Synthesis of available methods for repair of prestress girder ends

Many bridges in the Unites States are aging and due for repair or strengthening. Corrosion of prestressed girder ends is a prevalent problem that significantly reduces the bearing capacity of bridges. Moreover, over-height vehicles continue to collide and impact bridge girders around the country, which compromise the flexural capacity of bridge girders. Several research studies and state DOTs initiatives looked into innovative repair and strengthening methods for girders end zones and/or mid span impacts. The goal of this project is to synthesize the available literature on bridge girders repair methods with focus on prestressed girders and end zones damage. The synthesis will summarize and compare the design and application procedure of different methods to provide a guide or catalog for bridge engineers working on girders end repair.
