The buckling of slender piles under complex loading

Tests on model steel piles fully embedded in a soft silty clay have indicated that the elastic buckling load is a function of the imperfections of the pile or the eccentricity of loading. The elastic buckling load of a pile loaded eccentrically was found to be as low as 19 per cent of the buckling load of the same pile when loaded axially. This decreasing load capacity with eccentricity is a direct result of the non linear nature of the stress strain properties of the soil used in the experiments. Similar effects can be expected in the soft soils where the possibility of buckling must be considered. A theoretical investigation of this problem indicates that the maximum reduction in the elastic buckling load would be between one quarter and one sixth of the elastic buckling load of an axially loaded pile (A).
