What Are The Main Differences Between Cable Stayed Bridges And Suspension Bridges

The difference lies in how the cables are connected to the towers. Deck is supported by two main cables through secondary cables hangers.

Cables and towers are used as supporting system.

What are the main differences between cable stayed bridges and suspension bridges

. 9 Cable-Stayed Bridges Cable-stayed bridges may appear to be similar to suspension bridges but in fact they are quite different in principle and in their construction. And 5 the relatively small size of the bridge elements 1. In general a cable stayed bridge is less efficient in carrying dead load than a suspension bridge but is more efficient in carrying live load.

There is one important difference we should note between suspension bridges and cable stayed bridges. In suspension bridges the cables ride freely across the towers transmitting the load to the anchorages at either end. Cable stayed bridge 8.

The compression pushing up balances out the tension pushing down allowing the bridge to remain upright. They require much less steel cable and use more precast concrete sections which accelerates construction. In cable-stayed bridges the cables are attached to the towers which alone bear the load.

High strength concrete and Insitu method are adopted to construct the bridge tower. It is the vertical supporting part used for cable stayed or suspension bridge. Main supporting structure is above deck line.

Cable-stayed bridges a re. There are two major classes of cable- stayed bridges. Increased stiffness comparing with suspension bridges.

The excitation forces acting on cable supported bridges are aerodynamic by nature but are for a large part set into play by the underlying structural dynamics of the bridge structures. The most economical span length for a cable stayed bridge is 100350 m though some designers have extended this range to as much as 800 m. Fan type which are the most efficient and Harp or parallel type which allow more space for the fixings.

Cable supported bridges are flexible structures which may be excited into oscillations by the wind. Bot structures have following similarities. Pier cap is the topmost part of a pier which transfers loads from superstructure to the pier.

It is also known as headstock. There have been some problems with cable. This can be problematic should deck replacement be necessary.

The principles of cables and towers are at each end with strong. Thereforethistypeofbridgesarebecomingmoreandmorepopularandare usually preferred for long span crossings compared to suspension bridges. Cant figure out of any other similarity -.

4 the efficient and fast mode of. Cable stayed bridges have good stability optimum use of structural materials aes-theticrelativelylowdesignandmaintenancecostsandefficientstructuralcharacter-istics. In suspension bridges the cables ride freely across the towers transmitting the load to the anchorages at either end.

This has the disadvantage compared to the suspension bridge that the cables pull to the sides as opposed to directly up requiring the bridge deck to be stronger to resist the resulting. The principal difference between the suspension bridge and the cable stated bridge is the fact that suspension bridge was constructed by the ancient communities using rope and bamboo. Beam bridges are acted upon by compression and tension.

By contrast the cable tension in a cable stayed bridge is distributed over many anchorages along the deck. In a suspension bridge the main cable tension is concentrated in the anchorages at each end. In short cable-stayed bridges bear the road-deck weight differently are faster to build and require less construction materials than suspension bridges.

The paper discusses the various types of dynamic wind effects. Deck is supported by tower directly through cables. The difference lies in how the cables are connected to the towers.

When a suspension bridges cables anchorages and suspenders are under tension the bridges towers are under compression.
