研究了钢筋约束聚乙烯醇纤维增强水泥基复合材料(Polyvinyl alcohol fiber reinforced cementitious com-posites ，简称 PVA-FRCCs )的单轴受压力学性能。通过抗压试验获得棱柱体试件的应力-应变全曲线，计算获得峰值应力\峰值应变\弹性模量等参数，并系统地分析了纤维体积掺量\掺合料(粉煤灰和硅灰)对上述参数的影响。此外，通过对试验数据和已存模型的比较，获得了一个能够描述其应力-应变全曲线的非线性本构模型。

The uniaxial compression property of polyvinyl alcohol fiber reinforced cementitious composites (PVA-FR-CCs) with steel reinforcement is analyzed. The stress-strain curves are obtained, the compressive parameters such as peak stress, average strain at peak stress, elastic modulus are calculated, and the effects of fiber volume fraction and admixtures (fly ash and silica fume) on the above parameters are studied. In addition, by comparing the experimental results with ex-isting models, a nonlinear constitutive models for describing stress-strain curves is achieved.
