In modern building construction, columns play a crucial role in supporting the structure. However, rectangular or square columns are widely preferred over circular columns. This article highlights 7 reasons why circular columns are not commonly used in house construction.
1. Architectural Appearance
Circular columns protrude out from masonry walls, creating an unaligned surface between the column and the wall. This irregular alignment affects the overall architectural appearance, making the interiors and exteriors look unpleasant.
2. Space Utilization
Rectangular columns fit perfectly with walls, offering better space utilization. On the other hand, circular columns occupy more space, especially at corners, making it difficult to arrange furniture like beds or wardrobes.
3. Door & Window Fixing
Fixing doors and windows at column junctions is much easier with rectangular columns. They allow the full utilization of wall space without obstructing the door or window openings. Circular columns create dead spaces, making installations cumbersome.
4. Structural Orientation
Rectangular columns can be oriented to resist bending moments efficiently. However, circular columns cannot be oriented to optimize load resistance, making them less effective in structural performance.
5. Formwork Cost
Formwork for circular columns requires metallic molds, which are expensive and difficult to fabricate. Conversely, rectangular columns use plywood and battens, which are cheaper and reusable for multiple column sizes.
6. Finishing Work
Plastering and finishing circular columns is more labor-intensive and requires skilled workers. Flat surfaces of rectangular columns are easier to finish, reducing both time and labor costs.
7. Sign Board Installation
Flat surfaces of rectangular columns offer a convenient base for installing signboards and advertisements. Circular columns lack visibility, making them unsuitable for such applications.
Conclusion
Square and rectangular columns dominate house construction due to their better space management, cost-effectiveness, and architectural appeal. Circular columns, though used in certain special cases, are not ideal for residential buildings.
By understanding these key reasons, homeowners and engineers can make informed decisions in their construction projects.
