摘要 讨论了工字型简支梁在一端受集中力偶作用时的侧向屈曲问题,从理论上推导了其侧向屈曲的临界载荷,并同时用能量法给出了近似计算公式。 The lateral buckling of S shape pin ended beam under a couple applied at one end is discussed. The critical value formula of lateral buckling is derived by using two methods-theory analysis and energy approximate methods, and the two methods give the same results. The formula can be used in design of mechanical equipment and engineering structure.
