Pavement stress analysis of orthotropic steel deck

Aiming at the common damage of steel bridge deck pavement, such as cracking, pushing and local packing and so on, the impacts of pavement on orthotropic steel deck such as maximum tensile stress, maximum shear stress and maximum deflection under the action of vertical and horizontal load were analyzed using finite element method, and the different mechanical results of pavement under the single-wheel load and under double-wheel load were compared. Analysis results show that the horizontal load has great effects on shear stress of pavement, especially longitudinal shear stress. When chosing the maximum tensile stress of pavement as design control index, the simulation results of single-type load are larger than those of double-type load. When chosing the maximum shear stress of bond coat as design control index, the simulation results of double-type load are larger than those of single-type load.
