组合梁在框架中的应用

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.
