Coefficient of Influence of Pile Shape s
This coefficient represents the influence of a rectangular pile cross-section, the b/a ratio in particular. Its values are evident from the following graph (function of b/a):
Graph to determine pile shape coefficient s (a - length of the smallest side, b - the largest side)
For the NBN EN 1997-1 ABN standard, the shape coefficient s is defined as follows:
- for circular piles
- for square or rectangular piles
where: | a | - | shorter side of the pile base |
b | - | longer side of the pile base |
