Temperature Distributions and Stresses in Concrete Bridges

The paper is intended to give designers an understanding and visual appreciation of the way temperature distributions within bridge decks form and change throughout the day. Any temperature distribution is considered as a superposition of a steady state average heat flow between top and bottom surfaces and an hourly changing variation near the surfaces. Both components are analysed by classic theory of conductivity and can often be sketched by eye. The influences of surfacing and lightweight aggregate concrete are indicated. E.C. Hambly
