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.     

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 Elbebrücke Blaues Wunder in Dresden – Tragwerk und Maßnahmen zur weiteren sicheren Nutzung

The Elbe bridge “Blue Wonder” in Dresden – Structure and measures for further safe use. The bridge “Blue Wonder” across the river Elbe in Dresden will have been 111 years in this year and should stay in use as a symbol of Dresden so long as possible. The following publication describes after an introduction about the bridge system with numerous specials particularly the questions of static calculation, assessment of remaining fatigue life and further safety use of the steel construction and the anchor chambers.     

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.     

Zur maßgebenden Verkehrslaststellung bei Schrägseilbrücken

Appropriate traffic load cases for steel and composite cable – stayed bridges. A significant problem in the global analysis of bridge structures is to find the most unfavourable position of the traffic loads for each cross‐section. In practice usually those traffic load cases are chosen which maximise one part of stresses at the cross‐section (often expressed in form of internal forces). First of all a simple method is presented to find out the most unfavourable traffic load position, also applicable for complex interaction formulae including web buckling. Secondly an example of a cable‐stayed bridge is analysed. For two significant sections of the bridge deck the results are presented. The stresses due to the conventional practical procedure are compared with the more accurate ones. The behaviour is explained by the corresponding influence lines. Based on these results some proposals for practical work are given. The presented procedure is also applicable to other types of construction works and materials (e.g. reinforced concrete).     

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.     

Die Bahretalbrücke – eine Verbundbrücke mit Vollfertigteilen

Der Einsatz von Vollfertigteilen im Stahlverbundbrückenbau hat bisher in Deutschland wenig Anwendung gefunden. Im internationalen Großbrückenbau, insbesondere auch beim Bau von Schrägseilbrücken, ist die Herstellung der Fahrbahnplatte von Stahlverbundbrücken mit Vollfertigteilen eine häufig ausgeführte Variante. Am Beispiel der Bahretalbrücke im Zuge der Staatsstraße S 107n sollen die Vorteile dieser Bauweise beschrieben und einige Hinweise zur konstruktiven Ausbildung dargestellt werden. Application of prefabricated sections for composite bridges shown on the example of Bahretal Bridge. The application of the prefabricated sections in composite constructions has not been often used in Germany. In the international bridge building especially in building of cable stayed bridges prefabricated sections in the assembly of the deck are often used. The advantages of using this method and some details of the construction will be shown on the example of the Bahretal Bridge.
