the detailing of the structural members available. In this paper, reference is given to the historical development of the essential reinforcement and construction rules in Germany. This overview is aimed to help identifying potential shortcomings of the configuration of the reinforcement by relating an existing structure to a particular standard generation.
