摘要
纤维混凝土中纤维充分发挥阻裂增强作用,采用有限元方法分析纤维的长径比、体积含量和纤维弹性模量的变化对纤维混凝土的界面剪应力的影响,并根据计算结果指出纤维的最优材料选型原则。
Fiber has the function of avoiding crack and increasing intensity in fiber concrete. In this paper, the author analyzes the influence of fiber's length-to-diameter factor, volume and elastic modulus on the interracial shearing strength of fiber concrete by finite element method, and points out the lectotype principle to select optimist materials of fiber according to the calculating result.
