I am trying to replicate the equivalent linear analysis inAbaqus . In case of Deepsoil we need to provide G/Gmax and damping ratio with respect to strain curves in Abaqus software and carry out the time history analysis. I am currently having G/Gmax and Damping ratio curves. Can u please tell me the procedure to perform ground response analysis in Abaqus software similar to equivalent linear model analysis in Deepsoil.
