Practical Columns Extending Too Far: What Is the Impact on the Wall?

Practical columns serve to bind, reinforce, and maintain the stability of masonry walls. Therefore, their placement must be carefully planned based on the building's specific conditions.

If the spacing between practical columns is excessive and fails to meet construction requirements, overly long wall sections become more susceptible to movement and cracking. Consider the following potential impacts:

**Increased Susceptibility to Cracking**
Wall sections that are too long without adequate stiffening are more prone to cracking.

Temperature fluctuations, material shrinkage, and structural movement can induce stress within the masonry. Practical columns help subdivide these wall sections, thereby reducing the risk of cracking.

**Reduced Wall Stability**
Practical columns help keep the wall stable and securely tied to the building's structural framework.

If the spacing is too wide, the wall section between columns becomes longer, increasing the need for structural stiffening.

**Increased Susceptibility to Movement**
Masonry walls are not designed to bear all types of structural loads.

If a wall section is excessively long and lacks sufficient stiffening, it becomes more vulnerable to shifting or deformation under certain conditions.

**Higher Risk of Cracking Around Openings**
Doors and windows create discontinuities in the wall surface. If stiffening details around these openings are not properly planned, the surrounding areas become more prone to cracking.

Consequently, the placement of practical columns must be coordinated with the location of openings and other stiffening elements.

**Risk of Damage to Finishes**
Movement or cracking within the masonry can transfer to the plaster and skim coat layers.

This can result in hairline cracks, larger fissures, or finish damage requiring repair.

**More Practical Columns Is Not Necessarily Better**
Simply increasing the number of practical columns without proper planning is not the right solution.

The size, spacing, reinforcement, and connections of practical columns—relative to grade beams (*sloof*), structural beams, and structural columns—must align with the building design.

**What Should Be Considered?** Determining the spacing for practical columns requires consideration of several factors, such as:

The length and height of the wall section.

The type of masonry material (e.g., red brick or lightweight brick/AAC).

The placement of doors and windows.

The number of building stories.

The primary structural system.

Environmental conditions and potential building movement.

The specific construction details employed.

Since every building presents unique conditions, do not determine practical column spacing based solely on general figures or common field practices. Instead, use working drawings and structural calculations as your reference.

Conclusion
Excessive spacing between practical columns can result in a wall section that is insufficiently tied, making it more susceptible to movement and cracking. These issues affect not only the masonry itself but also the plaster layers and wall finishes.

Therefore, practical column spacing must be planned according to the specific conditions and design of the building, rather than being determined by mere estimation.
