The Extradosed pre-stress bridge concept is relatively new in the field of Structural and Bridge Engineering. In the approximately 13 years since the original edition of the Bridge Engineering Handbook was published in 2000, we have received numerous letters, e-mails, and reviews from readers including educators and practitioners commenting on the handbook and suggesting how it could be improved. An extradosed bridge has a cable attached to the main tower to reinforce the bridge's girders. endobj <> 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. 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.

The bridge designs include a new extradosed river bridge with mainline approach spans (Bridge 82045) and ramp bridges (Bridges 82047 and 82048), and approach panels with the minimum amount of grading required to ensure that adequate erosion control measures and best management practices are employed to minimize any uncontrolled release of sediment into the St. Croix River.

Engineering bridge width assumptions are provided in the detailed cost summaries in Appendix E. Multiple extradosed/cable-stay structures would need to be considered for alternatives greater than 140 feet in width. The design variables considered are the extradosed cable areas and prestressing forces, the deck prestressing forces and tendon areas and the towers and deck cross-sections. Alternative 8. It is the longest multi-span extradosed bridge in the world, with a main bridge length of 1,920 m (6,300 ft). The first Extradosed Bridge was constructed by Japan in 1994. A ceremony has been held to mark the start of construction of an extradosed bridge over the Brahmaputra River in the Indian state of Assam. An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge.

Mathivat was inspired by the -design used by Swiss engineer Christian Menn for the Ganter Bridge (Switzerland, Figure 2) which was completed in 1980. Users initiate high-level parametric modeling by defining span length, layout lines, cross section, and other geometric and structural specifications.The Bridge Modeler then assembles frame, shell, and solid objects, and connects them with link elements, to automatically create bridge objects.
