I would like to know if we are analysing and designing foundation of elevated centifugal machine supported on solid rock, (and no soil layer),
What are the soil spring constants to be used?
As rock is lava derived and foundation is kept after blasting, I presume there is no damping effect to be considered.
Secondly I think the soil spring cannot have tension but only can have enormous compression.
Do we have to anchor foundation in rock, --- hope not!!
The machine weight is aprroximately 900 kips and total foundation weight planned to be 4500 kips with approximately 4 ft thick mat.
We can use SAP 2000 non linear program to analyse.
Please suggest some ideas and if anyone has dealt this type of problem before then shed some more light how it was done.
Thanks.
