Abstract

 Considering the possibility of occurrence of earthquake motion exceeding the design earthquake motion, we developed a collapse scenario design method. It realize the seismic performance that has been ensured through the conventional seismic design of road bridges, and the function is kept as much as possible, or the function can be recovered quickly against excess motion. In this method, we can select a more desirable scenario by showing the damage mode of the bridge according to excess motion level. We showed how to realize the design of the bridge against the maximum seismic motion by controlling the rupture likelihood after considering the various strengths of the structural elements of the bridge.
