Client: Novosibirsk City Administration, Road Construction Agency
Bugrinsky Bridge is the third bridge across the Russia’s largest river Ob in Novosibirsk. The bridge is part of South-West transit highway, which links the M-51 Baikal and M-52 Chuisky Trakt motorways.
The network arch of the bridge resembles the city’s coat of arms, which features an arch bridge and a red bow.
An unconventional launching procedure on a vertical circular curve was chosen for erection of the arch, which required minimum of auxiliary steel structures and enabled the shortest construction time.
In 2016, the project received a FIDIC Award of Merit for demonstrating innovation, quality, professional excellence, principles of transparency and integrity, sustainability and respect for the environment.
Bridge length — 2091 m
Width — 34,5 m
Arch height — 70 m
Central span length — 380 m
Span layout, m: (62,5+2×78+74,4)+380+(77,5+2×78+74,5)+(59,5+4×66+59,5)+(74,5+105+74,7)+2×(41,5+2×42+41,5)+(41,5+42+41,5)]
Lanes — 6
The engineering and design effort resulted in a solution with a 380-m long network arch that is unique in terms of its dimensions and erection method. In Russia, the largest similar arches with flexible suspenders were 160 m long as a maximum.
The river span of the bridge is a combined arch deck with inclined crisscross suspenders (so called network arch): the arch is 70 m high and the arch legs are inclined inwards by about 12o towards the longitudinal axis of the deck.
The designers managed to find a solution that met the following criteria:
Reduced steel consumption for the arch and the bottom flange due to decreased bending moments;
Reduced effect of live loads on cables tension;
Reduced material consumption for cables due to their optimised cross-sections;
Reduced maximum forces in cables and their cross-sections;
Decreased stress variation amplitude and reduced risk of fatigue failure;
Aesthetically pleasing bridge appearance
The designers managed to find the best solution for the cable system arrangement, which allowed achieving an extremely efficient design of the deck system enabling reduced steel consumption and ensuring a high rigidity of the structure.
Based on the proposed engineering solution, the architects developed an aesthetic concept of the bridge. Despite the considerable dimensions of the deck, the arch span is a light and visually pleasing structure. Moreover, the arch looks like a hunting bow which has a symbolic meaning in relation to the Siberian history.
Bugrinsky Bridge Project receives FIDIC Award of Merit
26 September, FIDIC Awards 2016 for outstanding engineering projects were presented in Marrakesh, Morocco. Stroyproekt received an Award of Merit for the Bugrinsky Bridge Project.
Bugrinsky Bridge over the Ob River in the City of Novosibirsk Short-Listed for the FIDIC Awards
According to the Secretariat of International Federation of Consulting Engineers (FIDIC), the Bugrinsky Bridge project submitted by Stroyproekt to the FIDIC awards in the category “Outstanding Projects of the Year 2016” has been short-listed.
The Bugrinsky Bridge Project receives another award from the industry
The design of Bugrinsky Bridge in Novosibirsk developed by Stroyproekt won the industry professional competition organised by NOPRIZ, National Association of Researchers and Designers.
Stroyproekt participates in All Russia Exhibition “Road Construction Achievements and Innovations” in Novosibirsk
Maxim Sokolov, Russian Minister of Transport, opened the Exhibition. The opening ceremony was also attended by Igor Levitin, aid of the Russian President, Roman Starovoit, Rosavtodor Director, Vladimir Gorodetsky, Governor of Novosibirsk Region, and Anatoly Lokot, Mayor of Novosibirsk.
Arch span of Bugrinsky Bridge in Novosibirsk is about to be completed
The Contractor has almost completed the installation of steel covering elements in the arch span. These decorative elements with the total weight of over 300 tons hide the arch connection to the bridge floor.
