Based on the theory of fracture mechanics and micromechanics of concrete, a flexural property prediction method for steel fiber PVA fiber reinforced strain hardening cementitious composite(SF PVA/SHCC) was developed by considering the effect of hybrid fibers on the flexural properties of strain hardening cementitious composite(SHCC). In order to verify the effectiveness of the proposed method, a series of flexural tests for SF PVA/SHCC were performed. The influence of fiber type and fiber content on the flexural strength, ultimate flexural deflection and load deflection curves of SHCC was studied. The results show that the proposed method can well predict the flexural strength and ultimate flexural deflection of SHCC containing steel fiber and PVA fiber.
