Abstract

This paper summarizes the stress characteristics of non-standard box girders and the grillage method, and according to the engineering practice experience, summarizes the characteristics of the grillage method in the stress analysis of non-standard box girders, and draws the corresponding conclusions. On this basis, the finite element models of the special-shaped bifurcated box girder and the widened box girder are established respectively. According to the analysis results and the operation of the bridge after completion, the grillage model can meet the needs of design checking calculation, provide theoretical basis for bridge construction, and it is worthy of reference for similar projects.
