Long-term study on bearing restraint of a girder bridge

Bridges in regions where temperature range between seasons is large are affected significantly by the temperature range. The temperature affects bridges in different forms, one of which is the reactions that they develop in the bottom flanges of girders against the horizontal movement. Bearing restraint due to temperature change was studied in two bridges in the province of Manitoba, Canada. The study results presented in this paper show that the bearing restraint forces are not negligible.
