Seismic vibration control of rc buildings using damper-integrated modified frame hear wall system

Earthquake-induced vibrations cause severe damage to reinforced concrete buildings, especially in high seismic zones. Conventional frame structures often fail to provide adequate lateral stiffness and energy dissipation capacity. This study investigates the seismic performance of a modified frameshear wall system integrated with viscous dampers for effective vibration control. Three building models, namely bare frame, frame with shear wall, and damper-integrated modified frame? shear wall system, were developed and analyzed using nonlinear time history analysis. Real earthquake ground motion records were applied to evaluate the structural response. The results show that the modified system significantly reduces storey displacement and inter-storey drift while improving energy dissipation capacity. The proposed system demonstrates improved seismic safety and can be effectively implemented in earthquake-prone regions.
