WebNov 7, 2016 · The elastic stability of two span continuous beams has been studied using FEA methods. Two formulae for estimating the critical loads are proposed, one is suitable for two-span beams with one span loaded, while the other is suitable for two-span beams with both spans equally loaded. Webanalysis of continuous beams and frames; for con tinuous beams, the method is identical with the older moment distribution method. The relaxation method can be applied analogic? fly to other physi cal problems (electrical networks, elastic stability, stiffened suspension bridges, etc.). The foregoing methods are good for any frame system.
