Shear Strain Demands in Elastomeric Bearings Subjected to Rotation

In seismic base isolation applications, fiber reinforcement was initially proposed as a potential cost-saving alternative to conventional steel reinforcement in laminated bearings. Steel reinforcement is often assumed to be rigid, but the extensibility of the reinforcement serves as an additional design parameter that must be considered. Similar to the compressibility of the elastomer, the extensibility of the reinforcement has a pronounced …
