摘　　要：钢筋砼的非线性分析对于研究结构的破坏及延性是十分重要的．由于非线性计算本身具有与线性计算不同的特点，因而会碰到一些意想不到的情况．本文以钢筋混凝土对称配筋截面为例，说明了在其弯矩与曲率的非线性计算过程中可能会遇到的问题，并对它们进行了剖析．For the damage and ductility of reinforced concrete, it is apparent that nonlinear analysis is of great importance. Because of its particular features which are different from the linear analysis, there are many cases we would encounter during the nonlinear analysis procedure. This article takes example of symmetry distributed bars of a rectangular section to show what may be encountered in the nonlinear moment-curvature analysis. Some comments are given as conclusions.
