This … The Sannai-Maruyama Overpass is a bridge for the Shinkansen Japanese bullet train that crosses the National Beltway No.7 through Aomori City at the northern tip of Honshu, Japan’s main island. Over the last decade, Extradosed bridges have become an attractive structural type around the world, due to the good results obtained with the first bridges constructed in Japan in 1994. 1993). It was only adopted six years later when the first extradosed bridge was built in Japan. This paper reviews some examples of extradosed bridges that were designed by the author, and highlights the differences between extradosed and cable-stayed bridges in terms of their structural aspects. The extradosed bridge can be defined as the structure being between the The extradosed bridge is a relatively new type of structure that has been developed since the 1990s. Die zweispurige Brücke führt den Seishō Bypass (E 84) der Ishibashi-Nebenstrecke der Nationalstraße 1 in 20 m Höhe über die Einfahrt zum Fischereihafen. jasbc.or.jp - Japan Bridge Association (in Japanese). Extradosed bridges are a new structural type of bridge that has been developed mainly in Japan during the last few years. The first such structure was the Odawara Blueway Bridge, designed and constructed in Japan (Shirono et al. Quelle: [1] Article von C. Burgoyne /Scantlebury aus The Structural Engineer- 6. After introducing the concept of extradosed bridges by J. Mathivat, this new type of bridge has been constructed in Japan. Matakina, a 11.30 m wide extradosed road bridge, incorporates a twin pylon, two planes of extradosed tendons and non-symmetrical spans of 89 and 109 m. During design, the pylon height, the capacity of the external tendons, the girder depth as well as cost efficiency were optimized. Good seismic quality was another important consideration. Japan etabliert hat. For corrosion protection the external tendons were grouted with an expanding light weight polymer grout. However, the idea was not totally accepted in its origin continent. Matakina Bridge, another extradosed bridge in Japan Crossing of the future Yanbaru Water Reservoir Near the town of Nago, the soon to be built Yanbaru Water Reservoir will be crossed by the Matakina Bridge at one of the reservoirs narrowest sections between the mountains. An extradosed bridge employs a structure that is frequently described as a cross between a girder bridge and a cable-stayed bridge. Since it becomes a unique type of structure for its advantages over other bridges. This bridge is used as a double-track railway bridge with 3 box section main girder which is stayed by diagonal cables in two planes, simply supported at the ends and rigidly connected with main towers. prestressed extradosed bridge was built in Japan: Odawara Blueway Bridge [6].

Kurzbericht ueber drei in Japan erbaute Schraegseilbruecken, bei denen der Haupttraeger in Spannbetonbauweise mit Kastenquerschnitt und innen liegender externer Vorspannung hergestellt wurde und durch durch eine Vielzahl von ebenfalls aus Spanngliedern bestehenden Schraegseilen ueber relativ niedrige Pylone abgespannt ist. Extradosed Bridges PhilippeVanBogaert*andHansDeBacker Bridges,RoadsandTunnelsResearchGroup,DepartmentofCivilEngineering,GhentUniversity,Ghent,Belgium The original concept of extradosed posttensioning in bridges is to obtain larger eccentricity of the tendons and thus to generate larger bending moments, opposing the effect of external loading.
