The steel bridge deck, as an important component of the bridge, has a huge impact on the safety and stability of the whole bridge. However, due to the special structure of the orthogonal anisotropic steel bridge deck, its stress behavior is different from that of the traditional steel bridge deck, and the demand for its stress analysis research is gradually highlighting.This paper takes the orthogonal anisotropic steel bridge deck as the research object, through the analysis and induction of its stress principle, constructs a stress model based on the axial force assumption, and compares and analyzes it with the actual engineering to verify the reliability of the model. At the same time, using modern numerical simulation technology, the strength, stiffness, and stability of the steel truss bridge orthogonal anisotropic steel bridge deck are calculated and analyzed by the finite element analysis method, and the stress performance is evaluated to provide scientific reference for the design of steel truss bridges.【Keywords】steel truss bridge; steel bridge deck; orthogonal anisotropic; stress analysis; strength; stiffness; stability.
