Abstract In this paper, the results of the numerical parametric study are presented, in which the M‐V interaction behaviour of box‐girder bridge deck specimens was investigated. For this study, an advanced numerical model was used, previously calibrated against the experimental results. Based on the numerical results and the existent rules for the trapezoidal box‐girders, new design models were proposed for the prediction of the bending and shear resistance of cross‐sections with the curved bottom flange. Additionally, the force‐based M‐V interaction equation proposed by Jáger et al. [1] that is also adopted in the new version of EN 1993‐1‐5 [2] is verified and slightly modified to fit for this type of the cross‐section.
