本文以国内在建的主跨最大的波形钢腹板预应力组合连续箱梁桥———河南桃花峪黄河大桥跨大堤桥为背景,对该种新型钢-混组合结构桥梁的剪力滞效应进行分析。重点研究了不同荷载组合工况下典型截面的剪力滞效应,研究成果可为波形钢腹板预应力组合箱梁桥的设计提供参考。
In this paper, under the background of the domestically-built prestressed continuous box girder bridge with the largest span of corrugated steel web-Henan Peach Valley Yellow River Bridge across the embankment bridge, the shear lag effect of the new type of steel-concrete composite bridge Analyze. The shear lag effect of the typical section under different load combinations is mainly studied. The research results can provide reference for the design of corrugated steel web prestressed composite box girder bridge.
