Title:
Abstract:	Am Beispiel der gemauerten neunfeldrigen Eisenbahn-Bogenbrücke in Chemnitz werden für den Nachweis der Standsicherheit verschiedene Verfahren gegenübergestellt. Die maßgebende Stützlinie wird mithilfe einer speziellen FE-Berechnungssoftware ermittelt, welche die Strukturnichtlinearität von gemauerten Konstruktionen berücksichtigt. Die Bemessungsfestigkeit des Mauerwerks unter ausmittiger Beanspruchung wird mit verschiedenen Verfahren ermittelt. Zur Kalibrierung des Berechnungsmodells wurden Belastungsversuche mit einem 600-t-Schwertransport durchgeführt. Der Erhalt des Chemnitztal-Viadukts soll Ziel der Untersuchung sein. Analysing the masonry Chemnitztal-Viaduct with the aim of preservation of the railway bridge Using the example of a nine-field railway arch bridge in Chemnitz different methods for the verification of the structural stability are compared. The determination of the relevant thrust line is determined using a special FE calculation software, which takes into account the structural non-linearity of masonry constructions. The design resistance of the masonry under eccentric stresses is determined by various methods. For the calibration of the calculation model load tests were carried out with a 600 t heavy load. The preservation of the Chemnitztal Viaduct should be the aim of the analysis.
