One of the methods that have been considered in recent years for the reinforcement of structures is the use of energy-absorbing systems. A variety of energy-absorbing systems have been developed and introduced, including liquid, viscous dampers. The main purpose of this study is to evaluate the efficiency of viscous dampers in absorbing forces caused by earthquakes and seismic improvement of structures and the feasibility of increasing the floors of an existing structure by using these dampers. Three different models with fixed plans and three different numbers of floors as five, nine, and thirteen have been selected for this purpose. The possibility of increasing one floor to them by using viscous dampers has been investigated. The results indicated that by adding a floor to the existing buildings, the stress ratio in some columns and the relative displacement exceeds the allowable limit; however, viscous dampers can significantly decrease the stresses and displacements and can be used to expand the number of floors of an existing building.
