Reinforcement detailing of Columns from ETABS output

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

Step 1:

1) Open a G+4 ETABS file

2) Run Analysis

3) Click the Concrete Frame Design tool

4) Select the Display Design Info option

5) Choose design output as Longitudinal Reinforcement

Step 2:

1) After Selecting the Longitudinal Reinforcement click Elevation View

2) Check Only Columns In All Storeys

Step 3:

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

2) Click Concrete Frame Design

Step 4:

3)Click Display Design Info and Click Shear Reinforcement

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 16nos of 25mm dia bar = 16 x 490 = 7840mm^2

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

4) So, We can provide 16nos of 20mm dia bar = 16 x 314 = 5024mm^2

GRID B:

1) From Base to Terrace the maximum Ast is = 4902

2) So we can provide 16 nos of 20mm dia bar = 16 x 314 = 5024mm^2

Therefore it can be satisfied entire span.
