| Abstract: | In the paper, the formulas of the total potential energy of the mono-overhanging beam are deduced from variational calculation, and the formula of the critical moment of the overall stability of the mono-overhanging beam is obtained. By introducing the equivalent calculated length coefficient of the overall stability and finding out the major influencing factors, the formula of is presented. |
