Title:
Abstract:	Die Querkrafttragfähigkeit von Spannbeton-Fertigdecken wird bei einer Lagerung auf schlanken Trägern oder Unterzügen anstelle von starren Auflagern wie beispielsweise Wandscheiben deutlich herabgesetzt. Bisher existiert kein einheitliches Bemessungskonzept, das die verbleibende Tragfähigkeit zutreffend ermittelt. Dieser Beitrag beschreibt die Entwicklung eines Bemessungsmodells zur Bestimmung der Querkrafttragfähigkeit von Spannbeton-Fertigdecken bei biegeweicher Lagerung. Shear resistance of prestressed hollow core slabs on flexible supports - Part 1: Model derivation 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. So far, there is no standardised design concept to determine the residual bearing capacity appropriately. This paper describes the derivation of a design model to determine the shear resistance of precast prestressed hollow core slabs on flexible supports.
