Abstract: Mechanical properties of hybrid fiber reinforced strain hardening cementitious composites (HyF/SHCC) have been one of the hot topics in recent years. However, there is still a lack of in-depth discussion on the constitutive relationship of HyF/SHCC in compression. In this paper, the full compressive stress-strain curve of HyF/SHCC containing steel fiber(SF) and polyvinyl alcohol (PVA) fiber was investigated. The compressive strength, strain and toughness of SF-PVA/SHCC were discussed. The results indicate that the introduction of hybrid fibers has no significant effect on the compressive strength of SF-PVA/SHCC in this case, but it increases the corresponding strain at peak stress. The effect of SF on the compressive toughness of SF-PVA/SHCC is significant. The compressive toughness increases gradually with the increase of SF content. Based on the theory of damage mechanics, a new uniaxial compression constitutive model was proposed from the perspective of energy. Through the comparison with the experimental curves, it was found that the proposed model could well predict the compressive stress-strain relationships of SF-PVA/SHCC.
