| Abstract: | Determination of critical buckling loads of columns in a medium which offers resistance to lateral deflections depend on:- (a) Length of the pile, L.
- (b) Flexural stiffness of the pile, EI.
- (c) Stiffness of the soil, K, and
- (d) Boundary conditions of the pile, both at the top and the tip.
In this paper, solutions for buckling loads have been obtained in closed form by energy methods for fully embedded vertical piles for boundary conditions, pinned top-pinned tip, fixed top-fixed tip, and a linear variation of soil stiffness. The effects of pile length, soil stiffness, and boundary conditions on buckling loads and mode of buckling have been studied for pile lengths up to 24 m with EI of 477 tm2, K0 A] from 0 to 2000 t/m2 and Nh B] from 0 to 2000 t/m3. |
