Abstract

Abstract: The static behavior of diaphragms in hunging point and unhunging point respectively by mixed finite element mode l under 8-lane traffic load of the north channel bridge of Zhujiang Huangpu Bridge was studied; factors influencing the behavior of diaphragms such as stiffeners in both top and bottom plate and cable force were analyzed; reasonable hole position in diaphragm was proposed. After comparison of the stability of diaphragm with different stiffeners distribution, a reasonable and economical stiffeners setting scheme was presented to enhance the stability of diaphragm in unhunging point under vehicle loads.

Key words: flat steel box girder, diaphragm, finite element method, stress distribution, stiffeners setting

摘要： 以黄埔大桥北汊桥独塔双索面扁平钢箱梁斜拉桥为工程背景,采用索-梁-板壳混合单元建立梁段的三维有限元模型,分别分析了扁平钢箱梁吊点处和非吊点处横隔板在运营阶段8车道车辆荷载作用下的受力行为,得到横隔板应力分布的规律；通过分析顶底板加劲肋、索力对横隔板受力的影响,提出了较合理的开孔洞的位置。以非吊点处横隔板为例,分析了横隔板在各种加劲肋的布置下的稳定性,提出了较为合理经济的加劲肋布置方案,供大跨度斜拉桥钢箱梁设计参考。

关键词: 扁平钢箱梁, 横隔板, 有限元, 应力分布, 加劲肋布置
