Seismic events threaten the safety and functionality of lifeline facilities such as hospitals, data centers, and industrial plants. Protecting critical non-structural systems is essential, as they can represent over 80% of total earthquake losses. Building on recent triaxial shaking table studies of spring-mounted chillers (Awad et al., 2024), this work introduces a seismic isolation system combining induced tilting and viscoelastic fluid damping. The system, tailored for equipment below 10 tons, employs polyisobutylene fluid to provide low-frequency damping, enhance vibration control, and reduce seismic demand on vibration-isolated components.

摘要

Seismic events threaten the safety and functionality of lifeline facilities such as hospitals, data centers, and industrial plants. Protecting critical non-structural systems is essential, as they can represent over 80% of total earthquake losses. Building on recent triaxial shaking table studies of spring-mounted chillers (Awad et al., 2024), this work introduces a seismic isolation system combining induced tilting and viscoelastic fluid damping. The system, tailored for equipment below 10 tons, employs polyisobutylene fluid to provide low-frequency damping, enhance vibration control, and reduce seismic demand on vibration-isolated components.
