Introduction of Beam and Their Bending Moment

A beam is a linear structural element that resists loads applied perpendicular to the longitudinal axis of the beam. Beams are traditionally described as either cantilevers or simple supports carrying a uniform load. However, more advanced beam theory considers more complicated supports such as roller or pinned supports. In addition, beams are often compounded of other materials such as reinforced concrete or steel.

Beams can be classified by their profile (shape of cross-section), their length, and their material. The most common type of beam is the I-beam, which gets its name from its resemblance to the letter “I”.

Beams are subject to loads that can cause them to bend. The amount of bending that a beam undergoes is related to

Types of Beam and Their Bending Moment

  • There are various types of beam used in construction
  • The different types are:

    1

  • Cantilever beam
    2
  • Simple beam
    3
  • Fixed beam
    4./ Suspended beam

    The bending moment of a beam is the moment when the force acting on the beam is perpendicular to the axis of the beam

  • The force is usually applied at the ends of the beam
  • The bending moment is calculated by multiplying the applied force by the distance from the fulcrum to the point where the force is applied.

Types of Beam According to Support Condition

  • Beams are traditionally classified according to their support conditions
  • The different types of beams include:

    1

  • Simply supported – A simply supported beam is one that is supported at each end
  • This is the most common type of beam.

    2

  • Fixed – A fixed beam is one that is supported at both ends and cannot move.

    3

  • Cantilever – A cantilever beam is one that is supported at one end and free at the other.

    4

  • Suspended – A suspended beam is one that is supported from below and hangs freely.

Types of Beam According to Function and Position

  • There are two types of beams, based on their function: Support beams and load-bearing beams
  • Support beams are used to hold up roofs, floors, and ceilings
  • Load-bearing beams are used to support the weight of structures above them.

    Beams can also be classified based on their position: Interior beams are located inside buildings, while exterior beams are located outside.

Types of Beam According to Geometry and Shape

  • The most common types of beams used in construction are:

    1

  • Sidewinder Beam: Sidewinder beams are long, slender beams that are typically used in horizontal applications
  • Sidewinder beams are less likely to bend or deflect under load than other types of beams.

    2

  • H-Beam: H-beams are strong, wide beams that are typically used in vertical applications
  • H-beams are less likely to twist or sag under load than other types of beams.

    3

  • I-Beam: I-beams are lightweight, strong beams that are typically used in horizontal applications
  • I-beams are less likely to bend or deflect under load than other types of beams.

    4

  • Box Beam: Box beams are strong, rectangular beams that are typically used in horizontal or vertical applications
  • Box beams are less likely to twist or sag under load than other types of beams.

    5

  • Pipe Beam: Pipe beams are cylindrical beams that are typically used in horizontal or vertical applications
  • Pipe beams are less likely to bend or deflect under load than other types of beams.

Conclusion

The beam is an amazing tool that has been used for centuries to help humans build some of the most impressive structures in the world. From the Pyramids of Giza to the Golden Gate Bridge, beams have played a vital role in some of humanity’s most impressive feats of engineering. Today, beams are still an important part of the construction industry and are used in a variety of applications. While beams are often thought of as being straight, they can actually be curved as well. Curved beams are known as bending moment beams and are used when there is a need for additional strength or support. Bending moment beams are an important part of many structures and can be found in a variety of settings ranging from bridges to buildings.
