摘　　要：连续组合梁负弯矩区的侧向稳定可等效为弹性地基上的压杆稳定问题。为研究这一问题，分析了变轴力分布对压杆稳定解的影响，探讨采用变轴力弹性地基压杆稳定理论连续组合梁形变侧向失稳的实用设计方法。\ 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.
