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 ...

The main objective of this project is to develop and test a phased damping device, or “gap damper”, to act alongside a base isolation system for buildings or bridges. The gap damper provides ...

Traditional isolators are built with metal springs or rubber blocks. They have low internal damping and generally are only effective at frequencies near 10 Hz. They also offer little to no isolation ...
