Title:
Abstract:	Das Tragverhalten statisch unbestimmter Stahlverbundträger - folgend kurz Verbundträger - wird im Gebrauchszustand maßgeblich durch die Rissbildung in den Bereichen negativer Momentenbeanspruchung beeinflusst. Verbundträger mit Teilfertigteilen weisen aufgrund lokaler Umlagerungen einige Besonderheiten auf, die mit den herkömmlichen Berechnungsverfahren nicht ausreichend beschrieben werden können. Dieser Beitrag stellt Berechnungsansätze vor, mit denen das spezifische Tragverhalten erfasst und Rissbildung, Rissbreiten sowie Verformungen wirklichkeitsnah beschrieben werden können. Crack and deformation behaviour of composite beams using partial-depth precast concrete units The structural behaviour of statically indeterminate composite beams under service conditions is basically influenced by crack formation in ranges with negative moments. Composite beams with partial-depth precast concrete units show some particularities, which cannot be described accurately using the established methods of calculation. This article presents methods of calculation, which can be used to cover the specific structural behavior and describe crack formation, crack widths and deformations realistically.
