## Difference Between Beam & Lintel in Structural System

Beam & Lintel both are flexural members and parts of structural system and basically horizontal members but there is a vast difference in its structural behavior and load carrying mechanism.

### Lintel

• It is required to transfer load from slab to columns/walls.
• As such it is also a beam. It is required to rest the wall above the openings/door/window in a wall.
• It is a framing member and part of Structural Frame.
• It is normally not a framing member and not a part of Structural Frame.
• Beam carries load from slab/floor/roof.
• Lintel carries load of wall above the openings/door/window.
• It may act as a fixed beam or simply supported beam.
• It generally acts as a simply supported beam.
• Beam is a horizontal member placed parallel to slab.
• Lintel is a horizontal member placed across opening.
• Its width can be equal or more than the size of wall below.
• Its width is equal to the size of wall below.
• Beam is normally provided at floor height.
• Lintel is normally provided above the openings.
• Though it is primarily a structural member it can also be used as a decorative architectural element.
• It is mainly a structural member.

##### Difference Between RCC Framed Structure and Load Bearing Structre?
• Steel will depend on so many factor based on structural design. Normally it will have minimum percentage steel as it is a structural member.
• Normally it has nominal steel.
• Beam is normally casted with slab as a whole.
• Lintel can be casted separately during construction of masonry wall.
• It has to be casted on site except for precast.
• Casting off-site is possible, Precast also can be used.
• Its cross-sectional area is more as compared to the lintel.
• Its cross-sectional area is less as compared to the beam.
• There may be long span/short span depending upon structural configuration.
• They are basically short span structure.
• It should not be misunderstood with lintel band.
• It is not required to be designed for horizontal loads but has to be designed for any cantilever chhajjas, pardi, etc. provided.

• It can’t be ignored.
• Most of the time neglected and not provided and hence leads to diagonal crack at openings.
