Rędziński Bridge in Wrocław—The Largest Concrete Cable-Stayed Bridge in Poland

Abstract

result of social protests against other alternative solutions. A large span bridge thus became necessary to allow for the unconstrained future modernization of Rę dzin water stage of fall and two water locks.The bridge consists of three substructures ( Fig. 2): -E1 southern fl yover: 610-m long, 11 span continuous beam (box girders) made of prestressed concrete, span lengths 40 + 2 × 52 + 56 + 6 × 60 + 50 m; -M2 cable-stayed main bridge: 612-m long, span lengths 50 + 2 × 256 + 50 m, with two separate superstructures made of prestressed concrete, suspended to a single 122-m high pylon;-E3 northern fl yover: 520-m long, nine span continuous beam (box girders), made of prestressed concrete, span lengths 50 + 7 × 60 + 50 m.The superstructure of the main bridge, presented in Fig. 3, consists of two box girders made of prestressed concrete class C50/60 (one for each carriageway of the motorway), suspended to an H-shaped concrete pylon (concrete class C50/60). Inclined side walls of the girders were made of reinforced concrete precast panels. AbstractThis paper describes the largest structure along the motorway ring road of Wrocław (Poland)-a cable-stayed bridge over the Odra River near Rę dzin barrage. The river flows there in its main bed, while inland navigation uses additional water channels. Pylon of the new bridge is situated on an island located between the river and the channels. The structure is 1742 m long and consists of two multi-span flyovers and a 612-m-long cable-stayed bridge with separate decks suspended to one 122-m-high pylon. The superstructure consists of two prestressed concrete box girders, one for each carriageway of the highway. The decks of the main bridge are suspended to a reinforced concrete pylon by 80 pairs of stay cables. The bridge with a deck area of approximately 65 000 m 2 was constructed within 36 months.

Validation of numerical models of concrete box bridges based on load test results

“…The main cable-stayed part of the Rędziński Bridge [6,15] consists of two parallel decks (Fig. 1) -east (E) and west (W) -connected with the central pylon by means of cable stays (Fig.…”

“…Access to the main bridge from the south is provided by two identical flyovers -one in each direction [5,6]. Each structure consists of 11 spans with the following lengths: 40 m + 2 Â 52 m + 56 m + 6 Â 60 m + 49 m, made of prestressed a r c h i v e s o f c i v i l a n d m e c h a n i c a l e n g i n e e r i n g x x x ( 2 0 1 5 ) x x x -x x x concrete C50/60.…”

Extradosed Bridges in Poland—Design and Construction

“…A comparison of the bridge in Kwidzyn with the largest Polish concrete cable-stayed bridge-the Rędziński Bridge in Wrocław (Biliszczuk et al, 2014) in terms of basic material consumption (concrete and prestressing steel) and unit costs is presented in Biliszczuk et al (2016). Obtained results indicate that a concrete extradosed structure with a span of about 200 m can be economical in comparison with a large-span concrete cable-stayed bridge.…”
