High rise residential and commercial buildings are increasingly being constructed in urban areas of Turkey. Rock socketed piles are typically selected when large loads due to superstructures need to be transferred to competent bearing strata and restrict deformations within the serviceability limits of such structures. The axial load carrying capacity of rock socketed piles can be estimated utilizing various approaches: static analyses, information/data collected from pile load tests, numerical methods and empirical approaches that take into account the engineering properties of rocks surrounding the pile. In this study pile capacity of two rock socketed pile from Turkey were estimated using the finite element approach. A geometric model was constructed for the pile foundation which involved the pile diameter and length and the socketed length. The Mohr-Coulomb and Hardening Soil model was utilized to investigate the effective soil parameters. The load-displacement behavior from pile load tests were compared with those obtained from finite element analyses. © 2010 Taylor & Francis Group, London.
