摘　　要：以锈蚀钢筋混凝土梁非线性微分方程为依据,通过求解微分方程,给出了梁端弯矩作用下锈蚀钢筋混凝土梁截面协同工作系数的理论表达式.通过该表达式,讨论了不同梁端弯矩比对截面协同工作系数的影响,给出了一些有益的结论.According to the nonlinear differential equation of corroded reinforced concrete beam, the expression is given by the coordination coefficient of the corroded reinforced concrete beam which is under the end moment. Through the expression, the influence factor of coordination coefficient under different end moment ratios is discussed,and some useful conclusions are also drawn.
