摘　　要：对于组合梁正弯矩区段,主要发生腹板局部屈曲;对于负弯矩区段,不但可能发生受压翼缘的侧向失稳,而且也可能发生腹板的局部屈曲。本文综合汇集了组合梁稳定分析的多种文献,对上述两种情况下的稳定分析进行了较全面的论述和比较,对现行规范中有关连续组合梁稳定分析的理论概念和计算方法的深入理解具有一定的指导意义。The webs of composite beams are likely to have local buckling in the region of positive bending moments.Meanwhile,not only the webs are likely to have local buckling,but also the compressed flanges are likely to have lateral buckling in the region of negative bending moments.In this paper,many articles concerning with stabilities of composite beams have been compiled together,put forward and compared with,which are certainly helpful to get engineers better understanding the theories and methods of stabilities of composite beams.
