Can I run a simple 2D dynamic model with dummy pile in SACS?
SACS is a 3-dimensional analysis program and will always operate in 3D, but you can restrain one dimension using boundary conditions to make it "2D". Pile foundations are inherently nonlinear and SACS uses a linear modal dynamic analysis so the foundation must be linearized for dynamic analysis. You can linearize the piles using the Create pilehead superelement analysis in SACS. Read section 2.5 of the PSI/PILE manual for more information about this process.
