This study is an evaluation on the seismic behavior of the Nahrain Dam, which is located in Khorasan province in the central part of Iran. The finite element method is used for the dynamic analysis of the dam. Using a slope stability computer program, the critical slip surface near the crest of the dam and the yield acceleration corresponding to this slip surface are determined. Static analysis was completed by using the finite element computer program SAP90 and SAP2000 in order to determine the stress conditions within the body of the dam prior to earthquake. The stresses obtained from this analysis were used in the assessment of the dynamic material properties of the dam. Two near by actual earthquakes were modified and used as input motions of different magnitudes. At the next step, the harvested data was used as input data for the program TELDYN to perform dynamic analysis. Permanent displacements under the scenario base motions were calculated by using the Newmark&rsquo / s method.
