The primary goal of this proposal is to enhance the resilience of coastal box girder bridges subject to storm and/or tsunami wave loading through an evaluation of their design geometry.  Specifically, the geometry to be studied is the angle of inclination of the web plates, the width of the bottom flange (where a width of zero implies a triangular form), and the integration of the rail/parapet as a structural element. The desired outcome would be to equip coastal bridge designers with resilient strategies for new coastal bridge designs as well as retrofit strategies of existing T-type and box type decks.

The intended outcome of the project is to equip coastal bridge designers with resilient strategies for new designs and retrofits of existing bridges.  This outcome will be disseminated in reports, papers, and oral presentations as described previously.
