Effects of Temperature Variations on Precast, Prestressed Concrete Bridge Girders girders. For example, girders are continuous, bending moments will be load, reinforcement in the deck girders provided negative moment capacity. 3. Design was based on a concrete block with a width equals the girder bottom
