uniaxial tensile constitutive equation simplified model high-ductility cementitious composites
In order to establish the constitutive relationship of high-ductility cementitious composites(HDCCs)under uniaxial tensile load and to guide the structural design of HDCCs, based on the analysis of the existing uniaxial tensile constitutive relationship and ideal elastoplastic linear strain-hardening model, a bilinear tensile constitutive equation of HDCCs was proposed. The points of nominal initial cracking and nominal maximum stress were adopted as control points of the line segment, and the constitutive relationship of HDCCs was established. Five series of uniaxial tensile stress-strain curves of HDCCs were combined to perform an experimental application of the constitutive equation, along with an analysis of the key parameters. The experimental results confirm the ability of the constitutive equation to overcome the problem of insufficient or excessive redundancy of existing models in terms of calculation bearing capacity. Specifically, the measured maximum stress value is larger than the nominal value, and the ratio between the two values ranges from 1.08 to 1.22. Additionally, the tensile strain at the softening point obtained by fitting a straight line with the valley points of the strain-hardening stage curve is greater than or equal to the tensile strain at the measured maximum stress point and the ratio of the fitted values to the measured values ranges from 1.00 to 1.19.
