WAVE FORCES ON CAUSEWAY-TYPE COASTAL BRIDGES

A 1:24 scale model of the Bay St. Louis, Mississippi bridge was used for the determination of lift and drag forces and rolling moment caused by normal incidence waves. The bridge was damaged by Hurricane Camille in 1969. The Bay St. Louis Bridge is a causeway-type, four-lane bridge of beam and slab construction. Pairs of lanes are structurally separated. Wave forces and moment were determined separately for the seaward and landward pairs of lanes. Thirty pages of design curves are presented in dimensionless form for scaling to prototype dimension. The study was made more applicable to other bridges of similar geometry by varying the height of the bridge deck above the bay bottom. Results predict observed anchorage failure in the Bay St. Louis bridge.
