钢管混凝土本构关系的数值计算，在MATLAB环境直接运行，可得到应力—应变曲线。-Numerical calculation of the steel pipe concrete constitutive run directly in MATLAB environment, the stress- strain curve can be obtained.

利用该程序可以将钢管混凝土的本构关系与实际工况相结合，进行精确计算(By using this program, the constitutive relation of concrete filled steel tube can be combined with the actual working condition, and the accurate calculation can be carried out)
