【Abstract】 Because of heterogeneity of concrete, the probability statistics characteristics of strength of concrete material are discussed in this article. Damage mechanics is used to analyze the strength of the concrete material, and name strength of the concrete is calculated. Based on this, a new damage variable is defined. Size effect of the concerte strength is discussed qualitatively by using the concept of the damage variable.更多还原
