Abstract :
    viscous میراگرهای are generally used to control vibrations caused by wind in steel structures and with frequency bandwidth similar to the frequency of these controllers. The viscous flow is the set of passive control systems whose parameters are determined according to the initial dynamic characteristics of the structureand they remain constant . the main objective of this research is to observe the nonlinear behavior and performance evaluation of steel frames with a special steel moment resisting frame system equipped with viscous dampers compared to the uncertainties of mass and damping in the structure as well as elastic modulus and yield stress in steel . this assessment has been carried out with the help of multi - criteria decision - making and time - time analysis in sap and sap . for this reason , three structural , multi - criteria and multi - criteria structures with residential location have been considered .the results of this study show that drift and drift of the classes have changed drastically. Therefore, it is possible to conclude that the use of viscous damper is a good way to control the displacement of the structures. and the incidence of disturbance in the mass and damping of the structure than the other two parameters will have more effect on the structure response equipped with viscous damper.
