Extradosed bridges are perfect example for combination in structural configuration of, stay cable bridges for aesthetics and girder bridges for their durability, strength and ease of construction merger of both bridge configuration leads to economical bridge construction in terms of design and construction costs savings. The purpose of this thesis is to provide insight into how different geometric parameters such as tower height, girder depth, and pier dimensions influence the structural behaviour, cost, and feasibility of an extradosed bridge.

Mackenzie, canadasextradosed cable-stayed bridge, which also is named partial cable-stayed bridge, is a novel style bridge between girder bridge and cable-stayed bridgeto provide a summary of the trends of the extradosed bridges built to-date. Abstract extradosed bridges combine the main elements of both a prestressed box girder bridge (pbg) and a cable-stayed bridge with their shallow cable-stays and stiff decks they represent an economic alternative to pbg bridges and cable-stayed bridges for main spans of 100 to 200 m. Extradosed bridge shall have a similar behavior to the prestressed bridge´s, thus avoiding high stress oscillations of stay cables and, consequently, avoiding fatigue. Bridge consists of 3360 feet of main bridge with 18-ft deep precast concrete box girder superstructure segments and up to 234-ft tall concrete towers the extradosed main bridge has four main spans of 600.
Characteristics of an extradosed bridge • shorter tower than cable stayed • shallower girder than a girder bridge, but deeper than a cable stayed bridge. For extradosed bridges with a concrete deck, a combination of the stay cable forces and the prestressing forces inside the deck section may be targeted to eliminate the bending moment along the entire length of the deck under dead load. Iv extradosed railway bridges with the stiffening girder in a central position by michiel bevernaege master's dissertation submitted in order to obtain the academic degree of.
This paper is also intended to show the adopted structural trends by presenting existing extradosed bridges, bridges under construction, and newly designed bridges. Extradosed bridge proofchecking methodology extradosed bridge is a hybrid structure of balanced cantilever and cable stayed bridge it is recommended for the spans varying from 100 m -300m length. 1 abstract this thesis studies a structural solution in a preliminary level of an extradosed railway bridge for high-speed trains, it uses a pre.
