Extradosed bridges sind eine Zwischenstufe zwischen einer traditionellen Balkenbrücke und einer Schrägseilbrücke, bei der die Neigung der Schrägseile zwischen 0,4 > tan (alpha) > 0,2-0,25 liegt. Die Odawara Blueway Bridge (japanisch 小田原ブルーウェイブリッジ), in der europäischen Literatur oft einfach nur Odawara Bridge genannt, ist eine Straßenbrücke in der Stadt Odawara in der Präfektur Kanagawa in Japan.. 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. The concept of extradosed bridges has been taken up in Japan, where several bridges of this type have now been constructed. An extradosed bridge employs a structure that is frequently described as a cross between a girder bridge and a cable-stayed bridge. Himi Yume Bridge, Japan The Himi Yume Bridge is a 3-span continuous extradosed prestressed concrete girder bridge with a centre span of 180 m, located near the future Nagasaki Interchange of the Trans-Kyushu Expressway, Japan.

Introduction. Figure 1 shows the outline of the PC extradosed bridge. extradosed bridges emerged in the last two decades as a promising structural system to effectively and economically bridge spans ranging between 100 and 200 m. For such spans the prestressed box girder bridges require deep and heavy deck cross section. Shinkansen concrete bridges in Japan [1]. Good seismic quality was another important consideration. Regarding construction and load-bearing behaviour extradosed bridges represent a seamless transition between external prestressed concrete girder bridges and multispan cable-stayed bridges. What is an Extradosed bridge? The Extradosed Prestressed Bridge represents a relatively new bridge type. 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. The earliest bridge known to incorporate some of the features of an extradosed design is Bridge in Rzuchów near Leżajsk, constructed in Poland in 1980. The first such structure was the Odawara Blueway bridge, which was designed and constructed in Japan (Shirono et al., 1993). As an allusion to the famous cherry blossom period of the Nago region each spring, the sheathing of the tendons was colored in different graduations of pink. Extradosed-Eisenbahnbrücke Sapporo ist ein(e) Extradosed-Brücke, Eisenbahnbrücke und Spannbetonbrücke und wurde fertiggestellt im Jahre 1999. The first of this type bridge was constructed in Japan in 1994, and Japan has since built at least 29 examples of this bridge type. jasbc.or.jp - Japan Bridge Association (in Japanese). Next is the Ganter Bridge, constructed in Switzerland, designed by Christian Mennof Zurich, it preceded by several years the 1988 publication on the design philosophy of such bridges by Jacques Mathivat, who is credited with inventing the extradosed terminology and its design concepts. Die zweispurige Brücke führt den Seishō Bypass (E 84) der Ishibashi-Nebenstrecke der Nationalstraße 1 in 20 m Höhe über die Einfahrt zum Fischereihafen.

Schlaich, Mike / Apitz, Andreas / Duclos, Thierry / Kasuga, Akio / Romo Martín, José / Montens, Serge / Sankaralingam, Chithambaram / Sobrino, Juan (2019): Extradosed Bridges. The extradosed bridge is a relatively new type of structure that has been developed since the 1990s. From Wikimedia Commons, the free media repository. Keywords: Prestressed concrete bridge; extradosed bridge; cable stayed bridge, For the DYWIDAG Extradosed Tendons, external DYWIDAG Tendons type MC 19 and 27 Ø 15.2 mm with epoxy-coated strands were used. Mit der Canada Line Skytrain Bridge über den Fraser wurde 2008 die erste extradosed Bridge in Kanada erstellt. Als Extradosed-Brücke (extradosed bridge) wird eine vergleichsweise neue Konstruktion von Spannbetonbrücken bezeichnet, bei der die Spannglieder außerhalb des Querschnitts des Fahrbahnträgers über einen niedrigen Pylon geführt werden und dadurch das Tragverhalten einer Schrägseilbrücke und einer Balkenbrücke kombiniert wird. Der Brücketyp hat noch nicht einmal einen deutschen Namen (?). The Tsukuhara Bridge near Kobe, Japan, is the second bridge where the Japan Public Highway Corporation has used this technique. Extradosed bridges can be an elegant and economic solution for bridges with spans ranging between 100 and 250m. - List of bridges that received the Tanaka Prize "橋の写真館".

World Record for Extradosed Bridge with Extradosed Cables in Japan Sannohe-Boukyo Bridge. The Sannohe-Bokyo bridge is a three-span, extradosed prestressed concrete bridge with a total length of 400 m. It runs from east to west, connecting the Nanbu-cho, Sannohe-cho, and Takko-machi, Aomori Prefecture's agricultural development areas. The cable-stay angle with the deck is smaller compared to any cable-stayed bridge. It was only adopted six years later when the first extradosed bridge was built in Japan. It was originally planned as an arch bridge, but its design was changed because of the success of the Odawara Blueway Bridge, Japan's first extradosed bridge. 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.

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, which was designed and constructed in Japan (Shirono et al., 1993).The extradosed bridge can be defined as the structure being between the girder bridge and the cable-stayed bridge (Mermigas, 2008; Collings and Gonzalez, 2013). For corrosion protection the external tendons were grouted with an expanding light weight polymer grout. The concept of extradosed bridge goes back to 1988 with the proposal by the French Engineer Jacques Mathivat. Extradosed bridges can be an elegant and economic solution for bridges with spans ranging between 100 and 250m. 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. The first of this type bridge was constructed in Japan in 1994, and Japan has since built at least 29 examples of this bridge type. , between the Takatsuki and Kobe junctions on the subject regarding behavior of stay forces under load., out of 8 total with epoxy-coated strands were used 1988 with the deck is smaller compared any.
