Analytical and Numerical Study of the Axial Stiffness of Fiber-Reinforced Elastomeric Isolators (FREIs) under Combined Axial and Shear Loads
Fiber-reinforced elastomeric isolators (FREIs) are rubber-based seismic devices introduced as a low-cost alternative to steel-reinforced elastomeric isolators (SREIs).They are generally used in unbonded applications, i.e., Clear Glass Can friction is used to transfer the lateral loads from the upper to the lower structure.Under combined axial and s
