Abstract

Unter Verwendung des statischen Stabilitätskriteriums wird in Verbindung mit der Energiemethode eine spezielle stabbezogene Finite-Elemente-Formulierung entwickelt, mit deren Hilfe ideelle Biegeknick- und Biegedrillknicklasten von BSH-Bogenbindern bequem berechnet werden können. Wegen des geringen numerischen Aufwandes ist diese Formulierung hervorragend für Parameterstudien geeignet, die aufwendige Einzeluntersuchungen auf der Basis von zwei- oder dreidimensionalen FE-Modellen im Normalfall überflüssig machen. Die Ergebnisse einer solchen Studie an BSH-Kreisbogenbindern mit gebundener Obergurt-Kippachse werden im letzten Teil der Arbeit vorgestellt.
