| 摘 要： | 将纵横弯曲的梁柱在原基准坐标系中的大变形问题转换到某一局部坐标系中，近似以小变形问题处理，建立起一组“三弯矩方程”组，使问题求解。通过算例，验证了本方法的正确性。

| Abstract: | The large deformation problem of a continuous beam-column in a global coordi-nate is transformed into one certain local coordinate which is then treated approximatelly as asmall deformation problem. And a system of equations of three momentsis developed forsolving this kind of problems.The correctness of this method is verified by examples. |
