| Abstract: | \ Lateral buckling of continuous composite beams in hogging bending can ge delt with as the buckling of columns with continuously elastically lateral supports, in the paper, comment and analysis are given for the effects of axis force distribution on the buckling solution. Effort is made to develop a practical method for the design of lateral buckling of continuous composite beams by using the theory of columns with elastcally lateral restraints under a varying axis force distribution. |
