| 摘 要： | 针对钢纤维混凝土在单调载荷条件下损伤行为的复杂性，根据Weibull统计分布理论和等效应变假定原理，得出了钢纤维混凝土损伤本构模型，基于试验数据，确定了模型参数。分析计算结果显示，该模型可以有效地描述单轴受压状态下钢纤维混凝土的损伤过程。

| Abstract: | In light of the complexity of damage behaviour of the steel fiber reinforced concrete(SFRC) uniaxial compression,Weibull distribution phenomenological method and equivalent strain hypothesis theory were used to found the constitutive model of damage of SFRC.Based on experimental data,parameters of a constitutive model were established.The analytical results show that the given model can describe the mechanical capability of SFRC under uniaxial compression. |

| Keywords: | uniaxial SFRC damage damage variable constitutive model |
