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. 相似文献

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. 相似文献

The St. Kilian Viaduct – competition of engineering and architectural layout, design, realization. The present paper describes the concept of design and the realization of the new viaduct called “St. Kilian” as part of the A 73 project near Suhl. The design is based on a filigree truss work structure as continuous composite beam with a longitudinal prestressed reinforced concrete slab. Slender pillows support this truss work. 相似文献

The Highway Bridge crossing the Werra Valley at Einhausen – new developments for the construction of a composite bridge with two separate superstructures Within the frame of the so called infrastructure projects “German Unification No. 16” the construction of the new highway A 71 in its section between the city of Meiningen and the border between Thuringia and Bavaria was planned and executed during the recent years. The most important and longest engineering project herein has been the new highway bridge crossing the Werra valley near the village of Einhausen being designed as advanced composite structure. With many new developments regarding fabrication, erection and protection against corrosion of the steel structure this bridge is marking a new milestone in modern bridge technology. 相似文献

Viaduct Elben – A steel‐composite bridge with one‐piece cross‐section. In the north of Siegen a non existing section of the German motorway Autobahn A 4 and of the federal highway B 54n, also called “Hüttentalstraße”, was completed during the last years. The 432 m long viaduct – called “Talbrücke Elben”, as an important element in the construction for the extension of the A 4, is in particular interesting because of its design and its construction itself. During the last years about 10 similar constructions have been implemented, others are currently planned. Therefore, it seems appropriate to report about the experiences with steel‐composite bridges in general and particular, always having the bridge “Talbrücke Elben” in mind. Furthermore, the paper intends to give an overview on further fields of application in the near future. 相似文献

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. 相似文献

The Pedestrian and Cycle Bridge Kehl – Strasbourg. The Rhine bridge between Kehl and Strasbourg is the new regional landmark and linking element of the International Gardening Show. The approach to unifying different functions and an architectural endeavour lead to a unique structural system. Two separate decks address the different situations on the river banks and, linked by a platform, form a balcony above the Rhine at midspan. The main bridge is a cable‐stayed structure with a steel pylon and a steel‐concrete composite deck. The approach bridges are continuous girders on steel columns. Both pile and flat foundations are featured in the design. The article describes the structural concept and design, outlines the erection procedure and discusses aspects of the dynamic behaviour of the bridge. 相似文献
