Abstract: | Walzträger in Beton (WIB) stellen für einfeldrige Eisenbahnbrücken mit bis zu 25 m Spannweite eine attraktive Lösung dar. Das Verformungsverhalten derartiger Bauwerke wird durch die Rissbildung des Betons wesentlich beeinflusst, was daher rechnerisch realitätsnah erfasst werden muss. Im vorliegenden Beitrag wird ein Näherungsverfahren vorgeschlagen, welches für die Verformungsberechnung einbetonierter Stahlquerschnitte unter Gebrauchslasten geeignet ist. A proposal for the calculation of deformations in concrete - encased steel beams Concrete-encased steel beams are attractive solutions for railroad bridges with spans up to 25 meters. By this type of constructions the cracking of concrete is of great importance. In this article a calculation procedure is suggested, which is appropriate for evaluating deformations of steel-profiles integrated in concrete under service conditions. |
