Title:	Querkraftbemessung von Spannbeton-Fertigdecken bei biegeweicher Lagerung
Abstract:	Die Querkrafttragfähigkeit von Spannbeton-Fertigdecken wird bei einer Lagerung auf schlanken Trägern oder Unterzügen anstelle von starren Auflagern wie beispielsweise Wandscheiben deutlich herabgesetzt. In Teil 1 dieses Beitrags wurde ein Bemessungsmodell für Querkraft bei biegeweicher Lagerung hergeleitet. Der vorliegende zweite Teil beschreibt die Kalibrierung und Validierung der Modellparameter anhand der Ergebnisse von 21 Großversuchen an biegeweich gelagerten Deckensystemen aus Finnland und Deutschland. Shear design of prestressed hollow core slabs on flexible supports - Part 2: Model calibration and validation The shear resistance of hollow core slabs is considerably reduced when the slabs are bedded on flexible supports like slender beams or girders instead of rigid walls. In the first part of this paper a design model to determine the shear resistance on flexible supports has been derived. This second part describes the calibration and validation of the model parameters based on the results of 21 full-scale tests on floor systems with flexible supports from Finland and Germany.
