Beam Bridge

Introduction of Beam Bridge

A beam bridge is a structure in which a road is built over it without physical obstruction (such as water body, valley, road, or rail ).

The function of the beam bridge is to pass through the barrier. A beam bridge should be built where it is difficult or impossible to get from one place to another.

Many different designs of bridges serve a specific purpose. Bridges are built for a specific purpose in different situations. Bridge designs vary depending on various factors, such as the work of the bridge, the construction of the bridge, and its location. In addition, it depends on the material used to build the bridge and its quality.

What Is a Beam Bridge?

The Beam Bridge is also known as the Second Stringer Bridge. The design for this type of beam is fairly simple structural. It is supported by an abutment or pier at each end.

A beam bridge is a commonly used bridge. A Beam bridge is a type of girder bridge. The bridge’s main purpose is to provide a way to go from one end to the other.

Beam bridge is the simplest and cheapest type of bridge.

The most basic form of beam bridge consists of a horizontal beam, supported by piers or abutments at each end. In this type of bridge, the weight of the beam pushes directly down on the pillars or abutment.

This type of beam should be strong enough not to bend under force due to its own weight and traffic. When compression force is applied to a load beam. Then the top edge of the beam feels compression. And tension force is applied to the bottom edge.

At the beginning of the bridge, simple beam bridges were made of wooden planks or stone slabs.

Bridges in modern infrastructure are usually made of steel or reinforced concrete or a combination of both. Materials like solid reinforced, precast concrete or post-tensioned, etc. can be used. Modern bridges include girder, plate girder, and girder bridge, etc. in beam bridge.

Beams can be used for different spans in bridges. Beam bridges are used in some viaducts. Like the Fungjiang Bridge in China, it is made from various beams supplied on the pier.
