soil structure interaction
(OP)
Hiii
I am working on soil structure interaction using SAP2000.
First, i made a model included 5 story with fixed end and compute the displacement.
second, i used the same model but i used springs instead of fixed joint and compute the displacement.
is it true to make this to determine the SSI effect???

RE: soil structure interaction
That question does not have a yes/no answer. If your springs are a reasonable representation of the soil stress/strain behaviour, then yes, if not, no.
Deciding if the springs are in fact a reasonable representation of the soil is the difficult bit.

RE: soil structure interaction
Is it represent the soil and foundation ??
Is it represent the dynamic stiffness and damping ??
How did you calculate the spring's stiffness??
RE: soil structure interaction
Kx, Ky,Kz
So i used SAP2000 like this
Assign/joints/springs / i included Kx and so on
