Due to recent hurricane damage of bridges, emergency managers need to understand the potential state of the bridge network immediately following a storm for effective mitigation and post-event planning. To that end, this study builds a new database of bridge information necessary for vulnerability modeling, adapts current deterministic models of bridge deck uplift and scour for a probabilistic framework and expands the scour models to include a qualitative estimate for embankment scour. The study area bridges are tested under various hurricane scenario events to reveal the likelihood of damage. Potential applications include retrofit prioritization, real-time spatial damage modeling and better informed preparation. By understanding the risk hurricanes pose to the bridge system, emergency officials can better plan rescue and recovery efforts before a storm impacts the Texas coast.185 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
