• Abstract:
  Many bridges along the Gulf Coast of the United States were damaged by recent hurricanes, and many more are susceptible to ; similar damage. This research examines the structural performance of common connection details used to anchor prestressed ; concrete girders to the substructure. Full-scale specimens were fabricated and tested under static and dynamic cyclic load ; histories. Dynamic load histories were developed from previously conducted hydraulic tests of a 1/5 scale model of a highway ; bridge under hurricane wave loads. The load effects considered included the pseudo-statically applied vertical uplift force, ; horizontal force, combined horizontal and vertical forces, and dynamically applied combined horizontal and vertical forces. ; This research describes the structural performance of the details under these loading conditions, provides improved ; understanding of connection performance, and enables better design details for new bridge construction and for rehabilitation ; of existing bridges to resist hurricane loads to produce surface transportation infrastructure that is more resilient to natural ; hazards.
