Reinforcement detailing of Columns from ETABS output

AIM - Reinforcement detailing of columns in Etabs 2018.

The ETABS file for a G+4 building is provided. Run the analysis and design the RCC Moment Resisting Frame. The following challenge deals specifically with two columns at the following grid intersections.

1. 3A
2. 3B

• Provide details of longitudinal reinforcement for the two columns, from foundation to terrace level. Sketch the column cross sectional & elevation details or draft it using autocad software. 
• Show shear reinforcement & lapping details as per special confining reinforcement provision of clause 8.1 of IS 13920 - 2016

Procedure - 

Challenge open in Etab as shown 

Now change it to elevation view

 click on start design / check option to start designing and finish 

design is complete, In order to view the longitudinal and shear reinforcement details click on concrete frame design followed by longitudinal and shear reinforcement details.

Longitudinal Reinforcement 

Shear Reinforcement 

Column reinforcements are drawn in AutoCAD next.

Column 3A:

Max Ast = 7027 mm2

So providing 8 bars of 32mm= 6446 mm2

2 bars of 20mm =628mm2

Also provide 10mm stirrups with 150mm for zone C.

As the width is greater than 300mm confining reinforcement is provided  in both the directions.

Column 2B:

Max Ast = 5046 mm2

So providing 8 bars of 28mm= 4920 mm2

2 bars of 12mm =226mm 2

Also provide 10mm stirrups with 150mm for zone C.

Result - Reinforcement detailing of columns is completed.
