What is Column in Construction? Types and Importance

Introduction

The columns are structural elements that are responsible for the stability of the structure and bearing the weight of the building. To find out what is column in construction, it is a structure which carries loads safely to the foundation. In this guide, you will learn about construction column basics, the types of columns in construction, and the importance of columns in buildings. Column in civil engineering are an important component of the load bearing structure.

What is a Column in Construction?

A vertical member that connects the upper portion of a structure to the foundation to carry the structural loads. So, what is column in construction ? A construction term that simply means a structural member that supports the building safely. What is the role of column in building construction ? This is also the function of column in the construction of buildings.

Importance of Columns in Building Construction

The importance of columns in buildings is very high because they support slabs, beams, and the overall structure. The importance of columns in structural engineering is that they heighten the stability of the structure and transfer the vertical loads in a secure manner. A building can crack or be unsafe if it lacks proper columns.

Types of Columns in Construction

Based on shape, material, reinforcement, and load behavior, there are different types of columns used in construction

• Square Column is widely used in residences and small structures due to its simplicity and ease of construction.

• Rectangular column, it may be employed in cases where a wall line or space planning requires longer shape.

• Circular Column is frequently used in architecture, decoration and in some open areas.

• RCC Column is most commonly used in buildings due to combining strength of concrete and steel.

• Steel Column is adapted for situations requiring quicker construction and lighter structural framing.

• Composites Column: Steel and Concrete for Enhanced Strength and Performance.

• Tied Column is an RCC column with lateral ties holding the main reinforcement bars.

• Spiral Column reinforced with spiral rebar, and is commonly selected for enhanced confinement.

• Short Column is stronger due to its small height compared to it's size.

• Long Column is taller and narrower, and buckling is a more significant design consideration.

These are the primary building column types and also a part of RCC column types and their uses in modern construction. Another important structural classification, besides short column and long column, is the classification based on height and slenderness.

Classification of Columns Based on Shape and Material

• Shape-based classification has square, rectangular and circular columns.

• Material-based classification includes RCC, steel, composite, timber, and masonry columns.

• Load-based classification axially loaded columns, uniaxially loaded columns, biaxially loaded columns.

It helps to understand the role of load bearing column types and when they are chosen in projects.

RCC Columns vs Steel Columns

• Both steel column vs RCC column have their own advantages and disadvantages.

• RCC column construction of houses as they are durable and have good fire resistance.

• Steel columns are light and quick to assemble, which is beneficial for industrial and business ventures.

• So, when you ask steel column vs RCC column which is better, it depends on cost, speed, type of project, design need, etc.

Factors Affecting Column Design

Many things affect structural column design, including load from slabs and beams, building height, soil condition, earthquake zone, material strength, reinforcement, and column position. These factors decide the final size and reinforcement details of the column.

Common Mistakes to Avoid in Column Construction

Common mistakes such as inadequate reinforcement placement, poor concrete mix, misaligned reinforcement, inadequate cover, or inadequate curing. Even the slightest error in RCC column construction can result in a loss of strength and compromise safety.

Latest Column Design Trends in Modern Construction

The current modern column designs are slimmer columns, anti-earthquake columns, clean columns, and space-saving columns. Circular and rectangular exposed columns are also becoming common in modern architecture.

Conclusion

Knowing what is column in construction is crucial for safe and prudent building practices. A column's role is essential in every project, from load transfer to structural stability. Having information on the types of columns in construction, the importance of columns in buildings construction and the basics of RCC column types will make it easier for homeowners and builders to make decisions.

FAQs

1. What is a column in construction?

A column is a vertical member of the structure that ensures the safe transfer of building loads to its foundation.

2. What are the different types of columns in construction?

They are usually square, rectangular, circular, RCC, steel, composite, tied, spiral, short, and long.

3. Why are columns important in buildings?

They provide safety of structure and load transfer downwards.

4. What is the difference between RCC column and steel column?

The RCC columns are heavier in comparison to the steel columns and are commonly used in houses, while steel columns are lighter and quick to install.

5. What is the function of a column in a structure?

It is primarily used for load transfer and structure support.

6. What are short columns and long columns in construction?

A short column is not so slender, and is more resistant to buckling, whilst a long column is tall and slender.
