Standard Size of Column for building
Hello, friend I am Ramesh. Welcome to this post. If you want to learn about the standard size of column for a building this is the right place. This must know for the civil engineers, architectures, contractors, and overseers.
So today in this article discusses the standard size of columns used in the building structure. You know, in 2021 which type of column is used in the building construction. If you don’t know I will explain in detail about this topic.
So let’s get started:
What is the Column of Building Construction?
First of all, we need to know about the column. The column is the structural member of the Building, which carry the superstructure load and transfer the structural load on the ground soil. A load of the slab, wall, roof slab, celling, and beam is directly transferred by the column into the foundation.
In another word, the building column is a vertical member of a building that is used to transfer all the building load on the foundation.
What is the type of column on the building construction?
The types of columns are divided into different types based. In building construction, different types of columns should be used in 2021. The type of column is categorized on the following based. You can see below the points:
- The column is based on the Shaped.
- According to the type of reinforcement.
- Based on the type of structure loading.
- Based on the slenderness ratio.
- Based on the Using Materials.
Column type based on the shape:
There are different shapes of columns is used in building construction. I have included the most important and most usable column type based on the column shape. Which are the following:
- Rectangular column
- Square Column
- Circular column
This type of column is rectangular in shape. In which the size of the column is 12” X 9”. Which means the length of the column is greater than the width of the column. This type of column is mostly used in building construction due to easily construct an economically good for the building. Easily to install Reinforcement in this type of column.
This is the square shape column. In which the size of the column is 12” X 12” or 9” X 9”. It means the length and weight are equal dimensions. This type of column is also an important and usable column in building construction. This column is economically good for the building due to the easy-to-install reinforcement on the column.
This is the circular shape of the column on the building. This type of column is mostly used in the foundation and front of the building to provide a better design for the building.
This column is constructed in the foundation as a pile foundation. Mostly this column is used in the bridge pillars, and foundation of the building as a pile due to its bending resistance being greater than the other column.
Basically, 4 to 12 reinforcement is used in the column according to the size of the building.
According to the shape of the column, the L-shape, T-shape Y-shape of the column is also used in the construction. L-shape of the column is used in the boundary wall, T shape of the column is used in the bridge and retaining wall of the construction, and Y shape of the column is used in the bridge and flyover construction.
Column type based on the Type of reinforcement
Different type of reinforcement is used in building construction. So column also different type of reinforcement. I have included some type of column according to the type of reinforcement:
- Tied column
- Spiral column
- Composite column
The tied column may be a column during which the longitudinal reinforcement is tied alongside separate smaller diameter transverse bars which also are referred to as ties at the special interval alongside the column height.
Spiral columns are cylindrical within the shape with the continual helical bars which are wrapped around the column. The reinforcement which is employed within the spinal column is additionally referred to as helical reinforcement or spiral reinforcement. The Spiral reinforcement helps to support within the transverse direction.
Composite columns are constructed using various combinations of steel and concrete in an effort to utilize the beneficial properties of every material. The composite column is a combination of different types of steel and concrete. This is the mix of steel with longitudinal direction or spiral direction.
Column type based on the loading of structural
- Axially loaded column
- Eccentrically loaded column
Axially loaded column
In this type of column, the resultant load coincides with the centroid of the column cross-section, which is called axially loaded or concentrically loaded column.
Eccentrically loaded column
In this type of column, the resultant of load does not coincide with the centroid of the column cross-section, which is called an eccentrically loaded column.
Type of column based on the slenderness ratio
- Short column
- Long column
The ratio of the effective length of the column to its least lateral dimension is less than 12 is called a short column. The effective length is bottom to the lateral dimensions of the column. This type of column is failing due to shearing. This type of column is better than the long column.
The ratio of the effective length of the column to its least lateral dimension is more than 12 is called the long column. This type of column is failing due to buckling. It is not a better type of column than the short column.
Types of columns based on using materials:
- Steel column= in the column the steel is used then it is called steel column.
- Timber column= in the column the timber is used then it is called timber column.
- Stone column= in the column the stone is used then it is called a stone column.
- Block column= in the column the block is used then it is called block column.
- Reinforced concrete column= in the column the reinforced concrete is used then it is called a reinforced concrete column.
Standard Size of Column in construction
So, guys the standard size of column is not fixed on the construction. The size of the column depends on the types of the column, using materials, and structure of construction. In the different types of construction use a different type of column so that there are different sizes of the column is used on the construction.
But today in this post I will discuss the basic and most used size of column depending upon the structure and type of column. Stat tuned till the end:
In this period of time, most of the RCC column is used in construction. The different type of techniques is used in the construction. The different types of construction used different ratios of mortar. So the size of the column is directly concerned with the ratio of mortar. I will discuss all the size of the column is For the RCC column.
Generally, in building construction 12” X 12” and 12” X 9” size column is used in the present period of time. But this size depends upon the story of the building and the grade of concrete.
Followings are the Standard Size of Column Table which depends on the story of building and grade of concrete;
Table for Standard size of column:
For one storey building structure, the standard size of the column should not less than 9” X 9”.
In the 10 storey building
1 to 10 storey the standard size of the column is 27” X 27”.
In the 20 storey building
1 to 7 storey the standard size of the column is 30” X 30”
8 to 14 storey the standard size of the column is 23” X 23”.
15 to 20 storey the standard size of the column is 18” X 18”.
In the 30 story building
1 to 10 storey the standard size of the column is 32” X 32”
11 to 20 storey the standard size of the column is 26” X 26”.
21 to 30 storey the standard size of the column is 18” X 18”.
Basically, the structure of the residential building must be constructed in a 2 to 4 story building structure. In this type of structure, the mist has 12” X 12” and 12” X 9” sizes of the column.
Distance between two columns
The distance between two columns has same in the all situations on the construction. But the distance of the column is affected by the size of the column. If the column size has 9” X 9”, the distance between two columns from the center to the center must not be greater than 14’ feet.
While in high of the building is more than 4 stories, the center to center distance between two columns shouldn’t be greater than 23’ feet.
The size of the column must be increased due to the following points:
The height of the structure also affects the dimension of the column if height increases the dimension are going to be more while low in rising building the dimension of the columns are going below.
If the space between two columns increases the dimension of columns also will be an increase
The distance between two columns and the height of the column is directly proportional to the dimension of height.
The standard size of column in a 2 to 4 story building has 12” X 12” or 12’ X 9”. It is the basic size of the column. The size of the column is affected by the type of column, using materials, and structure of construction. The distance between the two columns must not exceed 14’ feet and must not be less than 6’ in the residential building.
