Abstract. The features of the calculation, design and construction of prestressed bridge crossings are considered using the example of an educational center in Kogalym, designed to train specialists in the fuel and energy industry. When designing the facility, the design engineers of Kazan Giproniiaviaprom named after B. I. Tikhomirov used extraordinary, complex technical solutions that proved their reliability after a year of operation. Among them: suspended reinforced concrete floors, prestressed bridge crossings, large-span translucent arch-type structures, lattice roof beams and much more. Bridge crossing structures connect opposite sides of the "streets" inside the building at an angle of plan, which significantly lengthens the spans and increases internal forces both in the superstructure itself and in the supporting elements of the supporting frame. Prestressing made it possible to organize large spans and significantly reduce the weight of building structures, make them as elegant as possible, and also save steel and concrete. The successful operational experience of the proposed design solutions allows them to be applied to similar buildings and structures.
