Eurocode EC-7 Part l “Geotechnical Design – General Rules” will soon be coming into force. The geotechnical design safety analysis incorporated into this standard refers to limit state methods and adopts a semi—probabilistic approach, whereby safety is ensured by means of partial safety factors and design values for actions, material properties and geometrical data. The code makes it possible to determine the design load of driven precast concrete piles by means of dynamic pile formulae, but does not establish any value of partial safety factors.
Eurocode EC-7 Part l “Geotechnical Design – General Rules” will soon be coming into force. The geotechnical design safety analysis incorporated into this standard refers to limit state methods and adopts a semi—probabilistic approach, whereby safety is ensured by means of partial safety factors and design values for actions, material properties and geometrical data. The code makes it possible to determine the design load of driven precast concrete piles by means of dynamic pile formulae, but does not establish any value of partial safety factors.
In this paper, the values of bearing resistance deriving from the use of pile driving formulae have been compared with those measured with in situ loading tests of precast concrete piles; values of partial safety factors have been estimated using several diilerent methods to determine a failure probability of about 3, which represents a key reference value in geotechnical foundation design. In addition, the paper examines whether the use of a bayesian data processing method may be helpful in the determination of the numerical value of partial safety factors.
