摘要
以上海泖港新桥(方案)-单索面宽幅钢箱斜拉桥为背景,对单索面宽幅钢箱梁在边斜腹板及锚索腹板间设置中腹板、不设中腹板、设置小纵梁三种构造参数情况,分析了活载作用下钢箱梁横向应力分布、箱梁空间扭转变形、纵桥向剪力滞效应等空间受力特性,提出了单索面宽幅斜拉桥钢箱梁横断面构造设计建议。
Taking the New Maogang Bridge(scheme)-a single-plane wide steel box cable-stayed bridge in Shanghai as the background for three structural parameters of setting up the middle web,not setting up the middle web and setting up the small longitudinal beam between the edge inclined web and anchor cable web of the single-plane wide steel box girder,the article analyzes the spatial mechanical properties of the transverse stress distribution,spatial torsional deflection and longitudinal shear flag effect of steel box girder under the live load,and puts forward the proposal for the transverse section structure design of the wide steel box girder of single-plane cable-stayed bridge.
