What factors need to be considered when building suspension bridges?
While constructing a pedestrian bridge, there are several important factors to take into consideration.
- Width. The width of a pedestrian bridge is dependent on the type of traveller and amount of traffic the bridge will receive.
- Site Conditions.
- Geotech Analysis.
What are the specifications of a suspension bridge?
A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The basic structural components of a suspension bridge system include stiffening girders/trusses, the main suspension cables, main towers, and the anchorages for the cables at each end of the bridge.
What is good about the design of a suspension bridge?
Modern suspension bridges are light and aesthetically pleasing and can span longer distances than any other bridge form. They are also among the most expensive bridges to construct. Though suspension bridges can be made strong enough to support freight trains, they have nearly all been designed for automobile traffic.
What are the constraints of a suspension bridge?
List of the Disadvantages of Suspension Bridges
- Suspension bridges can struggle to support focused heavy weights.
- There is less flexibility with a suspension bridge.
- High winds can cause a suspension bridge to start vibrating.
- Some access below the deck may be necessary during construction.
What do you think are the 3 most important considerations when designing a bridge?
Mostly, engineers consider three types of loads; dead loads, live loads and environmental loads: Dead loads include the weight of the bridge itself, plus any other permanent object affixed to the bridge.
What factors influence bridge design?
The choice of type of a bridge generally depends upon the following factors:
- The nature and bed conditions of river or stream.
- The nature and volume of traffic to be carried.
- Whether navigation is done in the river or not.
- Hydraulic data collected at the site.
- The climatic condition of the area.
What makes a suspension bridge strong and stable?
Suspension bridges are strong because the force on the bridge gets spread out. The weight of the cars or trains or horses, whatever’s traveling across it, pulls on the cables, creating tension. Those cables then pull down on the towers and also pull on the anchors on either end of the bridge, to hold up the deck.
What are the pros and cons of a suspension bridge?
Pros of a Suspension Bridge
- It can span over long distances.
- It is inexpensive to build.
- It is easy to maintain.
- It is incredibly versatile.
- It is aesthetically pleasing.
- It is vulnerable to the wind.
- It has load limitations.
- It costs time and money.
What are pros and cons of suspension bridges?
How are suspension bridges supported?
Suspension bridges get their name from the fact that the roadway is suspended by cables from two tall towers. Most of the weight is supported by the two towers. They, in turn, pass the compression forces from the cables directly into the ground. Suspension bridges also have smaller cables called suspenders.
What are the four bridge design considerations?
In summary, the pedestrian bridge design process includes seven important considerations: trail width, site conditions, geotechnical analysis, abutment plan, permitting, safety and durability.
