Pile instability due to buckling is considered to be one of the most important causes of superstructures failures especially in bridges and wind turbines. The mechanism of load-transfer of partially embedded piles in sand subjected to axial load to surrounded soil and the corresponding deformation are important aspects of pile design. In the present research, an experimental model was developed to measure the lateral displacement of piles subjected to axial loads. The experimental results indicated that the post buckling load of partially embedded pile was enhanced up to five times of the buckling load of free case. Two proposed formulas based on the laboratory experiments were induced to determine post buckling load of the partially embedded pile. The predicted buckling capacity of piles was compared to the experimental buckling load, which showed a good agreement.
