Research on Shear Lag Effect of Curved Box Girder with Cantilever Plate Variable Width Section
In order to meet various terrains and special conditions, variable-width curved box girder bridges have been widely used in urban transportation road construction. In this study, the energy variational principle is used to establish the control differential equations and boundary conditions for the shear hysteresis effect of a box girder with cantilevered slabs with variable width curves, and the formula for the positive stresses in the cross section is derived by the difference method. Combined with examples, the analytical solution of this paper and the numerical solution of finite element under concentrated load and uniform load are in good agreement. In comparison with the equal cross-section curved box girder, the positive stresses in the cross-section of the cantilever plate widened curved box girder change by a greater magnitude and have a higher peak value.
