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.

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.
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.
