A review of current design methods of axially loaded open ended driven steel piles in chalk is presented. Iberdrola pile testing campaign in Kent, United Kingdom, in low density chalk is described and selected results are presented. These include static axial uplift and compressive tests and a two-way cyclic load test on two 0.76 m diameter test piles. A comparison between actual and predicted pile behaviour with RATZ (load-transfer) computer program calibrated with direct simple shear Constant Normal Stiffness (CNS) cyclic laboratory tests is presented.
