Abstract

<p> The importance of a structural system with high robustness against seismic forces with high uncertainty has been shown, and such a structural system is required. Efforts are being made to realize a highly robust bridge structure by combining seismic isolation bearings and seismic dampers. In this study, we investigated the influence of characteristics of seismic isolation bearings and seismic dampers on the robustness of bridge systems using seismic isolation bearings and seismic dampers. It was found that characteristics of seismic isolation bearings and seismic dampers have a great influence on the coefficient of variation of the maximum response displacement of a pier and maximum plasticity rate.</p>
