摘　　要：研究了钢纤维混凝土一维拉伸时的损伤行为 ,建立了损伤演化方程及损伤本构方程 ,并根据钢纤维混凝土一维拉伸试验曲线得到了损伤参量D的变化规律 。When one dimensional tensioning steel fiber reinforced concrete its damage behavior is researched. And damage evolution equation and damage constitutive equation are determined. According to the curve of one dimensional tension test the changeable law about damage parameter D is obtained. A rectangle model predicting change of material Poisson ratio in terms of damage behavior is put forwards.
