| 摘 要： | 狭长矩形梁的侧向屈曲是工程设计中要考虑的重要问题 ,文中讨论了两种狭长矩形截面简支梁在一端受集中力偶作用时发生侧向屈曲的问题。从理论上推导了其临界载荷计算公式 ,同时给出了用能量法计算其临界屈曲载荷的表达式 ,并给出了其近似解 ,两者结果吻合很好。该公式可供工程设计人员使用。

| Abstract: | The lateral buckling of two kinds of pin ended beam under the action of a couple at one end of the beam is discussed. The critical value formulae of lateral buckling are derived by using theory analysis and energy approximate methods. The results obtained by the two methods are in good agreement. The formulas can be applied in the design of engineering structures. |
