摘　　要：由于我国钢材产量与质量的提高,混凝土桥梁的造价相对提高,钢桥在我国有了更为广阔的发展前景.为使钢桥结构的设计更加适用、安全、经济、美观、耐久,对中小跨径公路钢桥合理构造和标准化的研究具有实际意义.本文分析计算了组合结构单梁最优造价,并给出不同跨径、主梁间距下推荐的主梁截面和主梁布置方案.As the increasing of steel output,cost of concrete bridges are relatively increased.Steel bridge in China has a broader prospect for development.Research on reasonable structure and standardization of medium and small span highway steel bridges to improve steel bridge’s safety,economy,beauty and durability has practical implications.In this paper,the optimal cost of single beam with composite structure was analyzed and calculated,and the recommended section of main beam under different span and spacing were given.
