BRIDGE TEMPERATURES DERIVED FROM MEASUREMENT OF MOVEMENT

Movements were measured at expansion joints in 7 bridges of various forms of construction and were transformed into corresponding values of effective bridge temperatures. Correlation was established between these effective temperatures and the sum of the mean shade temperature of the five previous days and an appropriate proportion of the daily range of effective bridge temperature. From this, both the annual range and instantaneous values of effective bridge temperature can be determined. The method also enables statistical estimates to be made of the range of effective bridge temperature for various return periods. The influence of bridge exposure, geographical location and bridge form on effective bridge temperatures are also discussed.
