This paper presents a simple approach to predict the buckling capacity of axially loaded partially embedded slender reinforced concrete pile using Davisson and Robinson method. The flexural stiffness (EI) equation of the slender concrete column permitted by ACI building code is adopted as such for concrete pile. Results of experimental investigations carried out on axially loaded slender concrete piles in sand medium for the various combinations of unsupported length and coefficient of subgrade modulus are compared with the proposed approach. The analyses indicate the nearness between the theoretical predictions and the experimental results.
