Modeling the general solid web continuous box girder and opening - in - web ( open web ) continuous box girder by ansys finite element modeling tool, node stress of governing section and corresponding shear lag values are analyzed. the solution is validated by comparing with variational results and modeling test values. based on the model, the section shear lag induced by dead load, prestress tendons and car loads under the most unfavorable condition and lateral symmetry are also approached. the influence of shear lag effect in double - level continuous box girder is considered with opening - in - web and the web location. the analysis indicates that double - level - load arouses less shear lag effect than one - level - load. when self - weight and prestressed tendons act on together, the shear lag effect on box girder take on a evidently change
基於所建立的有限元模型，本文分別對實腹和腹板開孔兩種箱梁在恆載、車載、預應力荷載作用時，各主要截面的剪力滯效應進行分析，通過施加縱向最不利的和橫向對稱的車輛荷載，研究實腹連續箱梁和空腹連續箱梁在承受雙層荷載和單層荷載時引起的剪力滯效應，並考慮腹板開孔及開孔位置對于連續箱梁剪力滯效應的影響。分析表明，雙層車載對于箱梁引起的剪力滯系數比單層車載的影響要小，對于箱梁中存在引起的剪力滯后現象有一定的改善作用。 -
