This study aimed to develop a decision-making support system for managing the seismic performance of aged road facilities in a road network, based on their evaluated seismic performance. This study was divided into two parts. In Part 1, seismic fragility functions are developed for bridges, tunnels, retaining walls, and slopes, while considering aging. In Part 2, the degradation of the seismic performance of the road network, along with social and economic resilience are evaluated based on these seismic fragility functions. The developed decision-making support system was applied to domestic test beds in Korea, and the results are discussed in Part 2. To develop seismic fragility, various ground motions suitable for the ground conditions in South Korea were generated. In particular, reduced- and real-size bridge piers and bearings were tested to study the effect of aging on seismic behavior. Other types of facilities, such as tunnels, retaining walls, and slopes, were also analyzed to study the same. For simplicity, representative facilities that can properly represent the seismic behavior of similar facilities were selected from a large number of facilities. The limit states for these representative facilities were defined, and their seismic fragility curves were calculated using these limit states.
