What the Researchers Did During Phase 1 of the project, researchers evaluated the current state of the art and practice relevant to continuous precast, prestressed concrete girder bridges and recommended suitable continuity connection details for typical Texas bridge girders. During Phase 2 of the project, researchers developed detailed design examples, conducted a parametric design study, and tested a full-scale modified Tx70 girder specimen containing three splice connections. Based on the findings from Phases 1 and 2, design guidelines and recommendations were developed for in-span splice connection details for use in continuous precast, prestressed concrete girder bridges.97
