Seismic Performance of Reinforced Concrete Frames with Dampers

The seismic performance of reinforced concrete (RC) frames is crucial for ensuring structural safety in earthquake-prone regions. Traditional RC frames often suffer severe damage during seismic events due to their brittle failure modes and inability to dissipate sufficient energy. In recent years, structural dampers have emerged as an effective method to enhance seismic performance by reducing vibration responses and increasing energy dissipation. This paper investigates the role of passive dampers, particularly viscous and friction dampers, in improving the seismic performance of RC frames. Analytical and experimental studies are reviewed, along with numerical simulations, to evaluate the reduction in displacement, inter-story drift, and base shear. The paper concludes that the integration of dampers significantly improves the resilience of RC frames, offering a cost-effective retrofitting solution for existing structures.
