Die MaChang‐Brücke in Südkorea – Schrägkabelbrücke mit Verbundüberbau für Straßenverkehr

The MaChang Bridge in South Korea – Stay‐cable bridge with steel composite deck for highway traffic. The MaChang bridge is part of the new 4 lane highway connecting the cities of Masan and Changwon crossing over the Masan Bay. This high level crossing has a total length of 1,700 m and is composed of a 550 m long East viaduct, the 740 m long mainbridge and a 410 m long West viaduct. The mainbridge is the dominating structure of this link and consists of a two tower cable‐stayed bridge with a mainspan of 400 m and 170 m side spans. It provides clearance for the 350 m · 64m navigational channel and allows the passage of vessels up to 80.000 dwt.     

Die zweite Geo‐Geum‐Brücke in Südkorea – Schrägkabelbrücke und Vorlandbrücke für Straßenverkehr mit Verbundfachwerkträger

The 2nd Geo Geum Grand Bridge in Korea – cable‐stayed bridge and approach bridge with composite truss girder for roadway traffic. The 2nd Geo Geum Grand Bridge forms part of the fixed connection from the mainland to the Island of Geo Geum in South Korea (Fig. 1). This high level crossing is composed of a 912 m long approach viaduct and a 1116 m long stay cable bridge with a main span of 480 m. The approach viaduct is a continuous girder with regular spans of 120 m. The superstructure of both bridges is a composite truss girder bridge, which carries a 2 lane highway on top and a pedestrian and bicycle way on the lower deck. The main design considerations were function as a high‐way, innovation in design and visual harmony with its surround‐ings. The stay cables are arranged in a single plane at the centre of the bridge, their semi‐fan arrangement with bundled configur‐ation gives a very special and unique appearance.     

Schrägseilbrücke für Straßenbahn‐, Geh‐ und Radverkehr

Cable‐stayed bridge for tramway, pedestrians, and bike traffic. For the development of the new quarter “Parkstadt Schwabing” in den North of Munich, the transport connection is established by a new tramway, the line 23. Thereby, a new bridge construction became necessary for the crossing of the main circular roadway “Mittlerer Ring” at the Schenkendorfstraße. The extraordinary bridge structure in direct conjunction with the glass enclosure of the Petuel‐tunnel belongs to the most spectacular metropolitan crossing locations of Munich.     

Die neue Berliner Brücke in Halle – Erste deutsche Schrägseilbrücke in Verbundbauweise

The new Berliner Brücke in the city of Halle (Saale) – First German cable stayed bridge in composite construction. The new Berliner Brücke in the middle of the Händel ‐city of Halle (Saale) is a cable stayed bridge with a central pylon and a stiffening truss in composite construction. The stiffening truss with the outline of the deck is bent and the pylon is skew to the bridge centre line. The bridge is exposed to stress out of the working load, e.g. traffic loads, heavy traffic loads and tram loads. The bridge crosses partly electrified tracks of the DB AG facilities in the north of the main station. Innovations and optimisation of building costs are a product of the difficult conditions to satisfy the urban development demands.     

Die zweite Strelasundquerung – Statik,Konstruktion und Montage der Verbund‐ und Schrägseilbrücke

The second Stelasund crossty – Structural design and erction of the composite and cable‐stayed bridge. Together with the construction of the new Baltic autobahn A 20 Lübeck – Stettin the Rügen feeder “B 96 n Stralsund/Rügen”, approx 55 km long, between the A 20 in the region of Grimmen and the town of Bergen on Rügen is also being realised. With the construction of the new “B 96 n Stralsund/Rügen” Rügen feeder an effective transport link between the largest German island, Rügen, and the German and European long‐distance road network is being implemented. An essential component of the whole building project is the second Strelasund crossing between the town of Stralsund and the island of Rügen. The main structure of the 2.8 km long bridge design is configured as a stayed cable bridge.     

