    Abstract. The variants of modernization of steel-reinforced concrete bridge spans created on the basis of the existing span structure of multi-section closed contours are considered. Three variants for structural modernization schemes are presented, namely: the device of a reinforced concrete passage plate with a developed dimension in a traditional configuration, namely: the device of a reinforced concrete passage plate with a developed dimension in a traditional configuration, supported by plate consoles with girders on brackets; the device of a plate with developed consoles combined with parapets of fences, with cornices and girders bordering the consoles of the plate; the development of the plate to the required size by analogy with the second option, but supplemented by connections created in the plane of the struts, imposing restrictions due to their geometry on the freedom of mutual shear displacements. The results of the calculation are presented, which, based on a comparative analysis of the terms of the elastic forces potential, show the effectiveness of modernization of steel-reinforced concrete span structures of operated bridges. Moreover, the variant of transformation of the cross-section with its transformation into a three-section with the properties of a closed contour deserves the most attention.
    Keywords: steel-reinforced concrete span structures of bridges, multi-section closed contour, modernization of superstructures, terms of elastic forces potential, installation of reinforced concrete passage plate
