Non-uniform temperature distributions in concrete bridges are caused by diurnal changes in the environment. These and other thermal effects are of major concern to bridge design engineers. This paper presents a numerical method of analysis of the temperature distribution. Considered are the environmental interaction, the material properties and the structure characteristics. A parametric study was developed to obtain design temperature differentials for typical bridge cross sections. The method was also applied to the study of special cases, some of which are presented as examples.
