4 types of bridges

Cantilever Bridge

∙ Crosses large spans often rivers or bays without the benefit of having a center support

∙ Crosses up to 1
,800 feet in length

∙ Extends over the opening from both sides

∙ Each half of the bridge is a cantilever, (it is supported on just one end) like to joining diving


∙ The two cantilevers connect in the center of the bridge

∙ The center support is norm
ally smaller than the two outer supports

Beam Bridge

∙ The beams generally are located at fixed gaps

∙ A concrete deck is placed on the main flange to provide assistance against buckling

∙ Bridge deck forms are constructed according to the traffic load a
nd other design characteristics

∙ Beam bridges are helpful for short spans.

∙ Long distances are normally covered by placing the beams on piers

Beam bridges may be costly even for rather short spans, since expensive steel is required as a

construction mat

∙ When long spans are required to be covered, beam bridges are extremely expensive

Building of the support piers may not always be possible due to the limitation of space.

Bridge beams are likely to droop between the piers, due to the different bridg
e loads acting


The sagging tendency is increased when the bridge span or load is increased.

Suspension Bridges

Incas used suspension bridges for livestock and farming purposes

suspension bridges are suspended between two high locations

held up by cables and ropes

downward arc that the surface must have in order for it to support the weight of people and


While these types of bridges can support low
weight traffic, they would not be sufficient for

modern automobiles or trains

The design allows them to cover longer distances than other types of bridges

are much cheaper to build, which makes them very attractive

because of the height of the suspension bridge boat traffic continues, which is not possible

with other types o
f bridges

Arch bridges

one of the oldest types of bridges

been around for thousands of years

have great natural strength

Commonly built of stone or brick and often reinforced by concrete or steel.

Instead of pushing straight down, the load of a
n arch bridge is carried outward

The weight is transferred to the supports at either end

The supports, carry the load and keep the ends of the bridge from spreading out

Expose yourself for the protection of another

Make defense against any assailing danger

Take the place of the fallen of the weak
