The concept of extradosed bridges has been taken up in Japan, where several bridges of this type have now been constructed. jasbc.or.jp - Japan Bridge Association (in Japanese). 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.. 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 Tsukuhara Bridge near Kobe, Japan, is the second bridge where the Japan Public Highway Corporation has used this technique. 1993). Regarding construction and load-bearing behaviour extradosed bridges represent a seamless transition between external prestressed concrete girder bridges and multispan cable-stayed bridges. In this paper the latest technologies, an extradosed bridge, a cable stayed bridge, a stress-ribbon bridge and truss bridges of the prestressed concrete and steel-concrete composite structure in Japan are introduced. 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. 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 earliest bridge known to incorporate some of the features of an extradosed design is Bridge in Rzuchów near Leżajsk, constructed in Poland in 1980. Extradosed bridges are similar to cable-stayed bridges in that stay cables are used for strengthening. International Association for Bridge and Structural Engineering , Zürich (Schweiz), ISBN 978-3-85748-168-0. If you would like to see this page in another language, please use the language dropdown. Good seismic quality was another important consideration. The first such structure was the Odawara Blueway Bridge, designed and constructed in Japan (Shirono et al. Introduction. It was only adopted six years later when the first extradosed bridge was built in Japan. 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. Canada Line Skytrain Bridge… "Extradosed Bridges" - Schraegseilbruecken mit neuartigem Tragsystem. Es war die erste Extradosed-Bridge außerhalb Japans. The language has been changed due to your browser's language settings. The Shin-Meishin Mukogawa Bridge is located in Japan, north of Kobe, between the Takatsuki and Kobe junctions on the Shin-Meishin Expressway. The Extradosed Prestressed Bridge represents a relatively new bridge type. 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. Further, conventional cable-stayed bridges with spans less than 200m appear to be not economical. Future research on the subject regarding behavior of stay forces under ultimate load is proposed. Extradosed bridge is a midway between a cable-stayed bridge and PSC-box girder bridges. - List of bridges that received the Tanaka Prize "橋の写真館". The concept of extradosed bridges goes back to 1988 with the proposal by the French Engineer Jacques Mathivat. e extradosed bridge is a relatively new type of structure that ha s been developed since the 1990s. For the DYWIDAG Extradosed Tendons, external DYWIDAG Tendons type MC 19 and 27 Ø 15.2 mm with epoxy-coated strands were used. The Extradosed Prestressed Bridge represents a relatively new bridge type. Jump to navigation Jump to search. ICE Virtual Library essential engineering knowledge. They can be peculiarly distinguished from cable stayed bridge using the Pylon height parameter. World Record for Extradosed Bridge with Extradosed Cables in Japan Sannohe-Boukyo Bridge. Quelle: [1] Article von C. Burgoyne /Scantlebury aus The Structural Engineer- 6. 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 bridges are a new structural type of bridge that has been developed mainly in Japan during the last few years. The concept of “extradosed” bridges, where the stay cables are functionally similar to external post-tensioning cables, was introduced by Jacques Mathivat in 1998. Technology meets Tradition: Extradosed Bridge in Japan. 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). This paper shows some examples and the difference between extradosed and cable-stayed bridges in a structural aspect. 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. The Tsukuhara Bridge, part of a road network with the Akashi-Kaikyo Bridge, is the second application of this technique by the Japan … The first Extradosed Bridge was constructed by Japan in 1994. The first such structure was the Odawara Blueway bridge, which was designed and constructed in Japan (Shirono et al., 1993). The extradosed bridge is a relatively new type of structure that has been developed since the 1990s. 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. It was only adopted six years later when the first extradosed bridge was built in Japan. 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. The Extradosed Prestressed Bridge represents a relatively new bridge type. For corrosion protection the external tendons were grouted with an expanding light weight polymer grout. 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. Media in category "Extradosed bridges in Japan" The following 5 files are in this category, out of 5 total. 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. 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. Mit der Canada Line Skytrain Bridge über den Fraser wurde 2008 die erste extradosed Bridge in Kanada erstellt. Extradosed-Eisenbahnbrücke Sapporo ist ein(e) Extradosed-Brücke, Eisenbahnbrücke und Spannbetonbrücke und wurde fertiggestellt im Jahre 1999. 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. The extradosed bridge can be defined as the structure being between the An extradosed bridge employs a structure that is frequently described as a cross between a girder bridge and a cable-stayed bridge. This category has the following 8 subcategories, out of 8 total. After introducing the concept of extradosed bridges by J. Mathivat, this new type of bridge has been constructed in Japan. The extradosed bridge structure developed since 1990s. Das Projekt befindet sich in Sapporo, Hokkaido, Japan. After introducing the concept of extradosed bridges by J. Mathivat, this new type of bridge has been constructed in Japan. Throughout the rest of the world, another 34 of this bridge type have been built, with most countries having only one, or at most a few, examples. This paper shows five extradosed bridges that were designed and built by the author, and explicates the difference between extradosed and cable-stayed bridges in terms of structural aspects.
