Temperature Gradient and Its Effect on Long-Span Prestressed Concrete Box Girder Bridge

Figure 13

The predicted transverse temperature distributions along the web of the girder for the four sunny days: (a) section T1 and the temperature on the outer surface of the eastern web reached a maximum value; (b) section T2 and the temperature on the outer surface of the eastern web reached a maximum value; (c) section T1 and the temperature on the outer surface of the western web reached a maximum value; (d) section T2 and the temperature on the outer surface of the western web reached a maximum value.
