摘要
本文根据势力驻值原理,求得单伸臂钢梁整体稳定临界弯矩的近似解,其值可用梁的有效长度表示。
The elastic stability of the single overhanging beams is investigated in the paper.The beams' neighbouring span is a single span and simply supported at the fulcrums,the beams' cross section is bi-symmetric.The solutions to the elastic lateral buckling problem of this kind of beams have been obtained by using the theorem of stationary potential energy.At last,the solutions are expressed by the way of effective length factors
