| 摘 要： | 玻璃纤维增强聚合物（GFRP）具有抗风化、抗腐蚀的性能，是钢筋的理想替代材料，且其重量仅为铪的1／5。桥面板自重的减轻，相当于提高了桥梁的承载能力。而对于GFRP桥面板的设计计算，目前尚无规范可循，设计中最关注的问题是受压翼缘的有效宽度和横向分布系数。为安全计，现阶段可不考虑GFRP桥面板与主梁的组合作用：横向分布系数可按杠杆法计算，但这两项都是偏于保守的建议，仅供参考。

| Abstract: | GFRP which has performance of resistance to weathering and corrosion resistance is a perfect substitute of steel bar. The weight of GFRP is just 1/5 of hafnium. The lightening of deadweight of bridge decks is equal to the advance of bearing capacity of bridges. As for the design calculations of GFRP bridge deck, there are no standards to follow currently. The problems deserving notice in design are transverse distribution coefficient and effective width of compression flange. For safety, the compounding function of GFRP ridge deck and spar boom can be leaved out of account at present, transverse distribution coefficient can be calculated according to lever method, but the two items of suggestion are conservative and just for reference. |
