Standard Size Of Column

What Is The Standard Size Of Column

What Is The Standard Size Of Column

The Column has not fixed size. The column’s size depends on the different aspects such as loads on column, material used in column etc. According to these aspects the size of the column should be assumed or accepted as well as after that verification for safety is needed.

What Is The Standard Size Of Column

There are different ( Types of Columns ) such as RCC Columns, long column. Short column, timber columns & tied column etc. now a days, RCC column are mostly use in the structures because it is economical & also bear more load easily.in this article, the size of the RCC columns will be discussed.

The size of the column should not be less than 9” x 9” inches; & for 1 storey building Concrete mix will be M15 [1:2:4].

The size of the column 9” x 9” inches are to be use in one or Two storey structure. For high strength in one or Two storey building the M20 (1:1.5:3) concrete mix will use. While normally M15 concrete mix (1:2:4) ratio is better to use. the size of the column should not be not less than or more than 12” x 9” inches.

Distance between Columns.

The center distance between 2 Columns must be same. In all situations, prepare a layout for the column on a grid. the center 2 center distance between 2 columns with size 9”x 9” inches must not be greater than four meter. While in high rise building the center 2 center distance between 2 columns should not be more than seven meter. It should be less than seven meter.

The size of the column must be increase because of these aspects that is given below.

  • If the distance between 2 columns is increase the dimension of the columns will also be increase
  • The height of the structure also affects the dimension of the column if height is increases the dimension will be more while low in rise building the dimension of the columns will be low.
  • The distance between 2 columns and height of the column is directly proportional to the dimension of height.

Size of Column.

The size of the Column can be assumed by the table that is given below.

S.No

Structure

Number of Storey

Column Size (mm)

1

10 storey building

1 to 10

700 x 700

2

20 storey building

1 to 7

750 x 750

8 to 14

600 x 600

15 to 20

450 x 450

3

30 storey building

1 to 10

800 x 800

11 to 20

650 x 650

21 to 30

470 x 470

For the 10 storey building the size of the column will be 700 x 700 mm. while for the 20 storey building the size of the column for the 1st seven (1 to 7) storey the dimension of the column will be 750 x 750 mm and after 7 to fourteen (8 to 14) for 20 storey building the size of the column will be 600 x 600 mm while for 15 to 20 storey the dimension of the column will be 450 x 450 mm.

Alignment of column

The grid is prepared in Survey of placing the columns. This grid helps to avoid the errors as well as placing of the columns could be implement suitably also the columns can easily be placed in 2 different manners that that is given below.

  • The straight line can be done by the help of a grid.

  • The Circular or Curvature is used in Circular buildings.

The askew or Irregular arrangement of the columns instead of straight is fully incorrect structural design. Moreover, it must be considered that at the time columns are raised, beams are set or joining the columns. Moreover, the askew or Irregular arrangement of create different problems that is given below.

  • Load is transfer Irregularly which results in failure of the structure.

  • Problems is caused in construction of the walls.

  • Problems is caused in setting of the beams.

  • Problem is caused to extend columns in the next slab
