Effects of Humidity Field on Creep of Reinforced Concrete Beams
Creep, as one of the most important properties of concrete, has important influences on concrete structures. In present domestic researches, studies on humidity diffusion in concrete are relative inadequate; and few models can take comprehensive consideration on humidity factors. According to humidity diffusion theory of concrete, this paper studied the distribution of humidity field within concrete at constant humidity condition by using finite element method. Based on the drying creep of the Model B3, this paper analyzes the effects of humidity field on creep of RC beams.
