Abstract

Abstract

Based on Moelands-Reinhardt single parameter exponential constitutive equation,steel fiber concrete damage development equation is obtained using equivalent strain hypothesis.Modified damage development equation of steel fiber concrete is proposed for eliminating mesh correlation of element characteristic length and reflecting the action of tensile strength and fracture energy on the damage development equation.The modified damage development equation comprehensively reflects the action of steel fiber volume ratio and aspect ratio on damage development.Relation of displacement force is obtained by splitting test and theoretical relation of displacement-force obtained by damage FEM calculation.Through comparison of empirical D-P relation and theoretical D-P relation,damage development equation of steel fiber concrete is verified in this paper.
