2256 - Understanding the Behavior of Prestressed Concrete Girders After Years of Service

The proposed project consists of a comprehensive study including both testing and analysis of two real-world American Association of State Highway and Transportation Officials (AASHTO) Type II girders to be obtained during replacement of the I-244 bridge over the Arkansas River in Tulsa after about 47 years in service. It also includes detailed study of composite action in the form of testing the real-world girders and a scaled composite bridge section. This research will provide critical supplemental information to and improve upon previous research focused on the shear capacity of one real-world girder sponsored by the Oklahoma Department of Transportation (ODOT) at the University of Oklahoma and answer numerous questions concerning bridge girders put into service during the same time period. It will provide detailed information concerning composite behavior of prestressed girder bridges critical to shear. It also has the potential to provide opportunities for a significant quantity of additional research during the process of determining shear capacity and studying prestress transfer. The results of this research would be used to evaluate the condition and safety of prestressed concrete girders designed for shear using the quarter-point rule described in the AASHTO Standard Specifications (AASHTO 1973) in comparison to the current AASHTO Load Rating Factor Design (LRFD) Specifications (AASHTO 2004). Additionally, improved procedures for using nondestructive methods to determine condition of in-service structural members would be recommended.
