What is the size of column for G 2 storey house?

Column size for 2 storey (G+1) building:- For this general thumb rule, we will assume a structure of G+1 (2 storey) residential building, using standard 5″ walls, size of an RCC column should be 9”x 12” (230mm x 300mm) with 6 bars of 12mm Fe500 Steel with m20 grade of concrete and stirrups of T8@6″C/C.

Are 9 x 12 RCC columns safe for g+1 floors?

This setup of 9″ x 12″ RCC columns is safe for G+1 Floors. There are a lot of other considerations, but this is just a thumb rule. For the above column setup, a span of up to 5 meters is quite safe. One can use beams of size 9″ X 12″ (225 MM x 300MM) with a slab thickness of 5″ (125 MM) cast in M20 concrete for spans up to 5m.

What is the minimum diameter of a 9×9 steel column?

The minimum steel in a 9″ x 9″ column is 4 bars of 12 MM with stirrups of 8 MM steel rings at a distance of 150 MM centre to centre. In a 9″ x 12″ column, I add two more bars, to take the total to 6 bars of 12 MM diameter.

How does the size of the columns depend on the beam?

Contact me. The size of the columns depends on the total load on the columns. There are axial loads and lateral loads. Large beam spans induce bending moment not only in the beams, but also in columns which are pulled by the stresses in the beams.
