摘　　要：混凝土的单轴受压应力-应变曲线方程是其最基本的本构关系,在钢筋混凝土非线性分析中有着重要作用。本文在已知混凝土单轴受压应力-应变全曲线的几何特点基础上,给出了国内外五种混凝土单轴受压全曲线方程的分析及对比,阐述了相关曲线方程的适用性与优缺点。The stress-strain curves of concrete under axial pressure is the constitutive relation and especially important in nonlinear analysis for reinforced concrete. This paper based on well known geometric characteristics of the stress-strain curve gave comparative analysis on five kinds stress-strain curves of concrete under axial pressure and showed their applicability, advantages and disadvantages.
