What is Inverted Beam?

A reinforced concrete beam with different types of beam shapes like I beam, T Beam, L beam, etc. The height of this beam is the same as the normal height of a beam. It forms an essential part of modern reinforced concrete framed structures.

Strict and rigid architectural considerations led to the establishment of inverted beams.

Inverted beams are the same as upstanding beams; it is used for headroom clearance.

If there is a restriction on maintaining a certain level of beams due to reasons like aesthetics/maintenance purposes, the level of the beam is increased.

Usage of Inverted Beam:

Inverted Beams are used to spreading the concentrated load of the beam on the slab area, originated from a flat slab concept.

Usage in Buildings:

Inverted beams are inserted over the slab where the slab flat is considerable. Provided as the main beam, gives a neat and level ceiling surface that’s good for the look.

Designing an Inverted Beam:

The design is the same as a conventional beam, with a restricted depth and shouldn’t be greater than the thickness of the slab.

Therefore, increasing the reinforcement ratio and width of the beam is significant to overcome the restriction to a certain degree.

Why to use Inverted Beam:

• Used to disband loads imposed on the slab.
• Allows use of greater span for the slab.
• Serves architectural aesthetic purposes in the building interior.
• To break a wide panel of a slab into substantial size.
• Improve architectural aesthetic appearance by providing neat and levelled ceiling bottom surface.
• Saves floor height clearance.
• Allows construction of brickwork over the slab.

Advantages of Uses of Inverted Beam in construction structure:

The inverted beam has several advantages:

1. Providing inverted beam floor height can be achieved.

2. Clears the way for electromechanical duct-work, and also the aesthetic appearance of the building.

3. Applicable to industrial, commercial buildings.
