摘要：
Improved deformation history integral type hysteresis model (DHI model) is proposed. Original DHI model was elasto-plastic model and developed mainly for high-damping rubber bearings. While the model can represent the complex behavior of high-damping rubber bearings, there is an issue that the model cannot consider the performance change. Thus, the model was improved by defining the material parameters as a function of performance change ratio. In order to confirm the accuracy of the proposed model, time history analysis was carried out and compared the result of analysis with that of substructure real-time online testing system. © 2022 Architectural Institute of Japan.
