The"Vertical springs" is active only when analyzing a floating pile. The input springs are displayed in the .
The option "input the stiffness of springs" requires inputting:
- spring at the pile base [MN/m]
- shear modulus of subsoil reaction along the pile [MN/m3].
The input values are the same for all piles. In the analysis the vertical stiffnesses of inner and outer piles in the group areby particular coefficients.
The option "Compute the stiffness of springs from soil parameters" requires inputting theto obtain the spring stiffnesses from calculation.
