Title:
Abstract:	Bei der Bemessung von Stahlbetonbauteilen gegenüber Explosionsereignissen werden zurzeit lediglich subjektive oder pauschale Sicherheiten berücksichtigt. Es ist zurzeit ungeklärt, welche Sicherheit für diese besondere Belastungsart innerhalb der Bemessung gewährleistet wird. Es wurde ein an Stoßrohrversuchen validiertes Einmassenschwinger-Modell mit Zuverlässigkeitsanalysen erster Ordnung verknüpft. Diese Verknüpfung erlaubt es, die vorhandenen Sicherheiten innerhalb der Bemessung zu ermitteln. Die Ergebnisse belegen ein Defizit innerhalb der Auslegung hinsichtlich der nach Eurocode 0 (EC0) geforderten Zuverlässigkeit. Reliable design of reinforced concrete plates against explosive actions in accordance with the Eurocode Within the design of reinforced concrete against explosive threats only a subjective or a lump safety is currently considered. Therefore the established safety is unknown. For the estimation of the existing safety of present approaches the SDOF approach has been linked to the first order reliability method, which allows for a derivation of the given reliability. Hereby it could be proven that the considered safety is, compared to the claimed reliability of the Eurocode (EC0), deficient.
