AB  - This study aims to combine the structural and geotechnical aspects of the partially embedded slender prestressed concrete pile-soil system together to determine the buckling capacity of the pile. Three prestressed concrete specimens partially embedded in sand as foundation medium were tested with the combinations of unsupported length and coefficient of subgrade modulus of the sand medium under axial loading. In this study, a simple procedure to predict the buckling capacity of an axially loaded partially embedded prestressed concrete pile in sand is formulated using conventional Davisson and Robinson method combined with the ACI’s flexural stiffness equation of the slender column.  Comparison was also made between the theoretical predictions and the test results.
