What are beams?

Beams are buildings that civil engineers and construction professionals construct and use to support larger structures. These structural components support a building’s weight in order to maintain stable and robust working conditions.

If you work in the fields of construction, engineering, architecture, or structure design in general, you may need to be familiar with the various types of beams in order to choose the one that will work best for your project and understand how it will affect the cost and shape of the building you are helping to build.

Classification of beams

Engineers and construction workers employ a variety of beam types to achieve various goals. Professionals base their determination of the various beam types on these classifications:

Although experts classify each beam according to these categories, a beam may apply to more than one class. However, experts frequently classify beam types according to a certain feature or distinction from other beams.

Types of beams

It’s crucial to comprehend how beam types differ from one another if you’re interested in learning about the design and application of specific building components or if you’re pursuing a career in the building or engineering industries. Heres a list of different types of beams:

Cantilever beam

Professionals can classify a cantilever beam by its support conditions. This horizontally extending structural component has one end attached to the rest of the structure and the other end free. Construction experts use cantilever beams to build certain bridge types, bay windows, and balconies.

Simply supported beam

Professionals can also categorize simply supported beams based on the conditions of that support. They are pinned to two different types of supports and fixed on both ends. A simply supported beam has a rotating feature at one end that can be moved, while the other end is stationary and attached to a stationary support structure. These beams are used by engineers and construction experts to construct buildings and suspension bridges that are earthquake resistant.

Overhanging beam

Building contractors and others fasten sagging beams to two stationary support points. However, this beam hangs past its supporting structure at least on one end. When constructing balconies and roof extensions, experts can use overhanging beams. They’re particularly well-liked in the architecture of hotels and apartment complexes.

Double overhanging beam

Similar to an overhanging beam, a double overhanging beam extends past its fixed point of support on both sides rather than just one. These beams may be used by experts in structures with floors that rise above lower levels, such as enclosed balconies or buildings housing tourist attractions with glass floors.

Continuous beam

Professionals classify continuous beams based on their support conditions. These beams are typically longer than other beams and frequently have multiple fixed support points. These beams can be used by engineers and construction experts in a variety of structures, such as bridges, rooftop additions, and multi-story buildings.

Fixed beam

Fixed beams are also referred to as built-in beams. Theyre fixed at both ends and cannot move. This provides very stable support for the structure. Professionals use fixed beams when building column-like structures.

Trussed beam

Any beam strengthened by a truss is referred to as a trussed beam by experts. A truss is a triangle-shaped support structure. Professionals in construction and building design categorize trussed beams according to these support conditions. Trussed beams are incorporated into the design of some bridges and commercial structures, including warehouses.

Elastic foundation beam

Professionals classify elastic foundation beams by their support system. These beams are supported by an elastic foundation that offers constant support to both halves of the beam. A railroad track is a typical application of a trussed beam.

Spring support beam

A spring support beam closely resembles a cantilever beam. It has one fixed end, but a spring mechanism supports the other end.

Steel beams

Professionals categorize steel beams according to the materials they are made of rather than the conditions of their support. Professionals use these beams in a variety of applications. Typically, steel beams have two parallel horizontal sections that join with a single vertical section. Steel beams are given a shape that resembles the capital “I” as a result. “.

Reinforced concrete beams

A support structure protected by a concrete slab are reinforced concrete beams. These strong beams are used by experts to build larger, weight-bearing structures like dams, parking garages, stadiums, and piers.

Timber beams

Timber beams are made of various types of wood and frequently have trusses. Despite the fact that timber beams can be useful in construction, experts frequently use beams made of other materials, such as steel or concrete. Construction workers do, however, occasionally use timber beams to enhance a home’s interior architecture because they are frequently visible.

Composite beams

A type of beam made of two or more materials is called a composite beam. Professionals classify composite beams as a subtype of reinforced concrete beams.

Rectangular beams

Professionals categorize rectangular beams by their cross-section. Theyre known as the most commonly used beam in construction. Rectangular beams experience top compression in addition to bottom tension for the majority of their reinforcement.

T-section beam

T-section beams earn their name from their shape. Professionals categorize this beam based on its cross-section. Compared to other support beams, T-section beams can be more flexible and cost-effective. When used, t-section beams can lower the height from floor to ceiling of a space, enabling construction workers to use them when they need to be cost- and space-efficient.

L-section beam

The cross-sectional shape of L-section beams, which resembles the capital “L,” gave them their name. Professionals frequently employ these beams when building stairs and corners.

Straight beam

Any type of beam with a straight shape and no cross-sections is referred to as a “straight beam” in a broader sense. Steel, composite, wood, and concrete are just a few of the materials that manufacturers can use to create these beams.

Curved beam

Fixed on both ends, curved beams have a “c” shape. For stability, these beams frequently have two support points. Professionals use curved beams to construct round houses, buildings with circular rooms or towers, gazebos, arches, and other structures.

Tapered beam

Tapered beams feature two ends that vary in width. Although there are many ways in which professionals can use tapered beams, construction workers frequently use tapered beams in more ordinate buildings and structures, such as churches.

Statistically determinate beam

Statistically determinate beams are categorized by their equilibrium conditions by engineers, architects, and construction workers, which can aid experts in determining the amount of force a beam can withstand. These beams aid in the construction of buildings and structures, such as bridges, that may be subject to varying degrees of stress.

Statistically indeterminate beam

Professionals categorize statistically indeterminate beams by their equilibrium conditions, much like a statistically determinate beam. Statistically uncertain beams are supported more than is necessary, resulting in complete structural stability.

Cast in situ concrete beam

To ensure specific conditions, experts create cast-in-place concrete beams on the construction site. These beams can be created by construction workers by pouring concrete into a mold and letting it cure there.

Precast concrete beam

Precast concrete beams are made by experts in a plant or factory, unlike cast in situ concrete beams, and are then transported to a specific construction site. To ensure a high-quality outcome, manufacturers put these beams through rigorous testing and treatment before shipping.

Prestressed concrete beam

Before they are cast, experts test and exert force on pre-stressed concrete beams. In order to create a solid beam for high-quality construction projects, this can help.

Deep beam

Deep beams can help reduce the strain on other beams because they are frequently wider than other beams. These beams are used by experts to build floor diaphragms, shear walls, and the lower levels of high-rise structures.

Girder beam

Another beam and trusses are used to connect girder beams, which can have a square or rectangular shape. Because girder beams can support more weight than most beams, experts frequently use these beams. Girders are occasionally used by engineers and construction workers to build bridges and flyovers.
