Outline of Final Research Achievements

Performance of rubber bearings can be deteriorated, and cracks and rupture of rubber bearings occurred during the past seismic events. A fundamental research was conducted to realize isolated bridges which can be in operation immediately even after large earthquakes. It was shown that rupture of isolators can be prevented and that isolated bridges with high seismic safety and high reparability can be realized by ensuring the appropriate capacity ratio between isolators and bridge columns considering deterioration of isolators.
