Title:
Abstract:	Im Metallleichtbau wurden in den letzten Jahren dünnwandige Stahlprofiltafeln entwickelt, für die in den aktuellen Regelwerken keine Berechnungsverfahren existieren oder die Anwendungsgrenzen der bestehenden Verfahren überschritten werden. Im Rahmen des europäischen RFCS-Forschungsvorhabens GRISPE wurden umfangreiche experimentelle Untersuchungen an Verbunddeckenprofilen mit diskreter Sickung der Stege, perforierten Trapezprofilen, Fassadenprofilen mit Steckverbindungen, bombierten Profilen, Wellprofilen, Trapezprofilstößen und Kassettenprofilen mit direkt befestigter Außenschale durchgeführt. Es wurden ausgehend von bestehenden Regelwerken und Verfahren praxistaugliche Berechnungsverfahren abgeleitet. Der vorliegende Beitrag stellt auszugsweise die Ergebnisse für Kassettenprofile mit direkt befestigter Außenschale für Befestigungsmittelabstände, die normativ nicht oder nur unzureichend abgedeckt sind, sowie für statisch wirksame Überdeckungen, Trapezprofil-Überlappungsstöße und lokal verstärkte Trapezprofile dar. New calculation methods for thin-walled steel profiled sheets - Results from the European Research Project GRISPE. In recent years, thin-walled profiled steel sheets where developed in lightweight metal construction for which no calculation methods are available in current regulations, or application boundaries of existing methods are exceeded. Within the scope of the European RFCS Research Project GRISPE, extensive experimental investigations have been performed on composite floor profiles with discrete embossments in the webs, perforated trapezoidal profiles, façade profiles, curved profiles, corrugated profiles, trapezoidal joints and liner trays with directly fixed outer façade. Practicable calculation methods have been derived based on existing regulations and methods. This paper depicts in extracts the results for liner trays with directly fixed outer façade for fastener distances that are normatively not or insufficiently covered as well as for statically effective superimpositions, trapezoidal profile overlapping joints and locally stiffened trapezoidal profiles.
