In bridge structures, column members are typically designed to be the primary source of energy dissipation during an earthquake. Therefore, reinforced concrete (RC) bridges that are damaged in an earthquake tend to have damage to the column members. While many studies have been conducted on seismic strengthening of RC bridge columns, most are focused on retrofit instead of repair. In addition, the limited research on seismic repair of RC bridges has focused on evaluating the response of individual columns (member level), not the bridge structure (system level), due to limitations in modeling and especially testing of full bridge structures. Local modifications (interventions) from the repair of a member can change its performance, and changes in column member performance can influence the bridge structure performance, especially under seismic loading. This study evaluated the impact of RC bridge column seismic repair on the member level, system level, and community level responses. Numerical simulation was used to model the response of repaired RC bridge columns (member level) and study the post-repair response of a prototype bridge with repaired columns (system level). The model was also extended to develop a methodology to minimize the level of pre-earthquake retrofit such that the RC bridge can withstand an earthquake without collapse, suffering minor or moderate damage that can be rapidly repaired later. Finally, a discrete-event-based simulation model was developed to estimate the time needed to bring the situation under control for a given volume of resources under a variety of scenarios after an earthquake occurs in a case-study community (community response), and to study the sensitivity of the restoration times to different variables.
