The constitutive behavior of hybrid basalt-polypropylene fiber-reinforced concrete (HBPRC) with different matrix strengths was investigated. The influences of basalt fiber (BF) and polypropylene fiber (PF) on the constitutive behavior and energy conversion relationship of the concrete were analyzed. The results show that the addition of BF and PF with an appropriate content can improve the ductility and strength of the concrete, but the influence of BF and PF on the elastic modulus is more complicated. In addition, the presence of BF and PF, especially their mixtures, significantly reduces the elastic strain energy release rate, increases the dissipation energy and thus improves the ductility and toughness of the concrete. Comparatively, BF is more conducive to improve the strength of the concrete, while PF mainly inhibits the expansion and penetration of macro-cracks in the concrete. Based on the statistical damage theory and dissipation energy, a constitutive model of HBPRC was proposed.
