Estimating Bridge Girder Camber and Deflection

The purpose of this project is to improve the accuracy in estimating of camber and the long-term deflection of prestressed concrete girders. The project has three objectives which focus on evaluating concrete properties, measuring strand stress, and monitoring camber. The contribution of concrete properties and strand stresses to the variation in initial camber and long-term deflection will be assessed, a set of multipliers used to estimate camber at erection will be determined, and possible modifications of ARDOT specifications to accommodate the research findings will be proposed.
