The study of seismic isolation systems has markedly advanced in recent decades, offering innovative pathways to shield structures and sensitive equipment from earthquake-induced forces. At its core, ...

In analysis, it is common practice to conceptualize structures, objects, and isolation systems as basic mass-spring-damper models, as depicted in Figure 42.1. All objects experience vibration when ...

Earthquakes cannot be forecast, but engineers can prepare for them. Seismic-isolation systems built into the bases of certain buildings in high-risk areas, such as San Francisco’s City Hall, use ...
