摘要
在实验观测基础上，提出了钢纤维混凝土裂端微裂区耗能模型，结合断裂分析中的能量平衡和耗散原理，运用该模型定性定量地分析和解释了钢纤维混凝土疲劳损伤行为的内在机理。
An energy dissipation model of microcrack tip zone of steel fibrereiforced concrete is introduced based on an experimental investigation。Applied the model and the Energy Equilibrium and Dissipation Theory,thequalitative and quantitative analyses and interpretation on the mechanism offatigue damage performance of steel fibre reinforced comcrete are carried outin the paper.
