What are abutments in a bridge?

A bridge abutment is a structure which connects the deck of a bridge to the ground, at the ends of a bridge span, helping support its weight both horizontally and vertically.

What is a pier in a bridge?

Pier, in building construction, vertical loadbearing member, such as an intermediate support for adjacent ends of two bridge spans. In foundations for large buildings, piers are usually cylindrical concrete shafts, cast in prepared holes, but in bridges they take the form of caissons, which are sunk into position.

What is the difference between pier and bridge?

Why are abutments used in bridge construction?

Abutments are used at the ends of bridges to retain the embankment and to carry the vertical and horizontal loads from the superstructure to the foundation, as illustrated in Figure 12.1-1.

What is bridge approaches?

The approach slab provides a transition between roadway pavement and the bridge. The approach slab acts as an intermediate bridge to span the portion of embankment directly behind the abutment/backwall which was excavated to construct the abutment/backwall.

How are bridge piers made?

When bridges requiring piers are built over a body of water, foundations are made by sinking caissons into the riverbed and filling them with concrete. Next, the anchorages are built on both ends, usually of reinforced concrete with embedded steel eyebars to which the cables will be fastened.

What is permanent bridge?

A dental bridge is a device used to fill the space where a tooth is missing. Typical permanent bridges consist of a pontic (a filler tooth) that is attached to two surrounding abutments (dental crowns). Once complete, this dental bridge structure is bonded into the mouth.

What’s the difference between a pier and an abutment?

Abutments support the ends of the bridge and transfer the loads from the superstructure into the ground. Pier are the internal supports of the bridge. Abutments are the ends supports of the bridge. Pier can use more than two in bridge construction. Pier are constructed between the abutments.

Why are there two abutments on a bridge?

Most Bridges with a single span have two abutments that give lateral and vertical support. Bridge Abutment plays an important role in retaining walls to resist lateral movement of the bridge approach’s earthen fill. Bridge piers are raised structure that sits in a body of water in order to support a bridge.

Why do you need piers on a bridge?

Piers support the span of the bridge and transfer the loads from the superstructure to the substructure. Piers should be strong enough to take both horizontal load and vertical load. Multi-span bridges require piers to support an end of spans unsupported by abutments.

What’s the difference between a retaining wall and a pier?

In that case, the retaining walls are the abutments. In addition to abutments, bridges with more than one span also have piers. A pier is an intermediate bridge substructure component providing support somewhere in between the two abutments. Piers can take many different forms and can look very dif… Loading…
