Abstract

In view of the particularity that the current analytical theory of box girder distortion is mainly limited to single-cell cross-sections and double-cell cross-sections without cantilever plates, this paper uses the plate element method to establish the distortion control differential equations of single-box and double-cell box girder with cantilever plates, and gives corresponding cross-section geometric parameter calculation formula. The initial parameter method is used to solve the distortion control differential equation, and the analytical solutions of the distortion double moments and distortion angles of a simply supported single-box and double-cell box girder are given. Numerical examples of simply supported box beams show that the analytical solution of distortion warping stress is in good agreement with the ANSYS finite element numerical solution; the concentrated load in the lane load has the greatest impact on the distortion warping stress of the control section, and the mid-span section characteristic points caused by the concentrated load The warping stress at the mid-span cross-section characteristic point of the double-cell box girder is reduced by 11.47% compared with the corresponding single-cell box girder.
