Prästings, A., Spross, J. and Larsson, S. Characteristic values of geotechnical parameters in Eurocode 7. ICE Geotechnical Engineering , Ahead of Print. doi.org/10.1680/jgeen.18.00057

This paper discusses how uncertainties are managed according to EN 1997-1:2004 and possible implications of not harmonising the current safety format with reliability-based design. One of several challenges highlighted is how EN 1997-1:2004 defines the characteristic value and design value. The definitions of the characteristic value and design value in EN 1997-1:2004 feature weak connections between uncertainties in the geotechnical properties and the consequences of failure, as regulated by the target reliability index.
