Can we use hidden beams in a flat slab?

Hidden beams can be defined as the beams whose depth is equal to the thickness of the slab. They are hidden in the slab. Hidden beams are generally inserted within the suspended slabs where slab thickness is considerable. The concept of concealed beam originated from flat slab concept.

Why hidden beam is provided in slab?

Hidden beams are usually inserted inside the suspended slabs where slab thickness is considerable. The hidden beam is provided between dining and living spaces right angle to each other. This gives a neat and level ceiling surface that’s good for the look.

Can a beam be created to support an existing slab?

Yes, under certain conditions. 1. If there is a solid/strong contact bet. slab and beam is created by shortcreting or by some means.

Is hidden beam safe?

No Because the depth of beam is needed to decrease the deflection of your beam and safely and economically resist the flexure and shear that developes on the critical sections. So in that respect the beam will carry all the internal actions as far as it is well reinforced and the proper concrete grade is used.

Is slab beam necessary?

It is appropriate when the architectural aesthetic is essential for the interior of the building. It helps to break the extensive slab panel into considerable size. It helps to achieve the desired floor height. It allows brickwork over the slab.

Can you add beams to a flat ceiling?

If you intend to install horizontal beams on a flat ceiling, make sure they won’t compromise headroom. Many local codes limit headroom to a minimum of 7’6” above the floor, so the bottom of your new faux beams should remain above that height.

Is concealed beam necessary?

Concealed beams are popular and form an essential part of modern reinforced concrete framed structures. Lastly, strict and rigid architectural consideration led to the provision of hidden beams. In this manner, the load which might be brick wall will be dealt with and height of the floor will not be compromised.

Can you reinforce a concrete slab?

Structural reinforcement is typically placed in the bottom portion of the slab thickness to increase the slab’s load capacity. Most structural slabs-on-ground have both top and bottom layers of reinforcement for controlling crack-widths and increasing load capacities.

Is hidden beam effective?

Hidden beams are favoured structural elements due to their many inherent features that characterize them; they save on floor height clearance; they also save on formwork, labour and material cost. Moreover, hidden beams form an acceptable aesthetic appearance that does not hinder efficient interior space partitioning.

What is the purpose of hidden beam?

Purpose Of Hidden Beams: To disperse loads on the supporting slab. To break a wide panel of slab to considerable size. To improve architectural aesthetic appearance by providing neat and leveled ceiling surface.

What is the advantage of an I section beam?

The best advantage of a webbed and flanged beam (eg. an I section) is that the material is present where it should be and in the right quantities. This makes the beam more economical and lighter and in turn again making it even more economical. A beam primarily resists bending, shear and torsion.

Why can I see beams in ceiling?

Clearly visible lines on a ceiling could be due to faulty workmanship or substandard materials. The lines probably aren’t the actual joists, which are usually 16 or 24 inches apart. They are probably the joints where the drywall panels meet on specific joists.

What is a hidden beam in construction?

This means one slab structurally rests over the other. Hidden beam is defined as the beam whose depth is equal to the thickness of the slab. They are also known as “ Concealed beam ”. The Hidden beam is a virtual beam that was originated by some one to make use of the BEAM free head room.

Is the depth of hidden beam the same as slab depth?

So, the depth of hidden beam is the same as slab depth as it can be noticed in Figure 2. Concealed beams are popular and form an essential part of modern reinforced concrete framed structures. Lastly, strict and rigid architectural consideration led to the provision of hidden beams.

What are the advantages of hidden beam floor height?

• By providing Hidden Beam floor height can achieved, clears the way for electromechanical duct-work, economical and also aesthetic appearance of the building. • This is more applicable to commercial buildings. • It’s economical as it saves the cost of materials, formwork, and labour.

What is the purpose of a flat slab in construction?

A flat slab is used for two reasons 1 For aesthetics and the other 2 to save head room. In any construction the forces (weight) have to go to the columns and from the columns to the foundation. In the absence of a defined beams which support the slabs we have hidden beams in flat slabs.
