Soil Spring Constants input in Staad for Rocks
Soil Spring Constants input in Staad for Rocks
(OP)
Hi I would like to determine how to get the soil spring constants for rock foundations.
As I have only reference for Kfx/kfz determination for cohesionless/cohesive soils with N values.
Thanks in advanced!

RE: Soil Spring Constants input in Staad for Rocks
Also, a rock mass elastic modulus may be derived by the velocity of shear waves and that's most useful when you don't have a rock outcrop where you can carry out structural surveys.
Whenever I've done that, even very fractured rocks yield high values of the spring constant, so much so that rock can be usually considered a rigid constraint, unless of course loadings are very substantial
