Experimental and analytical study on ultimate property of rubber bearings: Proposal of material model to predict ultimate property and prediction analysis of break and buckling property for high-damping rubber bearings

Rubber bearing is one of measure isolation devices. Rubber bearings support upper structure under high vertical loading, therefore, it is very important to understand ultimate property and margin to the ultimate state to design seismically isolated structures properly. However, it is difficult to carry out ultimate property test using full-scale specimen because large scale testing machine is needed. One of the alternative method to predict performance of rubber bearings is analysis approach and finite element analysis is one of the most popular methods. Therefore authors propose analysis model to predict ultimate property of rubber bearings based on finite element analysis. © 2020 Architectural Institute of Japan. All rights reserved.
