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.

Beam & Lintel

01

Beam

  • It is required to transfer load from slab to columns/walls.

Lintel

  • As such it is also a beam. It is required to rest the wall above the openings/door/window in a wall.

02

Beam

  • It is a framing member and part of Structural Frame.

Lintel

  • It is normally not a framing member and not a part of Structural Frame.

03

Beam

  • Beam carries load from slab/floor/roof.

Lintel

  • Lintel carries load of wall above the openings/door/window.

04

Beam

  • It may act as a fixed beam or simply supported beam.

Lintel

  • It generally acts as a simply supported beam.

05

Beam

  • Beam is a horizontal member placed parallel to slab.

Lintel

  • Lintel is a horizontal member placed across opening.

06

Beam

  • Its width can be equal or more than the size of wall below.

Lintel

  • Its width is equal to the size of wall below.

07

Beam

  • Beam is normally provided at floor height.

Lintel

  • Lintel is normally provided above the openings.

08

Beam

  • Though it is primarily a structural member it can also be used as decorative architectural element.

Lintel

  • It is mainly a structural member.

09

Beam

  • Steel will depend on so many factor based on structural design. Normally it will have minimum percentage steel as it is a structural member.

Lintel

  • Normally it has nominal steel.

10

Beam

  • Beam is normally casted with slab as a whole.

Lintel

  • Lintel can be casted separately during construction of masonry wall.

11

Beam

  • It has to be casted on site except for precast.

Lintel

  • Casting off site is possible, Precast also can be used.

12

Beam

  • Its cross sectional area is more as compared to lintel.

Lintel

  • Its cross sectional area is less as compared to beam.

13

Beam

  • There may be long span/short span depending upon structural configuration.

Lintel

  • They are basically short span structure.

14

Beam

  • It should not be misunderstood with lintel band.

Lintel

  • It is not required to be designed for horizontal loads but has to be designed for any cantilever chhajjas, pardi, etc. provided.

15

Beam

  • It can’t be ignored.

Lintel

  • Most of the time neglected and not provided and hence leads to diagonal crack at openings.
