Learn more, © 2020 University of Toronto. Since the concept of the bridge is still relatively new, there is no clear definition and design document or guideline for extradosed bridge s. Some clarifying conclusions have been found, such as the necessity to supplement extradosed prestress by additional centered prestress. Un parti original: la précontrainte extradossée.In: Travaux, n. 733 (July - August 1997), pp. An extradosed bridge is a bridge type that combines a prestressed girder bridge with cable-stayed bridge design concepts. However, cable pylons pose difficulties in design and analysis because of their complicated loading conditions in the anchorage zone. 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. The key feature visually distinguishing the extradosed bridge from the cable-stayed bridge is the low tower height above the deck and hence shallow stay angles. AECOM undertook detailed investigation of this bridge form by extensive finite element modelling, the model from which is shown in Figure 3. The extradosed bridge is the first of two to be designed in order to carry out an economical competitiveness analysis between the cantilever constructed box-girder bridge presented above, and two bridges with cables, a cable-stayed bridge and an extradosed one.
