    Abstract. One of the prospect areas in bridge construction is the use of aluminum alloys, which have a number of technological and operational advantages over traditional steel and reinforced concrete structures. The possibility of forming aluminum alloys is used to create open and closed profiles of complex shape, which in combination with welding technologies makes it possible to obtain orthotropic plates with high strength and rigidity. The work and the stress-strain state of orthotropic plates made of a certain aluminum alloy are considered. The plates consist of ordinary and end sections obtained by extrusion and connected by friction stir welding. The main area of application of orthotropic slabs is the decking of pedestrian and road bridge structures. As part of the study of the work of orthotropic plates, the physical and mechanical properties of this alloy were determined on samples made by extrusion methods, as well as the properties of samples of welded joints of friction stir welding. Under loading, displacements and relative deformations were controlled. For the selected scheme, a more detailed finite element modeling was carried out in the software package. The reliability of finite element modeling was confirmed by comparing their results with the stress-strain state determined experimentally. Based on the results of numerical modeling, the stress-strain state of the orthotropic plate structure was evaluated, with the construction of deformation plots along the maximum loaded cross-section.
    Keywords: orthotropic deck, aluminum alloy, static tests, stress-strain state, finite element modeling, friction stir welding
