Research: Evaluating Seismic Resilience of Reinforced-Concrete Frames with Combined Bas...

Research question: How does the integration of base isolation and tuned mass dampers affect the seismic resilience of reinforced-concrete frame structures compared to conventional mitigation strategies?

Background & Motivation: Earthquakes pose significant risks to reinforced-concrete (RC) frame structures, often resulting in extensive economic losses and casualties. Modern seismic protection techniques like base isolation and tuned mass dampers (TMDs) have shown promise in reducing structural damage and improving occupant safety.

Research Gap: While both base isolation and TMDs are individually studied, limited research exists on their combined effectiveness in enhancing seismic resilience for RC frames, especially when compared systematically to conventional seismic design approaches.

Approach & Expected Contribution: This project will conduct a comparative analysis using numerical modeling and time-history simulations in OpenSees or SAP2000, applying real earthquake ground motion records to RC frame models equipped with base isolation, TMDs, and their combination. Performance metrics such as inter-story drift, acceleration, and residual displacement will be evaluated.

Why It Matters: The findings will inform civil engineering practice by quantifying the potential benefits and limitations of integrating base isolation and TMDs, supporting evidence-based decisions for resilient infrastructure design in seismic regions.
