Load carry Capacity of the column
Axial load of column will depend upon the % of reinforcement and column size for various mixes and steel.
For steel grade fy 415
CONCRETE GRADE &Axial Load carrying Capacity in KN (P)
M15 ,P= (2.7205 p + 6) b D/1500
M20, P= (2.7005 p + 8) b D/1500
M25 ,P= (2.6805 p + 10) b D/1500
M30, P= (2.6605 p + 12) b D/1500
M35, P= (2.6405 p + 14) b D/1500
M40, P= (2.6205 p + 16) b D/1500

For steel grade fy 500
CONCRETE GRADE &Axial Load carrying Capacity in KN (P)
M15 ,P= (3.29 p + 6) b D/1500
M20, P= (3.27 p + 8) b D/1500
M25, P= (3.25 p + 10) b D/1500
M30, P= (3.23 p + 12) b D/1500
M35, P= (3.21 p + 14) b D/1500
M40, P= (3.19 p + 16) b D/1500
For steel grade fy 550
CONCRETE GRADE& Axial Load carrying Capacity in KN (P)
M15, P= (3.625 p + 6) b D/1500
M20, P= (3.605 p + 8) b D/1500
M25, P= (3.585 p + 10) b D/1500
M30, P= (3.565 p + 12) b D/1500
M35, P= (3.545 p + 14) b D/1500
M40, P= (3.525 p + 16) b D/1500
P is Axial Load Carrying capacity of column in KN.
p is steel in percentage say percentage as 1
b is breadth of column in mm
D is depth of column in mm.
