Seismic reliability-based design of inelastic superstructures equipped with unbonded FREIs

Unbonded fiber-reinforced elastomeric isolators (UFREIs) are composed of elastomer layers reinforced with flexible fibers and are not attached to their upper and lower supports. UFREIs are an effective seismic isolation technology for low-rise buildings in developing countries due to their low manufacturing cost and lightweight properties. The study aims to establish seismic reliability-based relationships between the ductility-dependent …
