The South Bridge, Kyiv, Ukraine

The new South Bridge over the Dnipro River in Kyiv, Ukraine, consists of a 564.5 m long cable-stayed portion with a main span of 271 m, and a concrete approach viaduct with a total length of 662 m. The bridge carries a six lane roadway, two rail tracks and four large-diameter water pipes. The total live load is about 246 kN/m. Stiffening girders on the main span side of the pylon are continuous three-span steel box girders, while on the opposite side the girders are segmental prestressed concrete box sections. The pylon is of reinforced concrete construction. Several solutions for the pylon-girder junction were studied. Eccentric hinged connections between the bottom flanges of the stiffening girders and the pylon were chosen. The aerodynamic stability of the bridge and its principal elements was investigated by calculations and wind tunnel testing. Stress distribution in connections was verified on models.
