摘要
根据混凝土材料断裂过程区存在尺寸效应这一特点,结合断裂韧度尺寸效应公式对混凝土有效裂缝扩展长度做了相应的研究,得到了基于尺寸效应规律的有效裂缝扩展长度的表达式。运用该公式对已有试验资料进行分析比较,得出此公式适用于单直线软化模型,不适用于双直线软化模型的结论。
According to character of procession of concrete material having size effect, effective crack propagation of concrete crack was investigated with size effect formula of fracture toughness, and formula of effective crack propagation was obtained based on size effect rule. Using this formula to analyze some experiment result, some conclusions were reached that the formula waa suitable for single line soften model but not for double line soften model.
