Probabilistic finite element analysis of high strength steel structures
conference paper
In structural steel design the ultimate design limit is governed by full cross-sectional plasticity, where an elastic-perfectly plastic material behaviour is used. Hardening of the material is not used. Some loads are not considered such as settlements of supports and temperature loads in static indeterminate structures. The Stochastic Finite Element Method (SFEM) has been developed and used to investigate whether the hardening of the material can safely be utilised in the design calculations, still neglecting the above mentioned loads. The conclusions drawn from the SFEM calculations are that the amount of hardening that can be utilised depends on the kind of steel material (a-e diagram). For high strength steel structures the hardening can hardly be used (without including the above mentioned loads). For normal steel the amount of hardening to be utilised depends on the load case.
