What is the Actual Function of the Practical Column?

In building construction, especially in residential and light-rise buildings, you may often hear the term "practical columns." Although they are not as large as main columns, practical columns play a crucial role in maintaining the strength and stability of walls.

So, what exactly is the function of practical columns, and why should they not be overlooked?

What Are Practical Columns?
Practical columns are additional vertical structures built between brick walls, usually spaced 3–4 meters apart. They are smaller than main columns and serve to complement the building's structural system, especially in wall areas.

Typically, practical columns use 8–10 mm diameter reinforcing steel with cross-sectional dimensions of 10x10 cm or 12x12 cm, depending on the needs.

Main Functions of Practical Columns
1. Binding Brick Walls for Greater Stability
The primary function of practical columns is to bind brick walls, preventing them from cracking or collapsing due to overhead pressure or horizontal forces such as wind.

2. Preventing Structural Cracks in Walls
Practical columns work to resist shifting or changes in wall position, thus preventing long cracks that can occur with conventional brickwork.

3. Increase Building Rigidity
In multi-story or elongated buildings, practical columns help distribute loads evenly, increase structural rigidity, and minimize deformation.

4. Increase Safety in Earthquake-Prone Areas
Practical columns are also part of an earthquake-resistant structural system. These columns prevent walls from collapsing immediately when the building experiences vibrations or ground shifts.

Are Practical Columns Mandatory?
Although not a primary element like structural columns, the presence of practical columns is highly recommended, especially if:

The building's walls are quite long (more than 3 meters)

The building is located in an earthquake-prone area

Using lightweight bricks or Hebel (hebel concrete)

Want long-term crack-free walls
