摘　　要：钢-混凝土组合梁是一种优秀的结构形式,连续组合梁是常见的组合结构,它的负弯矩区段可能产生侧向失稳,从而降低承载力。文章通过计算分析,发现可以用支座负弯矩调幅和减小梁间距的办法,满足侧向稳定的要求。Steel-concrete composite beam is a kind of excellent configuration, consecutive composite beams is acommon composite structure, its beating capacity will be reduction when its negative bending regions genesis lateral buckling. This paper can satisfy the requirement with steady lateral buckling with the method that scales down the bending moment and abate the space between beams.

关 键 词：连续组合梁 侧向屈曲 承载力 弯矩调幅 梁间距
