dear, can anyone help me to find my mistake i tried to model linear soil and nonlinear, there no change in displacement both are the same.

i fixed the soil now i have the compilate model for SPSS, but i have problem with the vertical displacement is zero can you help me to find the mistake

Thank you for the feedback.
Regarding the issue: I noticed that the input acceleration at the base and the output (recorded) acceleration at the same location are not identical. My understanding is that for a correct implementation of the boundary conditions, the input motion and the response at the ...

hello dear, i am working on the effective of vertical earthquake and i am modeling the soil the problem is the input and output at base not the same i try to reduce mesh, but same things, can you help me to solve this?

hello, can you help me to find out why the analysis take more than 10h to finish.
