Title:
Abstract:	Bei Spannbetonkonstruktionen ist grundsätzlich ein Nachweis der Verformungen erforderlich. Ausgehend von allgemeinen Betrachtungen zum Nachweis der Bauteilverformungen werden wesentliche materialseitige Einflüsse auf die Verformungsvorhersage diskutiert. Es wird deutlich, dass eine genaue Berechnung der Verformung nur bedingt möglich ist. Am Beispiel der Vorpommernbrücke über die Warnow in Rostock wird der Einfluss von nichtlinearen Materialgesetzen auf die Verformungsvorhersage verdeutlicht. Der Vergleich der Berechnungsergebnisse mit den Messwerten der Verformungen ergab eine gute Übereinstimmung. Comparison of Calculated and Measured Deformations of the West-Pomerania-Bridge in Rostock Generally, a proof of the deformations of prestressed concreteconstructions is required. On the basis of a general consideration of the structural deformations the influence of significant material characteristics on the predicted deformations is discussed in this paper. It will be obvious, that an accurate estimation is only possible in a restricted manner. The West-Pomerania-Bridge over the Warnow in Rostock serves as an example, to show the influence of non-linear material-laws on the predicted deformations. The comparison of the calculated deformations with the measurements results in a good agreement.
