Title:	Begrenzung der Biegeschlankheit nach Eurocode 2
Abstract:	Durchbiegungen in Stahlbetontragwerken müssen bereits im Rahmen des Entwurfes ausreichend begrenzt werden. Der Eurocode 2, der im Jahr 2012 bauaufsichtlich eingeführt wird, gibt hierzu neue Regeln vor, die im Ergebnis deutlich schärfer sind als diejenigen der DIN 1045 (Ausgabe 1988 und aktuelle Ausgabe 2008). Die Regeln des EC2 sind ihrer Natur nach jedoch keine Entwurfsgleichungen, mit denen die Bauteildicken direkt bestimmt werden können, sondern eher zur abschließenden Kontrolle des Entwurfes geeignet. Auf der Grundlage der Nachweisgleichungen des EC2 wurden daher Diagramme als direkte Bemessungshilfe entwickelt, die ein iteratives Vorgehen weitestgehend vermeiden und Architekten und Ingenieuren die Entwurfsarbeit deutlich erleichtern sollen. Limitation of span to depth ratio (slenderness) according to Eurocode 2 Deflections in reinforced concrete frames must already be sufficiently limited during design. The Eurocode 2, which will be implemented in 2012 in Germany, provides new rules, which are clearly more demanding than those of the DIN 1045 (issue 1988 and current issue 2008).The rules in EC2 are however, by their nature, not design equations from which the member dimensions can be directly determined. Therefore they are normally used for final verification of the design. To overcome this, design graphs, based on the design equations of EC2, have been prepared. These are meant to significantly help architects and engineers in the early stages of design by avoiding an iterative procedure as far as possible.
