Abstract:

This research investigates possible design-related causes of apparent shear cracks on MDOT prestressed ; concrete (PC) bridge girders; assesses the adequacy of PC shear design and rating methods; and ; recommends changes to these procedures. It involved a field survey, laboratory testing, FEA modeling, ; and bridge field testing. The field survey included sixteen PC bridges with potential shear cracks, and ; the shear capacities of the girders were analyzed and compared to various shear load demands. The ; laboratory testing consisted of six tests on full-scale beam specimens of different shear span-to-depth ; ratios and stirrup spacings. An FEA model was developed and validated using the experimental data. ; Using the model, a parametric analysis was conducted on a variety of PC bridge girder configurations. A ; regression analysis was performed to modify existing shear capacity procedures to best-fit the FEA ; results. Field tests of two PC bridges constructed continuous for live load were conducted to determine ; interior joint continuity and girder distribution factors.
