Title:
Abstract:	Wenn repräsentative Bauwerke wie Botschaften und Flughäfen außergewöhnlichen Lasten aus Explosion ausgesetzt sind, dann kann das Ausmaß des zu erwartenden Schadens aus einer solchen Belastung durch den Einsatz von energiedissipierenden Schutzbauteilen in der Fassadenverankerung begrenzt werden. Bisher ist über das Tragverhalten solcher Schutzbauteile wenig bekannt. In diesem Aufsatz werden Konstruktion und Wirkungsweise einer Verankerung für vorgehängte Fassaden vorgestellt, die in der Lage sind, einen Teil der Stoßenergie über Verformung eines Crashmaterials zu dissipieren. Versuche an einer bauteilähnlichen Konstruktion liefern Informationen über das Tragverhalten der Fassadenverankerung, insbesondere bei dynamischen Belastungen. Aus den Ergebnissen wird ein Konzept für die Vordimensionierung der vorgestellten Schutzbauteile abgeleitet. Energy dissipating protective component for façade connectors of buildings under impulsive blast loads using crash material In the past few years public awareness of the need to protect structures against blast effects has risen. Blast wave energy is transmitted to the supporting structure by its façade connectors. Energy dissipating protective components placed at the connectors allow protecting people in the building as well as the primary building structure from damage. In this paper we present a protective component that dissipates blast energy by crash material. The report explores the system's fundamentals of operation from an experimental point of view. The results of dynamic tests are the basis of a design concept for the protective components.
