In this paper, modeling strategy for member and section level is firstly established based on shear-flexible grillage theory cellular decks. In addition, modal analysis and static analysis under the dead and live load are conducted for composite simply supported and continuous box girder bridges, the alignment of which includes straight and curve. High accuracy and good applicability of beam-truss model of composite box-girder bridge can be verified due to good correlation of numerical results between elaborate and beam FE model. The research in this paper has laid the foundation for the further application of beam-truss models in the design analysis of actual composite box-girder bridge.
