Time Dependent Deformation in Prestressed Concrete Girder: Measurement and Prediction
Prestressed concrete girders which are intended for composite construction in bridges and other similar structures are often stored unloaded for some time before being placed in their final positions where top deck is being poured over. During that free storage the girders are subjected to creep and shrinkage which manifests itself through increased upward deformation usually defined as camber. The analytical estimation of this deformation is important as it controls the minimum thickness of the top deck. In this paper an attempt was made to correlate on site measurements with continuous computer modelling of the time-dependent behavior using data from recently adopted international standard for concrete structures.
