摘　　要：针对钢—混凝土组合梁在框架结构应用中的缺陷,提出了在负弯矩区增设盖板的组合梁改进方案,经计算其承载能力,指出加设盖板后,翼缘的宽厚比能满足要求。According to the defects in the application of the steel-concrete composite beam in the framework structure,the paper points out the improvement scheme for the composite beam by adding cover plates at the negative moment areas,and points out the width-to-thickness ratio of flanges can meet the demands after the addition of the cover plates.

关 键 词：组合梁 负弯矩区 反弯点 盖板
