Popis:	In practice, evidence suggests that long, slender piles subjected to axial loads can fail under axial stresses below the yield point of the pile material. A general solution for critical buckling capacity of long, slender friction piles in clay is presented using the minimum potential energy method. The Rayleigh-Ritz method is adopted to select deflection functions satisfying six geometric boundary conditions encountered in practice. Parameter studies were performed to investigate the buckling response of fully and partially embedded piles and the effect of pile-top and tip conditions on buckling capacity. Results indicated that the boundary conditions at the pile tip have no effect on the critical buckling capacity in cases in which the nondimensional embedment length (\Ih\N’) exceeded a critical value. In addition, for fully embedded piles, the effect of embedment length was nearly negligible after \Ih\N’ exceeded a value of 6 for fixed-with-sway pile-top conditions.
