Seminar Series- Functional Recovery of Bridge Networks: Framework Development and Implementation

While building post-earthquake functional recovery assessments has made significant progress, comparatively, the advancements on this topic for bridges have thus far been less fruitful. This is partially due to the absence of a systematic and unified procedure, coupled with the lack of a well-organized data and information set that supports such assessments. This presentation will focus on a methodology for evaluating bridge post-earthquake functional recovery that can be implemented at multiple scales (i.e., individual bridge and/or network). The framework is comprised of three modules that probabilistically evaluate the functionality state, impeding factor time delays and repair or replacement durations. It is supplemented by expert opinion-based data and information from interviews with bridge engineers, engineering managers, and contractors. The framework is implemented on a bridge network encompassing local and state-owned bridges in the City of Los Angeles. The proposed model supports the development of seismic retrofit programs and decisions related to post-earthquake inspections and repairs.
