3 EUROCODE Safety Approach as Applied to Single Piles
E. Franke Technical University Darmstadt, and Franke-Meibner-Consultants, Wiesbaden-Delkenheim, Germany
First the limit state design regulations are explained. Then their application to single piles is shown using conventional deterministic or global safety factors. The result is that separate safety factors for base and shaft resistance are not applicable. Only one global safety factor F applied to the sum of the shaft and base resistance forces as usual up to now proves to be reasonable. At last it is shown that the same result reveals when partial safety factors according to the Eurocodes are applied, i.e. the application of F = Y is justified. No change in daily practice is necessary considering single pile bearing behavior.
