Title:
Abstract:	Sandwichelemente aus außenliegenden dünnwandigen Stahldeckschichten mit innenliegendem Dämmkern stellen mittlerweile die Standardlösung für den Raumabschluss im Hallenbau dar. Für die Wandverkleidung werden üblicherweise Elemente mit beidseitig flachen Deckschichten verwendet. Bei Dachelementen ist mindestens eine Deckschicht profiliert. In der Praxis werden sowohl Wand- als auch Dachelemente als Mehrfeldträger verlegt, um die Bauausführung zu beschleunigen und die Anzahl der Fugen zu reduzieren. Im Folgenden soll nun das Tragverhalten von zweifeldrigen Sandwich-Dachelementen unter Punktlasten, welche bspw. infolge von Photovoltaikaufbauten (PV) auftreten, numerisch untersucht werden. Hierzu werden Modellierungsvarianten für das auf Querdruck und Biegung belastete Mittelauflager sowie der Einfluss verschiedener Kerneigenschaften verglichen. Ziel soll es sein, die Querschnittsaktivierung infolge der lokalen Belastung zu quantifizieren und rein rechnerische Nachweise für PV auf Sandwich-Dachelementen zu ermöglichen. Numerical analysis of two-span sandwichelements with point loads Sandwichelements with thin-walled steel-faces and inner insulating core are the standard solution for the envelope of hall-constructions. The outer faces of wall-elements are usually lightly profiled, whereas roof-elements have at least one considerably profiled face. For a fast assembling with a minimum amount of joints, they are usually mounted as multi-span systems. In this article the load bearing behavior of two-span sandwichgirders exposed to point-loads, which occur due to top-mounted photvoltaic-systems (PV) for example, shall be discussed. Modelling examples for the middle support, which is stressed by vertical pressure and bending, and the effects of varying core-stiffnesses are studied. The goal is to determine the cross-section activation under point loads to advance design by calculation.
