A hidden beam, also known as a concealed beam, is a structural element used in construction that is not visible in the finished building.
It is a beam that is hidden within the ceiling or floor slab and is designed to support the weight of the structure above it.

- To support the weight of the structure above it for example 4” wall, partition wall, etc.
- To create a clean and unobstructed ceiling or floor surface.
- To allow for larger spans or openings in the building design.
- To improve the aesthetic appeal of the building as well room.
- To maintain structural integrity without compromising design.
The load transfer mechanism in these types of beams is similar to that of conventional beams.
The load transfer mechanism in these types of beams is as follows:
- Load is applied to the structure, such as from a roof or upper floor.
- The load is transferred to the hidden beam, which is embedded inside the floor or ceiling system.
- This beam then distributes the load evenly across their length.
- The load is then transferred from the hidden beam to the supporting beams, columns, or walls through the slab or other structural members.
- Provides structural support for the building without obstructing the design aesthetic.
- Allows for larger spans and openings in the building design.
- It helps to create a clean and unobstructed ceiling or floor surface, which can improve the overall look and feel of the building.
- Can help to reduce construction costs by allowing for the use of fewer visible beams.
- Provides a more open and spacious feel to the building design.
- Designing and installing these types of beams can be more complex and time-consuming than visible beams, which can increase construction costs.
- The location and size of this type of beam can limit the flexibility of the building design.
- These beams are more difficult to inspect and maintain than visible beams, leading to potential issues going unnoticed.
- There is a risk of structural failure if this beam is not designed, installed, or maintained properly.
- Ensure that the design of the beam is correct (as per the structural drawing) and that the structural calculations have been made properly.
- Make sure the formwork is set up correctly to match the shape and size of the beam.
- Use appropriate reinforcing steel and ensure it is placed correctly, following the design specifications.
- Ensure that the concrete is of the appropriate mix and consistency for the project requirements.
- Pour the concrete slowly and steadily to avoid voids or air pockets within the beam.
