Seminar on cable stayed bridge
- 1. SEMINAR ON CABLE STAYED BRIDGE DEPARTMENT OF CIVIL ENGINEERING NATIONAL INSTITUTE OF TECHNOLOGY PATNA 800006 BY:- SUJEET KUMAR [ M.TECH ] STRUCTURAL ENGINEERING ROLL NO. 1723011
- 2. INTRODUCTION • A cable-stayed bridge has one and more towers, from which cables support the bridge deck. • A distinctive feature are the cables which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. • This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers.
- 3. CABLE STAYED BRIDGES: Cable-stayed bridges have towers, but cables from the tower go directly to the road deck, instead of spanning from tower to tower. Fig. 3 CABLE STAYED SUSPENSION BRIDGE RUSSKY BRIDGE , RUSSIA
- 4. COMPONENTS • A cable stayed bridge is a type of bridge in which the deck (the load-bearing portion) is hung on suspenders. • Cables-suspend the roadway(deck) via hangers. • Towers- stabilize wire cables (offer little support).
- 5. EVOLUTION OF CABLE STAYED BRIDGE • Cable-stayed bridges date back to 1595, where designs were found in Machinae Novae, a book by Venetian inventor Fausto Veranzio. Many early suspension bridges were cable-stayed construction, including the 1817 footbridge Dryburgh Abbey Bridge, James Dredge's patented Victoria Bridge, Bath (1836), and the later Albert Bridge (1872) and Brooklyn Bridge (1883). • Their designers found that the combination of technologies created a stiffer bridge. John A. Roebling took particular advantage of this to limit deformations due to railway loads in the Niagara Falls Suspension Bridge.
- 7. CABLE STAYED BRIDGE THROUGHOUT THE INDIA Vidyasagar setu in kolkata is the longest cable stayed bridge in india.
- 10. ADVANTAGE • Compared to other bridges types, the cable stayed is used for longer spans than used for cantilever bridges and shorter than required in suspension bridge. • A cable stay bridge is cheaper to built than suspension bridge over a short distance. • Good stiffness , large ground anchorages are not required. • It is a modern looking bridge economical for construction, well balanced.
