Analysis According to the Theory of Limit States
When performing the analysis according to the theory of limit states the program carries out the verification analysis for a pile group in a cohesionless soil:
where: | Rg | - | vertical bearing capacity of a pile group |
n | - | number of piles in the group | |
Rc | - | vertical bearing capacity of an isolated pile (Rb + Rs) | |
γt | reduction coefficient of total resistance | ||
ηg | - | ||
Vd | - | maximum vertical force (including the pile cap self-weight) | |
Wp | - | self-weight of piles (only when the option "Consider the self-weight of pile" is checked) |
When performing the analysis according to the theory of limit states the program carries out the verification analysis for a pile group in a cohesive soil:

Vd | - | maximum vertical force (including the pile cap self-weight) | |
Wp | - | self-weight of piles (only when the option "Consider the self-weight of pile" is checked) |
γt | - | reduction coefficient of total resistance |
When performing the verification analysis according to EN 1997-1 the pile group vertical bearing capacity in a cohesive soil is reduced by the coefficient of base resistance (γt = γb).
