Reinforcement detailing of Columns from ETABS output

Answer:

Aim:

To Providing details of longitudinal reinforcement for the two columns from foundation to terrace level.

Step 1:

1) Open a G+4 Etab file

2) Click the Concrete Frame Design tool

3) Select the Display Design Info option

4) Choose design output as Longitudinal Reinforcement

Step 2:

1) After Selecting the Longitudinal Reinforcement click Elevation View

2) To avoid the confusions click tick mark on ribbon and uncheck beam

Step 3:

1) Now need to calculate the reinforcement details of 3a and 3b

Step 4:

1) For Shear reinforcement, Click the Concrete frame design tool

2) Choose Shear Reinforcing

3) Click apply and ok

Step 5:

1) After selecting the Shear reinforcement option the shear reinforcement values are obtained at each column.

Step 6:

GRID A:

1) From Base to first floor the maximum Ast is = 7027

2) So we can provide 10nos of 32mm dia bar = 10 x 804

= 8040mm^2

3) From First floor to Terrace the maximum Ast is = 4800

4) So, We can provide 6nos of 32mm dia bar = 6 x 804

= 4824mm^2

GRID B:

1) From Base to Terrace the maximum Ast is = 5046

2) So we can provide 8 nos of 32mm dia bar = 8 x 804

= 6432mm^2

Therefore it can be satisfied entire span.
