What unites the bridge over the Golden Horn Bay and the new stadium in St. Petersburg?

The cable-stayed bridge across the Golden Horn Bay in Vladivostok became one of the first examples of domestic bridge construction over the sea straits, and one of the first cable-stayed bridges in the country, covering a distance of more than two kilometers. The cable-stayed structure with a central span of 737 meters is supported by V-shaped pylons with a height of 225 meters, the balance of which is achieved due to the eccentric attachment of the cables relative to their axis. In order to take into account possible seismic and wind impacts, additional research was carried out during the design process and advanced engineering solutions were applied. At the 100+ Forum Russia, the unique design experience will be discussed in a report by Roman Guzeev, Head of the calculation department at the Institute of Giprostroymost St. Petersburg.

Dmitry Derevyankin, Head of the Bridge Calculation Department at the Giprostroymost Institute St. Petersburg, will talk about the design of a cable-stayed bridge across the Petrovsky Fairway in St. Petersburg. This is one of two cable–stayed bridges located on the Central section of the Western High-Speed Diameter highway, which connects the northern, central and southern parts of the city in the shortest way. Bridge diagram - 60+110+240+110+60 M. A 50 m wide steel-reinforced concrete superstructure is suspended from two 123.92 m high pylons along the axis of the bridge using three planes of shrouds. Despite the relatively short length of the central span, the bridge design has a number of features: the large width of the superstructure, the need to regulate forces in the longitudinal and transverse directions, the unusual shape of the cable-stayed fan, the need for detailed consideration of the order of inclusion in the work of the reinforced concrete slab superstructure, etc. These factors make the bridge a remarkable example of the domestic practice of designing and calculating cable-stayed bridges.

Dmitry Maslov, Chief Project Engineer at the Giprostroymost Institute Saint Petersburg, will present a report on the problems of calculating the cable-stayed structure of a new football stadium in Saint Petersburg. This is a roof in the form of a shallow dome supported by a system of shrouds with inclined pylons, along which a sliding structure will move. The combination of a non-standard building structure and a mechanism gave rise to a set of design problems that were not so easy to solve with the help of standard functionality and available finite element software. The report provides a statement and description of the solution of such tasks as selecting the optimal distribution of forces in the shrouds, determining the sequence of tension of the shrouds, taking into account the limitations on the bearing capacity of structural elements at the installation stages, as well as the task of calculating the passage of the sliding roof over the stationary part of the coating.

The reports of specialists from the Giprostroymost Saint Petersburg Institute will be presented as part of the thematic section "Modeling extreme impacts on large Span bridge structures. Engineering solutions". For more information, see The 100+ Forum Russia 2016 program
