20 Types of Construction Beam & Their Uses

Introduction of Construction Beams

There are various types of construction beams are used in the buildings depending upon their function and the nature of work. Beams are generally constructed to support one or more points and the effective length of the beam between two and supports is known as the span of the Beam.

The Beam is basically a horizontal structural element that is constructed to support the slab and withstand the loads coming from the building. The Beam is connected to the columns to which it transmits the total load up to the foundation.

This type of beam allows the horizontal movement of beam and generally undergoes both shear stresses as well as bending moment.

Uses of Simply Supported Beam

• Simply supported beams are widely used in the construction of residential buildings.

6. Continuous Beam

The continuous beam is a type of beam which is supported by more than two supports. In the case of the continuous beam, the end support of the continuous beam may be simply supported or fixed. Continuous beams have more stability as compared to other types of construction beam.

Uses of Continuous Beam

• The continuous beam is generally used in the construction of large span bridges whose length is too long.
• Continuous beams are also used while constructing long span slab and structures which has more than two supports in a continuous manner.

7. Fixed Beam

The Fixed-beam in defined as the type of construction beam whose both ends are fixed rigidly in the walls or any other structure. The Fixed beam cannot be able to rotate at its end.

The Fixed-beam does not allow movement in the vertical direction and the rotation of the beam. Fixed beam only undergoes shear stresses and there is no moment are produced at the end of the fixed beam.

Uses of Fixed Beam

• The Fixed beams are used in the construction of trusses.

8. Cantilever Beam

A cantilever beam is a type of construction in which one end of the cantilever beam is fixed and the other end of the cantilever beam is free.

The cantilever beam is constrained at one end with the other end is extending freely outwards direction. When the cantilever beam is loaded the beam transfers load to its fixed end under the action of Bending.

Uses of Cantilever Beam

• Cantilever beams are used in the construction of balconies and Cantilever slabs etc.

9. Overhanging Beam

Overhanging beam are defined as the types of construction beams whose end portion of the beam extends beyond the supports. The properties of the overhanging beams are same as the cantilever beam and simply supported Beams.

The overhanging beams are classified into two types such as overhanging beam on right side and overhanging beam on left side. The beam whose end portion extends beyond the supports on the right side is known as the overhanging beam on the right side.

The beam whose end portion extends beyond the supports in the left direction is known as the overhanging beam on left side.

Uses of Overhanging Beam

• An overhanging beam is used where it is not practical to provide a support to the beam at one end.
• You will frequently encounter overhanging beams in a floor beam which extends beyond the exterior wall of a building to support a balcony.
• It is also used to support roof extensions as in the picture below.

10. Double Overhanging Beam

A double overhanging beam is a type of construction beam whose both ends extend beyond its supports.

11. Straight Beam

Straight beams are the type of construction beams which has a straight profile. The straight beam has an equal cross-section area throughout the length of the beam.

Uses of Straight Beam

• Beams are the horizontal members used to support vertically applied loads across an opening.
• In a more general sense, they are structural members that external loads tend to bend, or curve.

12. Curved Beam

The curved beam is a type of construction beam boots shape is curved and the centre of gravity of the curved beam always follows a curve.

Uses of Curved Beam

• The curved beam is used for the construction of decorative structures or buildings.

13. Tapered Beam

The type or beam is a type of construction beam which is wider at the support and tapered at its end. Generally, cantilever beams are constructed in Tapered form because the moments are developed at end supports only.

Uses of Tapered Beam

• Tapered beam framing can be used to create offices, retail or other commercial space as well as warehouses up to 120 feet wide.
• Tapered rafter beams are paired with straight wall columns, simplifying the installation of straight interior walls.

14. Prestressed Concrete Beam

In the case of the prestressed concrete beams, the stresses are induced during its construction on site that’s why it is known as prestressed concrete beams. Prestressed concrete beams are more stable can carry higher stresses as compared to conventional concrete beams.

Uses of Prestressed Concrete Beam

• It is now commonly used for floor beams, piles and railways sleepers, as well as structures such as bridges, water tanks, roofs and runways.
• Generally, prestressed concrete is not necessary for columns and walls, however, it can be used economically for tall columns and high retaining walls with high bending stresses.

15. Precast Concrete Beam

Precast concrete beams are also popularly known as cast-in-situ beams which are constructed at the factory as per the required size and specifications.

Precast concrete beams are constructed in the factory itself which is away from the construction site. The construction of the precast concrete beams is done under a controlled environment and supervision.
