Around the world, beam bridges are a well-liked and often utilised option for bridge design. They are built by putting a beam over two abutments or piers to create a bridge that is simply supported, as its name implies. One of the main causes of their widespread use is their straightforward design. We will go through the characteristics, varieties, and advantages of beam bridges in this tutorial.

Types of beam bridges

Concrete, steel, and wood are just a few of the materials that may be used to construct beam bridges. In rural places, where they may fit in with the surroundings, wooden beam bridges are frequently employed. Steel beam bridges are used for locations with high traffic because of their strength and endurance. Bridges made of reinforced and prestressed concrete beams are also often utilised because of its high capacity for carrying loads and capacity to cross greater distances. Bridges with girders, plate girders, and box girders are the most prevalent forms of beam bridges.

Beam bridges are built in a variety of ways. In one design, a deck is built on top of multiple beams that have been placed side by side. Another design entails holding a deck between two major beams, one on either side of the bridge. I-beams, trusses, or box girders might be used as the primary beams.

Beam bridge: Specifications

Beam bridges have a straightforward design and are supported at either end by an abutment or pier. Since no time is conveyed through the support, they are referred to as merely supported. The concrete components may be post-tensioned, prestressed, or reinforced.

Beam bridges can be through or partially through by bracing them over the top. They can also be constructed with a deck across the top of multiple beams placed side by side or with a primary beam on either side supporting a deck in the space between them.

Use of Beam Bridge

Because they are straightforward and affordable, beam bridges are a popular option for many applications.

Small streams or rivers that are neither deep or wide enough to call for a more sophisticated bridge structure are frequently crossed in rural regions by beam bridges. Beam bridges are utilised in metropolitan areas to connect neighbourhoods, parks, and other locations with heavy foot and car traffic. Beam bridges may be swiftly built due to their straightforward design and construction, making them appropriate for temporary or emergency scenarios.

Beam bridges also have the advantage of being made of a variety of materials. Depending on the exact needs of the bridge, they may be constructed from wood, steel, concrete, or a mix of these materials. Materials are selected based on a number of variables, including the span of the bridge, the volume of traffic, and the local environmental conditions.

Bridge made of beams: drawbacks

Being unable to accommodate larger spans, which call for a different kind of bridge design, is one of the main disadvantages of beam bridges. Beam bridges can only be used by light cars, bicycles, and walkers as they are unable to carry very heavy weights or large quantities of traffic.

Beam bridges also have the drawback of being particularly susceptible to earthquakes, which can seriously harm the bridge's construction and cause it to disintegrate or collapse. Beam bridges might not be the ideal option for regions that are vulnerable to earthquakes or other natural catastrophes as a result.

Beam bridges must also be maintained on a regular basis to preserve their durability and structural integrity. This can be expensive and time-consuming, particularly if the bridge is situated in an isolated or challenging location.
