Title:
Abstract:	Verbundträger mit Ganzfertigteilen weisen aufgrund der Bildung von Sammelrissen einige Besonderheiten im Vergleich zu Verbundträgern mit Ortbetonplatte und auch solchen mit Teilfertigteilen auf, die mit den herkömmlichen Berechnungsverfahren nicht ausreichend beschrieben werden können. Dieser Beitrag stellt Berechnungsansätze vor, mit denen die Sammelrisse und das spezifische Tragverhalten erfasst und Rissbildung, Rissbreiten sowie Verformungen wirklichkeitsnah beschrieben werden können. Calculation of crack widths for composite beams using full-depth precast concrete units Due to formation of accumulated cracks composite beams with full-depth precast concrete units compared to those with in-situ concrete and also 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 accumulated cracks and the specific structural behavior and describes crack formation, crack widths and deformations realistically.
