Vibration control of structure using inelastic tuned mass damper
Currently, earthquake-resistant design standards are based on the expectation that structures will undergo inelastic behavior during major seismic events, often resulting in ductile behavior with notable damage in steel and reinforced concrete buildings. Passive control systems are commonly employed to shield buildings from earthquake-induced damage. This study focuses on examining a building with a top floor serving as a tuned mass damper (TMD) through base isolation. The top story acts as the TMD, with an isolation system placed at the bottom of this upper floor. Made of concrete, this TMD possesses the same damping ratio as the primary building structure. The effectiveness of this Base Isolated TMD is assessed by comparing analysis results obtained through Time History Analysis. This comparison reveals that the Base Isolated TMD significantly enhances the building's seismic performance when compared to a structure lacking a TMD.
