What Is a Seismic Isolation Test System?
A Seismic Isolation Test System is a specialized servo-hydraulic machine used to test seismic isolators under combined vertical and horizontal loads. These systems reproduce real earthquake movements, allowing engineers to measure stiffness, damping, hysteresis behavior, displacement capacity, and long-term durability.
Seismic isolation technology is widely used in:
- Hospitals
- Bridges
- High-rise buildings
- Airports
- Nuclear facilities
- Data centers
- Historical monuments
Why Seismic Isolation Testing Is Essential
