Study on Temperature Stresses in Concrete Box Girders Due to Heat of Concrete Hydration

Abstract:

The temperature distribution and strains due to heat of hydration of cement in a concrete box girder were measured on site during construction of the Harbin Songpu Bridge. The lateral and vertical temperature distributions and stresses in webs and slabs were analyzed. The study of the measured results shows that there are large temperature differences in the box-girder sections, and both the lateral and vertical temperature distributions and stresses are nonlinear. In some parts of the sections, the tensile stresses are even greater than the characteristic value of concrete tensile strength.
