Creep design according to EN13445-3 Annex B

摘要

Creep design according to Annex B of EN13445-3, "Design by Analysis Direct Route", is based on nonlinear analyses with linear-elastic ideal-plastic material law. The Creep Rupture check, the Excessive Creep Strain check, the check for action cycles without plastification, and the applied method for creep fatigue damage accumulation are summarised. To get a better insight, the relation to different reference stress methods, on which the checks are based on, are explained.
