Thermal analysis of hydration heat in concrete structures with pipe-cooling system

The reduction of hydration heat and the prediction of temperature history i n massive concrete structures have been very important problems. In this st udy, a three-dimensional finite element program for thermal analysis of hyd ration heat in concrete structures with pipe cooling system was developed. A line element was adopted for modeling of pipe. Internal flow theory was a pplied for calculating the temperature variation of cooling water. The pred icted results were compared with the measured data from the spread concrete footing of the Seo-Hae Bridge in Korea. The predicted results showed good agreements with the site measured data.
