| 摘 要： | 通过对环形截面构件的研究，建立在复合受力务件下的统一破坏表达．首先建立截面的应力屈服方程；然后把截面应力用所施加的内力表达出来，代入屈服方程，得到环形截面构件在拉压、弯、剪、扭4种内力共同作用下破坏的统一表达式和相互作用曲线（面）．应用塑性力学、断裂力学和组合材料力学的成果，从理论的高度把钢筋混凝土构件破坏的形式统一起来，有较大的理论意义和实用价值．

| Abstract: | The unified equations and graphs on the general failure expression were presented through the study of reinforced concrete elements with annular section. The stress equations are established, then the stresses are expressed in the term of outer forces. Finally, the unified equations and graphs can be got out by inputting the stress expression into the stress equations. Using the result of plasticity mechanics, fracture mechanics and materials mechanics, the general failure expression on reinforced concrete members was put forward. |
