Detail Design Development
Project period: 1997 – 1998
Client: Road Committee of Leningrad Region
Main parameters of the bridge:
– bridge length: 145.9 m span layout 25.8+3х28.1+25.8 m)
– bridge width: 15.38 m (9.5+2х2.25 m).
Design solutions: dismantling of the existing reinforced concrete decks as well as of the draw span steel decks, reconstruction of pier tops; construction of a composite continuous deck with cast-in-situ slab and flexible studs made of reinforcement steel, etc.
It was the first project in Russia where flexible studs made of ribbed bars were applied and welded on site by “Gefest” automatic machine. Connection of steel beams and reinforced concrete slab with flexible studs has been tested for durability. The tests have been carried out together with Bridge Research Institute in line with a jointly developed method. Another Stroyproekt’s partner for bridge testing was St. Petersburg State University of Architecture and Civil Engineering.
