Effect of the Hydration Heat on Creep

Abstract:

A method for the box girders creep calculation considering the hydration heat is proposed and the effect of the hydration on the creep is discussed. The box girder is divided into several components and the average hydration temperature of the component is defined to represent the general condition resulted in the hydration. The formulae of the average hydration temperature have been recommended based on the discussion with respect to the formulae accuracy. The effect of the hydration on the creep is changed into that of the variable age of loading and the relationship between them is also given. It has been found that the hydration decreases the creep stress obviously.
