Proposal of deformation history integral‐type hysteresis model considering performance change of high‐damping rubber bearings and verification using substructure real‐time online testing system for seismically isolated structure

Japan Architectural Review, 2023
A deformation history integral (DHI)‐type hysteresis model is an elastic–plastic model that was originally developed for high‐damping rubber bearings (HDRs). The model can show the complex characteristics of HDRs.
