摘要：
Two kinds of fiber, which are steel fiber with high elasticity modulus and polypropylene fiber with low elasticity modulus, have been incorporated into concrete in order to improve its mechanical properties of low strain capacity. To study the impact of flexural strength of hybrid fiber concrete, in this paper, a meso-level numerical model of steel-polypropylene fiber reinforced concrete has been established. By changing the incorporation ratio of two kinds of fiber, the optimized ratio has been identified. The results indicate that when two kinds of fiber are added, brittleness of concrete has been significantly improved.
