What’s the use of bridge?
A bridge is a structure built to span a physical obstacle, such as a body of water, valley, or road, without closing the way underneath. It is constructed for the purpose of providing passage over the obstacle, usually something that is otherwise difficult or impossible to cross.
What are the most common types of bridges?
The most common types of modern bridges include: beam, truss, arch, cantilever, cable-stay and suspension. A beam bridge, the simplest type of bridge, is made of long beams of wood, metal or concrete that are supported at each end by piers.

What are the two types of bridge?
Types of Bridges
- Arch Bridges. Arch bridges – use arch as a main structural component (arch is always located below the bridge, never above it).
- Beam Bridges.
- Truss Bridges.
- Cantilever Bridges.
- Tied Arch Bridges.
- Suspension Bridges.
- Cable-Stayed Bridges.
- Moveable Bridges.
What are different parts of a bridge?

- Piers.
- Abutments.

What is the strongest part of a bridge?
Overall the beam bridge appeared to be the strongest type, although the truss bridge was more rigid up until the point of failure. I observed that all of the truss bridge failures involved the separation of an end post joint, which were glued.
What are the 6 types of bridges?
There are six basic bridge forms: the beam, the truss, the arch, the suspension, the cantilever, and the cable-stay.
What is the load of a bridge?
There are 3 kinds of forces that operate on any bridge: the dead load, the live load, and the dynamic load. Dead load refers to the weight of the bridge itself. Like any other structure, a bridge has a tendency to collapse simply because of the gravitational forces acting on the materials of which the bridge is made.
What are the four major types of bridges?
There are four basic types of bridges. These are Beam bridges, Arch bridges, Cantilever bridges and Suspension bridges.
What are the pillars of a bridge called?
A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers.
What makes a bridge so strong?
Suspension bridges are strong because the force on the bridge gets spread out. The weight of the cars or trains or horses, whatever’s traveling across it, pulls on the cables, creating tension. Those cables then pull down on the towers and also pull on the anchors on either end of the bridge, to hold up the deck.
What are some examples of beam bridges?
Lake Pontchartrain Causeway in Louisiana, the world’s longest over-water bridge, is an example of a beam bridge. The causeway’s 24 mile length is made up of 2,243 separate spans on the southbound lane and 1,500 spans on the northbound lane.
