Abstract
To estimate whether the concrete could complete the preconcerted service function, based on the material science rule, this paper proposes a calculation rule to estimate the service life of the concrete under the freeze-thaw action. The relationship between probability distribution function of two-parameter Weibull distribution and percentage loss of relative dynamic modulus is deduced. The applicability of the freeze-thaw damage model of concrete based on the theory of probability and damage mechanics is demonstrated. And the equivalent freeze-thaw damage model of concrete is established, which could unify the results of the freeze-thaw experiment of concrete. The results show that the freeze-thaw damage model of concrete is appropriate to estimate the service life of the concrete structure.
