Research Impact:

Bridges are an essential part of the transportation system in California and other parts of the United States. This is especially true during the period immediately following a major earthquake when the mobility of emergency responders is highly dependent on a functioning transportation network. As such, decisions regarding the structural integrity and functionality of earthquake-damaged bridges are a critical step in post-event response and recovery. The development of quantitative and comparable measures of aftershock bridge performance will ultimately lead to more informed post-earthquake decisions related to bridge closures, which has direct implications to the functionality and recovery of transportation networks.
