The main objective of the vibration separator is observing and reducing input energy, which lead to decreasing demand of energy loss in the main members of the structure. The vibration separator use the two following methods to reduce demand: increasing the the frequency time of structure and removing the force transfer way. Although, earthquake acceleration or displacement is used in designing of structure. However, the best variable to the effect of separator is speed. Based on the energy principle, there is a proportion between kinetic energy of an article and the square of the speed. In this study, two buildings without separator and damper and with frictional pendulum separator and non-linear viscose damper with tree records o Tabbas, Cape Mendesiona and North Rage are evaluated. The models are dynamically analyzed under simultaneous motivation of two horizontal earthquake elements. The northern-southern element of the used earthquakes in line to vector y and eastern-western elements of he earthquakes in line to vector x are applied on the models. The base shear, different floors and maximum acceleration structure of the building are criticized. The results show the amount of reducing maximum different floors is reduced as the friction coefficient increases.
