Research Abstract

In this research, a real-time substructure hybrid experiment system was developed. This system enables the dynamic loading test of the bearing, considering the dynamic interaction between girder and pier. A 2DOF hybrid tests assuming the pier, bearing and girder were carried out using the developed loading system, in order to comprehend the behavior of the rubber bearing under earthquake excitation. It was confirmed that the dynamic characters of the bearing was experimentally obtained, considering dynamic interaction between structure and bearing.
