| 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...

| Abstract: | The static behavior of diaphragms in hunging point and unhunging point respectively by mixed finite element model 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 sett... |
