The Effect of the Varied Temperature and Humidity on Creep Deflection in Service Stage of Bridges

Article Preview

The creep deflections in service stage of bridges are discussed with the effect of the variable temperature and humidity on creep. A coefficient of equivalent duration of loading (CEDL) is proposed, which is an indicator of the effect of the variable temperature and humidity. According to the periodicity of the climate and based on the recorded and collected daily average temperature and humidity in five cities in Pearl River delta from 2002 to 2006, the monthly average CEDL and the yearly average CEDL are thus given to study the effect of the variable temperature and humidity on the creep deflection of a five spans single plane cable-stayed bridge. It is demonstrated that the effect of the variable temperature and humidity is notable in the early phase but inapparent in the later phase of the service stage of the bridge.
