A stub column may be defined as a type of column whose length is very small And not attached to footing, made over the beam or slab to transmit the load on the primary beam .
A stub column is a non-structural kind of column and the height of a stub column is very smaller.
The stub column does not contain any footing or pedestal like a standard column. Because it’s beginning or you can say it is made over the beam or slab to take the additional load that serves over it.
The stub column acts as a point load for the primary beam.
1. Uses
The applications of stub columns are as follows:
a. A stub column is delivered to transmit loads from a beam to the footing in case of strap footing.
b. It improves the stiffness of a building.
c. It makes symmetry in geometry and load distribution in a building.
For example, when a room’s span is better or, in the case of the geometry of different floors is not symmetrical.
d. It can be employed to enhance the aesthetic view of a building.
e. A stub column may be operated to reduce the deflection of the beam in the matter of long-span beams.
f. It assists with the safe and dependable share of loads from one beam to another.
2. Advantages
The advantages of these columns are as follows:
a. Helps transfer loads.
b. Improves the stiffness of a building.
c. Creates geometrical symmetry in unsymmetrical floors.
d. Improves the aesthetics of a building.
e. Reduces deflection.
3. Disadvantages
It raises the shear force in a beam on which it is grounded, and the beam may collapse in shear.
So, the beam’s cross-section should be raised, which may be uneconomical in certain cases.
4. Difference Between Stub Column and Floating Column
The difference between the stub column and the floating column is as follows:
| Stub Column | Floating Column | |
|---|---|---|
| It is a column that is not directly attached to the footing and is made between only one floor. | A floating Column is a column that is not directly attached to footing and is made on a building of more than one floor. | |
| The length is very small. | The length is more. | |
| It begins and ends on One floor. | Floating columns start from one floor and go up to the height of the building that is up to the top floor of the building. | |
| It is grounded on a beam or slab. | Floating column grounded on a primary beam or slab. | |
| It works as a point load on the beam. | The floating column also works as a point load on the beam. |