Die Elbebrücke Niederwartha – die erste Schrägseilbrücke in Sachsen

The Elbebridge Niederwartha ‐ the first cable‐stayed bridge in Saxonia. The following article describes the preliminary studies and the design of the new roadwaybridge across the river Elbe near Dresden. The new bridge will have a total length of 367 m and a main span of 192 m. It will be come the longest main span and the first cable‐stayed bridge in Saxonia.     

Neubau einer ÖPNV‐Brücke für Straßenbahn,Radfahrer und Fußgänger zum Kienlesberg in Ulm

New ÖPNV‐Bridge construction for tram, cyclistes and pedes trians ”Kienlesberg“ in Ulm. The core‐part of the construction of the tram line number 2 in the city of Ulm is an engineering structure, which is designed as a combined tram‐ and road‐bridge and leads the traffic as an extremely slim, semi‐integral steel bridge over a high‐frequency inner‐city railway terrain. The bridge design was awarded after a realization‐competition and selected for execution. The superstructure cross‐section is divided into two parts. The separation between the pedestrian and bicycle travel area and the roadway is carried out by a main girder which is partly designed as a plate girder and partly as a truss girder. The design of this beam is adapted to the flow of the moments and creates a particular charisma of the structure. The monolithic connection of the steel deck with the supporting steel columns and the conventional bearings in the area of the abutments is generating the statically relevant semi‐integral superstructure. The special urban erection situation with the use of: – a temporary assembly platform – the approx. 15 m high columns of the final structure – a temporary launching nose and the elimination of a large number of auxiliary supports creates interesting statically structural conditions. It was possible to assemble the structure in an extremely short construction period, and to limit the influence on the railway traffic under the assembly area.     

VFT‐WIB‐Brücke bei Vigaun – Verbundbrücke mit externer Bewehrung

VFT‐WIB viaduct in Vigaun – a composite bridge with external reinforcement. With the introduction of the composite dowel the possibility is given to develop new construction methods for bridges. The VFT‐WIB construction method is used for the first time for the road bridge in Vigaun/Austria, which is in service since autumn 2008. The cross‐section is composed out of two prefabricated elements with halved rolled girders, working as bottom flange. The composite dowels are manufactured by cutting the rolled girder into two halves with a special cutting‐line. These halved girders work as external reinforcement, which leads to very slender and economical composite structures. Below details about the planning process, the design and the construction process of 78m long three span framing bridge over the railway line from Salzburg to Wörgl are shown.     

Die Brücke Lockwitztal – eine Revision nach Entwurf und Ausführung

The Bridge Lockwitztal, a Review of Design and Execution. In the course of the newly built federal motorway A 17, the bridge Lockwitztal crosses a wide valley in a maximum height of 64 m, with a length of 723 m. At the bottom of the valley lies a suburb of Dresden and at the valley slopes exist nature areas which have to be conserved. With the executed design, an adequate solution for the demanding situation was found. The two main spans are each 125 m. In four of the spans are situated concrete arch struts, which together with the composite superstructure and the piers form an integral frame system. The bridge shows a new way of deploying the aesthetic value of arch systems in the crossing of valleys up to now thought as not suitable for this and with the innovative construction was developed a novel link between arch systems and strutted frame systems. In the paper are discussed the essential elements of the construction and of the building processes in review after execution.     

Bewegliche Brücken für den Straßenverkehr in Deutschland

Movable bridges for road traffic in Germany. In Germany there are about 120000 fixed bridges for road traffic, on the other hand there are only 130 movable bridges for road traffic in practical application. In the following paper this bridge category is presented with partly very interested technical solutions. Flap bridges with scale beam, flap bridges with deep‐seated counterbalance, lifted bridges and swing‐bridges are treated. Some notable, built bridges are presented for every category. Finally special technical dates from nearly all built bridges are summarized in tables, which give a survey for the respective movable bridges in Germany.
