Research on Shear Lag Effect of Wide Continuous Composite Steel Box Girder
Taking the approach bridge on the north side of the main bridge of Wangsheren Interchange Access Project from G220 to the Jinan-Qingdao Expressway as the background,the finite element software ABAQUS 6.14 is used to establish the spatial shell model of the composite steel box girder,the distribution law of the shear lag effect under the uniform force and concentrated force is analyzed,and the calculation results are compared with those of the steel box girder and the calculation method specified in the specification.Some suggestions on the design of wide-width composite steel box girder are put forward.
