This study compared the result applying two analysis methods based on Newmark Sliding Block theory to calculate permanent displacement that is an estimating factor for seismic safety of Fill Dam. It was analyzed FEM numerical coupled-analysis and Makdisi-Seed method. The permanent displacement for the body of dam during earthquake indicated similar displacements with each of them at the same seismic load.
