Reinforcement detailing of Columns from ETABS output

Aim - To calculate the reinforcement of the coloumns by the results in the ETABS

Procedure - 

Grid 3A

Londitudinal reinforcement

Wgo the max value of  6926

4 no of 32mm = 3216

8 no of 25mm = 3920

Total 7136

4 no of 32mm and 8 no of 25mm

Shear reinforcement 

8mm rebar of 200mm spacing

750 will satisfy with 720

Grid 3B

Londitudinal reinforcement

W got the max value of  6926

2 no of 32mm = 3920

8 no of 25mm = 3920

Total 5528

2 no of 32mm and 8 no of 25mm

Shear reinforcement 

8mm rebar of 200mm spacing

750 will satisfy with 720

According to IS456 the minimum longitudinal steel should be 2340mm2 but we are providing a lot more excess steel

The maximum shear reinforcement spacing should not exceed 300m but we provided 200 it is satisfied

The lap length should also be 41d we have followed it

Io shoulsd not be less

-larger coloumn dimension

-1/6 clear span dimension or 450mm

We have taken 650

Conifinement bar should not be greater than 

- 1/4 smaller coloumn dimension and 6 times of dia of main bar or 100

We have take the 100mm

The amount of confinement bar should be 169

We've taken 720
