COMPREHENSIVE STRENGTH AND DURABILITY EVALUATION OF 34-YEAR OLD POST-TENSIONED CONCRETE BRIDGE GIRDER. FINAL REPORT

The major objective of the research effort reported here was to evaluate the condition of a 34-year old post-tensioned bridge girder through laboratory testing. This evaluation included structural strength and serviceability, state of corrosion of prestressing elements (wires, ducts, and anchorates), material properties, and correlation of the condition of concrete and grout at various locations with the observed corrosion. In addition, the overall condition of the bridge from the corrosion standpoint was to be evaluated through a field condition survey of the bridge including non-destructive tests. The field surveys were sponsored by a separate FHWA project.
