ABSTRACT
Since the introduction in the 70’s of screw piles of the displacement type, numerous pile loading test programs have been performed in various soil conditions. From these, 27 pile tests are selected and reported. For the sake of clarity, completeness and to allow in the future for a systematic and uniform interpretation and analysis, a test data base format has been elaborated and applied. The A4-sheet aims to include clear information on soil conditions, pile data and pile test. An overall normalized load-displacement behavior resulting from the selected test data is included in the paper.
