Mechanics of rubber bearings for seismic and vibration isolation

Mechanics of Rubber Bearings for Seismic and Vibration Isolation collates in a compact form all of the information on the mechanics of the increasingly important technology of multi-layer rubber bearings. It explores a unique many ofthe results presented are new and are needed for a proper understanding of these bearings and for the design and analysis of vibration isolation or seismicisolation systems. The advantages afforded by adopting these natural rubber systemsotheir cost effectiveness, simplicity, and reliabilityois clearly explained to designers and users of this emerging technology, bringing into focus the design and specification of bearings for buildings, bridges and industrial structures.
