In this work, the efficiency of four passive energy dissipation means, including viscous, viscoelastic, friction, and metallic yielding dampers, in high-rise building response was evaluated and compared. Conventional analyses and designs generally neglect the effects of soil and foundation flexibility. This effect is also considered in this study. First, a 20-story building with a steel moment frame was considered. Then, the nonlinear 2D model of this building is developed and subjected to nonlinear static pushover analysis to identify the floors that need a damper. The Response Reduction Theory method is used for this purpose. After designing each damper, four different models were replicated using viscous, frictional, metallic, and viscoelastic dampers. Each model was subjected to nonlinear dynamic analysis using ten far-fault ground motion records. The structural responses were extracted in the uncontrolled condition and in four controlled conditions with dampers. The results show that the metallic yielding and viscoelastic dampers have the best performance in reducing the structural responses than viscous and frictional dampers.
