ABSTRACT
In this study, we proposed the concept of resilience design for seismic damage to infrastructure and lifeline structures by extending the framework of the seismic damage estimation system for infrastructure and lifeline structures proposed in previous studies. Based on the resilience design system, a scenario-oriented analysis was conducted to estimate damage scenarios for road bridges damaged by the 2016 Kumamoto earthquake using three-dimensional finite element analysis. As input actions, surface fault displacement and strong ground motions were used, and damage scenarios were estimated for each seismic action and resilience design for these damage scenarios was examined.
