Comparison of Strengthening Solutions with Optimized Passive Energy Dissipation Systems in Symmetric Buildings

The aim of this study is to compare the seismic response of reinforced concrete (RC) symmetric buildings, with a varied number of stories, strengthening with three types of passive energy dissipation systems, as tuned mass dampers, viscous dampers, and friction dampers. The paper presents an overvie...
