Dear readers, you are most welcome. Today we have brought up a new topic which is about what should be the Minimum and maximum distance between two columns. Here we will tell you how this article is important to all of you. We shall also discuss the different types of columns used in building construction. With together Factor controlling the distance between the two RCC columns will be discussed also. So please don’t go anywhere and start reading our article. We will try to give you full knowledge at our level best.
What is column?
A column is a component that bears the load of any structure. It keeps standing itself in a vertical way, and It sends a load of superstructure to the foundation. It can be constructed by using steel, concrete, aggregate, etc.
What are the different types of columns used in building construction?
There are various types of columns are given below.
- Spiral column
- Tied column
- Composite column
- Long column
- Short column
- Circular column
- L shaped column
- T shaped column
- Rectangular or square column
These columns are made of cement which is reinforced. Spiral columns are constructed in a circular way. It prevents axial load failure. When such types of columns are made then rods are used in a twisted way.
You know one thing about this type of column. In all types of structures, around 90% of tied columns are used. This type of column goes upright lengthwise. In the tied column, we use rods with a certain distance and use some pieces of rods as a ring to tie around them.
This column is known for its hardness, strength, and stability. It provides stability to the structure. Composite columns are made by using two materials. Reinforced steel and concrete are used to build this. It has many benefits. As like it prevents form large energy (fire burning). It absorbs heats. Among the steel bars a steel metal that looks like the railway track is used to make this composite column.
Do not confuse yourself by listening to the name of the long column. Although its name long column its load-bearing capacity is not so perfect. Generally, people don’t prefer this type of column in their structure. It bends after giving a heavy load.
The thickness ratio of such type of column should not be more than 45. When we extend the length of this column it loses its load-bearing capacity. If it will happen then your structure can collapse. Sided dimensions of this column must be 12 it is more than enough. It has a very less gyration radius.
This type of column must have an a-sided dimension of less than 12. Short column length is fixed by the less dimension of the column. Such columns can bear more load than long columns. The thickness ratio of this column must be less than 45. The short column has a very much gyration radius.
This type of column is used to give an attractive design to the structure. Circular columns are used to provide elevation to the building. These columns are used in pilling also. Circular columns are earthquake resistant. As they are very strong. In a place where earthquakes take place from time to time. We use the circular column in any structure or building. Because it is very necessary to protect the structure from the jerk of an earthquake. Such a column has a huge capacity for strength and flexibility.
L- shape column
Generally, L-shaped columns use to provide strength to the corner wall of any boundary or structure. These types of columns can casted and constructed easily.
T- shape column
These columns are used in high-rising buildings. These are also seismic-resistant. T shape columns are very strong. It gives us high performance. These are used as side columns in any structure or building. Such types of columns are used in the construction of bridges especially.
Rectangular or Square column
I don’t think that there is a need to tell you anything about this column. Generally, This type of column is used in all types of buildings and structures. Such type of columns installation is very easy. This column has also long durability.
Minimum distances between two RCC columns?
First of all, I want to tell you that there is no fixed rule to build columns. For general structure or building the minimum distance between two columns should be 2.7 m or 3 m.
Maximum distances between two columns?
maximum distances between two columns should be 6 m to 8 m.
But if you are constructing a small structure then the distance between two columns should be 3 m to 4 m. While you are constructing a huge structure the distance between two columns should be 7.5 m to 8 m. Here you will have to notice one thing if the load of the structure is very high then you will have to increase the size of the columns. Distance will be the same or you can change it according to the measurements.
Well, next I am going to tell you more about columns uses.
What should be the maximum distance between two rcc columns for single-storey buildings?
In a single-storey or normal building, the maximum distance between two RCC columns should be 2.7 to 3.5 m or 9 to 10 feet. It is more than enough.
Maximum distance between two RCC columns for G+1, G+2, G+3, and G+4 storey residential buildings?
In a G+1 storey building the maximum distance between two RCC columns should be 3.5 m – 4 m or 11 -13 feet. It is more than enough. If you keep more distance than you will see cracks in the walls after some years.
In G+2, G+3, and G+4 storey buildings, the maximum distance between two RCC columns should be 13 to 15 feet or 4 m to 5m. Sometimes in G+2, G+3, and G+4, these column distances can increase by 22 to 26 feet or 7m to 8m as per need. But in such a situation column size also increased.
Minimum distance between two RCC columns for G+1, G+2, G+3, and G+4, storey residential buildings.
Minimum distance can not be less than 2.7 m between two RCC columns in single-storey or normal buildings as well as G+1, G+2, G+3, and G+4-storey residential buildings. One thing that should note here when you reduce the distance between two columns the number of columns will increase and it will make you extra cost. It will affect your superstructure.

Finally, I have tried my level best to give more and more information about columns. Maximum and minimum Distance between two rcc columns. Types of columns. Distance between two rcc columns in the single storey as well as G+1,+2,+3,+4,+5 buildings. I hope you will be satisfied by reading our article.
