Correction Factors for Driven Piles
The correction factors for base ηb and shaft ηs may be calculated or input for driven piles in the "Geometry" frame.
Pile type | ηb [-] | ηs [-] |
Reinforced concrete and prestressed concrete | 1,00 | 1,00 |
Steel tube - open (0,30 m ≤ Db ≤ 1,60 m) | 0,95.e-1,2Db | 1,1.e-0,63Db |
Steel tube - closed (Db ≤ 0,80 m) | 0,80 | 0,60 |
where: | Db | - | equivalent pile base diameter [m] |
