Camber Prediction in Precast, Pretensioned Concrete Bridge Girders

Precast, prestressed concrete girders typically camber upwards when they are prestressed. If this camber is significantly larger than expected, smaller than expected, or if adjacent girders have significantly different cambers, construction problems can result. To reduct construction difficulties in the future,it is necessary to evaluate current methods for estimating camber and to improve these methods as necessary. The primary objective of the research is to improve methods of predicting camber in precast, prestressed concrete girders. The methods should address camber in all Washington State Department of Transportation (WSDOT) precast, pretensions girder sections with or without cast-in-place concrete slabs.
