New methodology for calculation of required prestressing levels in continuous precast bridge decks

The calculation of minimum required prestressing levels in prestressed bridge deck girders is usually governed by serviceability requirements in terms of allowable stress levels. In the case of continuous structures, different quantities of prestressing steels have to be quantified for different cri...
