People also ask, what should be the minimum distance between two columns?

Thumb rule no. 2 Distance between the columns Try to maintain equal distance between the centres of two columns. Always plan a column layout on a grid. The distance between two columns of size 9”x9” should not be more than 4m centre to centre of column.

Similarly, how do you place columns? 1.1 Positioning and orientation of columns

  1. Columns should preferably be located at (or) near the corners of a building, and at the intersection of beams/walls.
  2. Select the position of columns so as to reduce bending moments in beams.
  3. Avoid larger spans of beams.
  4. Avoid larger centre-to-centre distance between columns.

Additionally, what is the maximum spacing between columns?

There is no limit for distance between columns. If distance is more beam depth will be greater. Generally for residential building 4.5 metre to 6 metre is economical.

What is the standard size of column?
