The time-dependent increase of pile resistance is a known effect, which can be observed in cohesive and non-cohesive soils as well. In this contribution, approaches for the prediction of time-dependent increase of axial pile resistance are presented and compared with new field tests and project-related database results on precast piles in different soils. The aim of the evaluation is to develop a practical concept, for a reliable prediction of set up, which can be used as a tool for an a technically and economically optimized design of driven piles.
