| 摘 要： | 基于刚度下降提出了一种混凝土损伤指标，可直接表示为应变的函数．建立了截面弯矩与截面变形及损伤与截面变形之间联系的一般公式，对简支梁在不同配筋和加载情况下进行全过程损伤分析，说明了本方法的可行性及其与实际现象的一致性．

| Abstract: | A damage index of concrete based on the decline of stiffness is established ,which can be directly expressed with strain. The general relations between the bending moment and deformation of the beam cross-section, and those between the damage and deformation of the beam cross-section are set up. This method is found feasible and close to reality by analyzing the whole damage process of simply supported reinforced concrete beams, which have different reinforcement ratios and loads. |
