Types of beams:

structural design in Madurai; structural designer

There are different types of beams in construction and structural fields. To begin with, the beams are structural element. Firstly, they withstand the shear forces, vertical loads, and bending moments. Secondly, beams carry the loads to walls, foundations, and columns.

In this blog, let us see various types of beams in building construction on the basis of their manner of support, length, cross section shape, and their material.

We classify different types of beams on the basis of conditions below:

  • Support conditions.
  • Cross section shape.
  • Construction material.
  • Equilibrium condition.
  • Geometry.
  • Method of construction and
  • Others.

Support conditions:

Fixed beam:

This type of beams’ support is at its both ends. Since it is fixed beam, it is not to rotate. What is more, the fixed beam has another name ‘a built-in beam’.

Simply supported beam:

Structural Design in Madurai:

Simply supported beams are one of the easiest and simplest structural part. The both ends of these types of beams rest upon support. However, these beams are free to rotate. At one end, the support consists of pinned support. On the other end, it consists of rollers support. Based on the application of load onto them, it sustains bending and shearing.

Cantilever beams:

At one end, Cantilever beams rest. Other end will be free. Yet, the beam gives the load back to the support. Important to realize, Cantilever beams let the creation of balconies, windows, and some bridges.

Continuous beams:

This type of beam has several supports given along its complete length. Moreover, continuous beam has two types. First, we can stretch the beam continuously. Second, we can stretch the beam for some distance. 

Construction materials:

Reinforced concrete beams:

We form this type beam from reinforcement and concrete – cement, sand, and aggregate.

Steel beams:

We form this type beam from steels. Also, we can use in many applications. Steel types – MS, SS, Aluminium, and more.

Timber beam:

Timber beam was used in the past. We construct it from timber. Now its applications and usages are noticeably declining. Furthermore, we use timber beam in hill stations.

Composite beam:

We form this type beam from more than two materials, for example, steel and concrete. And also different valid cross-sections are used in an effective way.

Cross section shapes:

Structural Design in Madurai:

In the first place, we can avail many cross sectional forms of beams. We can use the beams in various parts of structures. Not to mention, we form these types of beams from steel, reinforced concrete, or composite materials.

Rectangular beam:

Rectangular beams are extensively used in reinforced concrete buildings and structures.

T-section beam:

Mostly, we form T-section beam in relation with reinforced concrete slab. Isolated T-section beams are sometimes formed to rise the compression strength of concrete.

In addition, we can form inverted T-beams in accordance with the needs of loading applied.

Structural Designer:

L-section beam:

At the perimeter of the structure, we form L-section beams in relation with reinforced concrete slab.

Steel cross sectional shapes consist of:

There are different steel beams cross sectional shapes. And every cross sectional shapes give greater profits in a given conditions in comparison of other shapes.

In this case, some examples of beam sectional shapes formed from steel: square, circular, rectangular, T-shaped, I-shaped, C-shaped, H-shaped, and tubular.

Structural Designer:

I-section beam:

It has another name – H-section beam.

O-section beam:

We can call O-section beam as Circular beam.

Straight beam:

In general, Straight beams are beams with straight profile. Typically, we use this type beam in construction.

Curved beams:

Curved beams are, in general, beams with curved profile. For example, construction of circular shape and arch shape. In addition, we mainly use it for pergolas and elevation elements.

Tapered beam:

In general, Tapered beams are beams with tapered cross section. We use it for A-roof and Pyramid roof. Commonly, we use it for elevation purpose.
