Decision inputs
- Seismic hazard level and response spectrum
- Capacity and travel demand
- Damping and re-centering targets
- Long-term service environment
APPLICATION SOLUTION
Construction seismic isolation & damping
Building and equipment seismic isolation devices use vertical disc spring groups and combined disc spring dampers for stiffness tuning and energy dissipation; this entry page lists design decision points and evidence entry.
ENGINEERING PROBLEM
Seismic and equipment vibration requires designable vertical stiffness, damping and re-centering behaviour.
BOUNDARY
This page describes a decision pattern and does not promise size or performance for another operating condition.
Solution pattern
- Disc spring groups form tunable vertical supports
- Combine with friction/viscoelastic elements for energy dissipation
- Configure stacking for re-centering targets
Key risks
- Over-travel and solidification under strong earthquakes
- Long-term creep shifts stiffness
- Instability under multi-axis input
Verification plan
- Stiffness and damping characteristic tests
- Quasi-static or shake table tests
- Durability and creep assessment
