Using precast girders for the superstructure allows for better construction tolerances and quicker construction methods. The purpose of this study is to develop and examine integral connection details between precast U-Girders and cast-in-place substructures subjected to longitudinal seismic loading. Analytical modeling and experimental cyclic testing of four, 40 percent precast U-girder specimens are used to investigate the behavior of the connections. This study primarily investigates the effect of post-tensioning on the connection performance. Analytical and experimental results show benefits to longitudinal post-tensioning in respect to joint detailing and system continuity which aren’t considered in current design methods. Additionally, potential local joint cracking problems need to be addressed in joint design methods.
