evaluation of seismic behavior for different height of dam is important many embankment dams have been made in different height in our country that we have not general point of view about seismic behavior of them to achieve this goal masjed soleiman dam for a case study has been selected masjed soleiman zoned rock fill dam with 177 m height was constructed and impounded in south west of iran in 2001 finite element model of masjel soleiman dam has been constructed and the mohr-coulomb elastic -perfectly plastic constitutive model is taken into account to reflect the soil stress strain relation. first layer analyses have been carried out considering 12 layers in end of construction stage. then this analysis has been continued considering water table and weight of dam reservoir. 2 earthquake records have been applied horizontally to the bedrock for dynamic analysis. for study of mode of vibration and distribution of acceleration 10 models have been used with different height .
