Phenomenological modeling of fiber‐reinforced elastomeric isolators at multiple lateral deformation levels

Abstract Unbonded fiber‐reinforced elastomeric isolators (FREIs) are a cost‐effective seismic isolation technology that uses lightweight fiber‐fabric reinforcement and forgoes the attachment plates connecting the isolators to the supports. These devices exhibit a complex nonlinear mechanical behavior under lateral deformation, which has typically been represented by uniaxial phenomenological models. In this paper, a new model, called Pivot …
