Abstract

 Since Hyogo-ken Nanbu Earthquake in 1995, many laminated rubber bearings have been installed because of horizontal force dispersion or seismic isolated design. Although some rubber bearings with long period in service are reported several damages caused by aged deterioration, it is not clear about the bearing performance and most damaged bearings are remained as it is. In this study, the authors carried out the load test and the material test using some aging deterioration damaged lead rubber bearings, in order to verify the remaining performance. As a result, it turned out that the bearing stiffness was increased and seismic damping performance was reduced caused by aging deterioration of natural rubber and lead.
