基于Ｋｏｉｔｅｒ理论，提出了一个分析变截面连续梁初始后屈曲的方法。它的主要原理是借助传递矩阵的概念，首先导出连续梁在临界状态下首跨右端（或末跨左端）的刚度系数算式，然后进一步考虑后屈曲时该系数由于超临界变形所引起的变化，从而可将连续梁的初始后屈问题化为带弹性支承的单根粱处理。实例表明了这一方法的有效性． Based on the theory of Koiter, a method of analyzing the initial post-buckling of a variable cross-section continuous beam is proposed. Its main principle is to use the concept of transfer matrix to first derive the stiffness coefficient of the continuous beam at the right end of the first span (or the left end of the span) in the critical state, and then further consider the change of the coefficient due to the supercritical deformation in post- Thus, the problem of initial flexion of continuous beams can be transformed into single beam processing with elastic support. The example shows the effectiveness of this method.
