What Is Bridge?

Components of Bridge and Their Function

1. Substructure.
2. Superstructure.
3. Adjoining Structure.

#1. Substructure Components of Bridge

1. Piers.
2. Pier cap.
3. Abutments.
4. Wing Walls and the Returns.
5. Foundation.
6. Pile.
7. Pile caps.
8. Bents.

1. Piers

1. Move of loads to the Foundation.
2. Resistance to the lateral forces.

Types of Piers in Bridge Construction:

• The pier could be graded as monolithic as well as cantilevered on the basis of structural connectivity.
• Dependent on the form of the segment pier, it may be categorized as solid or hollow, hexagonal, circular or octagonal, or rectangular.
• Based on the frame design, the pier may be categorized as a single or multiple column bent, a hammerhead or a pier wall type.

2. Pier Caps

3. Abutments

1. The type of abutment you chose.
2. Construction series.
3. The abutments are primarily designed to survive overturning and slipping. More emphasis is on the reliability of the whole system.

4. Wing Walls and Returns

1. The Earth Pressure of the Backfill
2. A surcharge from a live load or a compacting plant
3. Hydraulic loads due to saturated soil conditions

8. Bents

#2. Superstructure Components of Bridge

1. Girders
2. Trusses
3. Barrier
4. Arches
5. Decks

What Is the Purpose of Bridge?

Bridge Components and Their Functions

• Deck: Deck is the portion that carries all the traffic.
• Superstructure: The portion supports the deck slab and girder and connects one sub-structure to the other. That means all the elements of the bridge attached to a supporting system can be categorized as superstructure.
• Sub-structure: The parts of the bridge which support the superstructure and transmit all the structural loads of the bridge to the foundations. For example, piers, abutments, etc.
• Foundation: Foundation is the portion that transmits loads to the bearing strata. Foundation is required to support the piers, bridge towers, and portal frames. Generally, piles and well foundations such as H-pile, bore piles, pipe piles, or precast concrete piles are adopted.
• Girder Or Beam: The beam or girder is the part of the superstructure which bends along the span. The deck is supported by beams.
• Bridge Tower: It is the vertical supporting part used for cable-stayed or suspension bridges. High-strength concrete and Insitu method are adopted to construct the bridge tower.
• Pier: Pier is the part of the substructure that supports the superstructure and transfers loads of superstructure to the foundations.
• Pier Cap: Pier cap is the topmost part of a pier that transfers loads from the superstructure to the pier. It is also known as headstock.
• Bearings: Bearing is a device which supports the parts of superstructure and transfers loads and movements from the deck to the substructure and foundation.
• Pile & Pile Cap: Pile is a slender member driven into the surrounding soil to resist the loads. Pile cap is a thick reinforced concrete slab cast on top of the group piles to distribute loads.
• Bridge Anchor: Bridge anchor is only used in suspension and cable-stayed bridges to resist the pull from suspension cable or counter span of the bridge.
• Suspension Cable: It is used in suspension and cable-stayed bridges for the hanging, supporting and counter balancing of the bridge deck.
