Mechanical Characteristics of Orthotropic Steel Bridge Deck Pavement Based on ABAQUS
To analyze the mechanical characteristics of the orthotropic steel bridge deck pavement and determine the most unfavorable load position of the pavement,this paper established the stress model of the pavement by using the finite element software ABAQUS to analyze the mechanical characteristics of the pavement corresponding to different load positions under different types of wheel load.The results showed that the result of the double-wheel load was more conservative than that of the structural checking calculation.The most unfavorable load position for the displacement and maximum transverse tensile stress was at position No.3.With the increase of the distance to the transverse diaphragm,the vertical displacement and the transverse tensile stress increased gradually and reached the maximum at the distance of 2 m.
