Title:
Abstract:	Die Anforderungen an Tragfähigkeit, Verformungen und Rissefreiheit begrenzen die ausführbare Biegeschlankheit großformatiger Vorhangfassaden aus Textilbeton und erfordern monolithische oder metallische Aussteifungen. Ausreichend steife, tragfähige und dennoch leichte Querschnitte lassen sich mit Sandwichkonstruktionen realisieren, die zudem im Sinne der integralen Bauweise zusätzliche Funktionen in einem kompakten Querschnitt bündeln. Der Beitrag berichtet über die im Rahmen des Transferprojekts T03 des SFB 532 durchgeführten experimentellen Untersuchungen zum Tragverhalten von Sandwichquerschnitten unter Variation der Verbundmittel, der Dämmstoffe und der Betonschichtdicken unter Zug-, Schub- und Biegebeanspruchung. Sandwich façades made of Textile Reinforced Concrete - Experimental investigations. The demands on the load-bearing capacity and serviceability are limiting the applicable slenderness of large-sized ventilated façades made of Textile Reinforced Concrete (TRC) and thus monolithic or metallic bracings are required. Stiff, light-weight and at the same time capable sections can be realized with sandwich constructions that additionally offer structural-physical functions within a compact section. This contribution reports on the experimental investigations within the transfer project T03 of SFB 532 on the load-bearing capacity of sandwich sections with varying connectors, foam cores and thicknesses of the facings subjected to tensile, shear and bending forces.
