| 摘 要： | 本文采用Ｒａｙｌｅｉｇｈ－Ｒｉｔｚ法求解两端不等弯矩作用下单轴对称开口薄壁截面梁柱弯扭屈曲临界荷载，分析中考虑了三种常见的边界条件以及屈曲前变形的影响，将本文弯扭屈由临界荷载理论值与试验值比较，吻合较好。

| Abstract: | The Rayleigh-Ritz method is used to determine the torsional-flexural buckling load of singly symmetric thin-walled open sections under axial thrust and unequal terminal moments. Three kinds of common boundary conditions are taken into consideration, and the effect of Pre-buckling deflections is included in the analysis. The theoretical torsional-flexural buckling are in satisfactory agreemint with the values obtained experimently. |
