） Abstract： In this study, the developed real-time substructure hybrid earthquake loading test system for verification tests of rubber bearings for highway bridges and viaducts is studied
A series of the fast/real-time substructure hybrid earthquake loading tests on NR (natural rubber), HDR (high-damping rubber), and HDR-S (super-high-damping rubber) bearings specimens are presented
The test system utilizes the concepts of the real-time pseudodynamic test method and the substructure technique to combine the loading process of rubber bearing specimens and numerical modeling of bridge column and girders
The objective of the development of the test system is to pursue accurate prediction of the seismic response and investigate the isolation effects of rubber bearings considering the loading rate effects subject to earthquake ground motion
