The classification of bridges can be different according to the ?.classification criterion: what are the criteria?

the classification criteria are: Function, materials, structure, type of spans (independent, continuous, cantilever), the importance of the work (current - non-current) or according to specific criteria to families structures (arch type for bridges or curved sheets for shrouds types of bridges).

 

These ranks can be crossed with each other to form subdivisions.

Based on Action

• Beam bridges
• Cantilever bridges
• Arc bridges
• Suspension bridges
• Cable-stayed bridges
• Truss bridges

Based on Material Used

• Concrete bridge
• Steel bridge
• Timber bridge
• Composite bridge

Based on Purpose

• Road bridges
• Rail bridges
• Rail and road bridges
• Pedestrian bridges
• Aqueduct

Based on Type of Support

• Simply supported bridges
• Continuous bridges
• Fixed bridges
• Cantilever brdiges

Types of bridges

1 divide bridges in terms of use

1-1 - bridges of  cars and pedestrians.

1-2 - railway bridges.

1-3 - pedestrian bridges.

1-4 - bridges of pipelines] oil pipelines - water - sewage].

1-5 - temporary bridges.

 

2 divide bridges in terms of building materials

2-1 - concrete bridges.

2 -2. bridges of concrete cast on site.

2 -3 bridges of  precast concrete.

2 -4. bridges of prestressed concrete cast on site.

2 -5.prestressed precast concrete bridges .

2-6 - metal bridges

2-6 -1. bridges of metal trusses.

2-6 -2 bridges of  metal beams.

2-6 -3 suspended metal bridges 

2-7 - concrete and metal bridges

2 -8. suspended concrete bridges.

2 -9. wooden bridges

2 -10. stone bridges

 

3 divide the bridges on the basis of form:

31 bridges straight dorsal] DECK - Straight Bridge [.

32 bridges curved dorsal] DECK - Skew Bridge [.

33 straight bridges tunnel] THROUGH - Straight Bridge [.

34 bridges curved tunnel] THROUGH - Skew Bridge [.

components of bridge

•A bridge is a structure providing passage over an obstacle without closing the way beneath. •The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. •The obstacle to be crossed may be a river, a road, railway or a valley.   Classification of Bridges   1.Classification of Bridges (According to form (or) type of superstructures) •Slab bridge •Beam bridge •Truss bridge •Arch bridge •Cable stayed (or )suspended bridge   2.Classification of bridges (According to material of construction of superstructure) •Timber bridge •Concrete bridge •Stone  bridge •R.C.C bridge •Steel  bridge •P.C.C bridge •Composite bridge •Aluminum bridge   3. Classification of bridges (According to inter-span relationship) •Simply supported bridge •Cantilever  bridge •Continuous  bridge   4. Classification of bridges (According to the position of the bridge floor relative to superstructures) •Deck through bridge •Half through or suspension  bridge   5. Classification of bridges (According to method of connection of different part of superstructures) •Pinned connection  bridge •Riveted connection  bridge •Welded connection  bridge   6.Classification of bridges (According to length of bridge) •Culvert  bridge(less than6 m) •Minor bridge(less than6 m-60m) •Major bridge(more than60 m) •Long span bridge(more than120 m)   9.Classification  of  bridges (According to function) •Aqueduct bridge(canal over a river) •Viaduct(road or railway over a valley or river) •Pedestrian bridge •Highway bridge •Railway bridge •Road-cum-rail or pipe line bridge  

The brothers answered the question accurately and many thanks to them and you

1-Materials made from them bridge( timber. stone. masonry . iron .steel .concrete. prestressed concrete. cable)  

2- The type of work that will be subjected a bridge.)highway .railway )

3-(standard specification required

4-type loads (tensile forces, pressure or joint

5- impact factors 

I have been reading many good answers and I agree the size depends on the usage and the materials used.

Thank you for the invitation.

I would say the purpose, the capacity and the type of design.

Many early bridges are now classified as ancient monuments, and must be repaired to match original materials, etc. Many early bridges were built and maintained by the Church; these are almost entirely of stone construction. In the eighteenth century, the building of the canal systems caused many bridges to be built, in this case mainly in brickwork. In the1830s and1840s, the development of the railways caused another spate of bridge building, this time, mainly in cast iron. In the present century, bridges have been designed and built purely as highway bridges. Due to increasing vehicle loads, considerable extra stress has been put on existing bridges, often well in excess of their designed load.

Thanks, Agreed with colleagues answers, especially Mr.Mustapha's answer and Mr.Yaqoob's answer.

the classification criteria are

position of carriageway eg.Deck type/Through type/semi through type ;

type of traffice carried.eg.highway/railway etc ;main sructural system

 example ; girder/rigid frame/arch/cable stayed/suspendion etc.and

Foundation eg.open/well/pie etc
