摘要
本文用李兹法导得了梁柱弹性弯扭屈曲临界条件的一般方程,并且将其临界荷载用临界弯矩表达,而不用临界压力表达,这是与传统的方法有所不同的。利用这个表达式,来研究梁柱的弹性弯扭屈曲更直接、更简单。而且某些问题用其他方法来求解,很困难时,采用本文方法来求解,则很容易。这就是这种方法更为有用之处。
In this paper, the general equation of critical conditions of elastic torsional-fl exural buckling of beam-columns is obtained by Rayleigh-Ritz method but the expression of critical load is obtained by critical moment rather than critical compression force which is different from the traditional way.Making use of this expression to stady elastic torsional-flexural buckling of beam-columns can be more direct and simpler. And it is more useful because some problems, Which are difficult to be solved by other method, can ba solved easily by this method.
