Dynamic Performance Analysis of Reinforced Concrete Frames with Viscous Dampers Using Finite Element Modeling

This research evaluates the way that viscous dampers in Reinforced Concrete (RC) frames change the behavior of these structures, using FEA through ANSYS R18.0. The RC frame, configured using given dimensions and reinforcement layouts, was studied during dynamic simulations under earthquakes such as the Bhuj event. It was integrated into the frame using a stainless-steel piston and silicon-based hydraulic fluid to examine how the damper changed the structural behavior. Results from experiments were investigated to check the trustworthiness of the simulation model. Key findings show that a viscous damper cuts down lateral deflection by over 70% compared to a structure without the damper. Higher energy dissipation can be seen in the broader and larger loops shown in the load-displacement plots. Lateral acceleration was more balanced in the damped frame, confirming that it offered better handling and reduced vibrations. With these enhancements, RC frames become safer and more stable, proving again how viscous dampers handle the damaging impacts of shaking. The results emphasize the usefulness of dampers for strengthening and safeguarding RC buildings in earthquake zones.
