Abstract
The paper considers peculiarities of analysis and operation of bridge decks with orthotropic deck plates of the roadway. As an example, the design of the superstructure of the existing driveway over the overpass of Dnieper Hydroelectric Power Plant dam with the left bank is considered. Defects and damages of load-bearing structures acquired during the operation of the carriageway are described. The non-uniform distribution of normal stresses in the orthotropic plate decking is investigated. Reduction coefficients characterizing the non-uniform distribution of normal stresses were found by analyzing the design model using engineering and analytical (normative) method and numerical method of calculation. The results of the numerical method are presented and analyzed in the form of vertical displacements and normal stresses in the orthotropic plate decking and shear stresses in the walls of the main girders. The results obtained are compared. Conclusions and recommendations based on the research results are formulated.
