A suspension bridge suspends its load from main cables that run along both sides of the structure. The beam bridge is the oldest and most common type of bridge. A beam bridge is a horizontal structure, with beam supports at each end, and piers between the beams.
It is any type of support beam or structure.
Another type of bridge besides the beam bridge is the suspension bridge and one example is the Golden Gate Bridge in San Francisco ,California . Also another bridge is the cable stayed bridge and one example of that is the Sunshine Skyway Bridge in Tampa ,Florida. If you wanna find more about it ask more questions ...
Arch bridges are in the shape of an upside down "U" with mainly steel beans, while supension bridges have one or two Major verticle beams with strong wire connecting to the bridge.
Most highway bridges and railroad bridges are simple beam bridges. In this type of construction, the road surface or deck is supported by a series of longitudinal beams made of concrete, steel or timber. These in turn rest on bearings, which reston piers or abutments.
It involves a configuration the combines strength and productivity. The designing uses SAE steel grades (essentially an amalgamation of carbon and alloy steels) which renders the framework strong yet complex. It ensures that any beam, strut or tie ends only undergo tensional or compressional forces.
It depends on the type of beam, the material, whether it is a bridge span or cantilever, the allowable deflection and safety margin needed. We need a lot more data on the application.
