Reinforcement detailing of Columns from ETABS output
AIM:
To provide the details of longitudinal reinforcement for the two columns (3A & 3B), from foundation to terrace level.
The details of shear reinforcement as per special confining reinforcement provision of clause 8.1 of IS 13920 - 2016.
Procedure:
Step1: First Challenge open it in the etabs 2018, as shown below.
Step2: Next we need to keep the model in the elevation view, as shown below.
Step3: Next we have to start the design by selecting the 'Start Design/Check' option, then we have to wait till the design completes, as shown below.
Step4:
When the design completes, the details of the longitudinal reinforcement will be visible, as shown below.
Step5: Next we need to select the 'Display Design Info' option and then select shear reinforcement in the design output and click on the ok button.
Now the shear reinforcemnt details will be visible, as shown below.
Step6: Now the details of shear reinforcement will be visible, as shown below.
Step7:
Here for the column-7 (3A intersection), we take size of column is 450mmX650mm.
The maximum Ast for the column-7 is 7027mm
Now we provide 16 bars with 18mm dia(16-184), shown below.
And we provide size of the stirup as 10mm. for Zone A we provide 100mm spacing and for Zone C we provide 150mm spacing, as shown in the below figure.
And the details of shear reinforcement are provided as per special confining reinforcement provision of clause 8.1 of IS 13920 - 2016
Step8:
Here for the column-8 (3B intersection), we take size of column is 450mmX650mm.
The maximum Ast for the column-8 is 5046mm²
Now we provide 16 bars with 20mm dia (16-20%), as shown below.
And we provide size of the stirup as 10mm, for Zone A we provide 100mm spacing and for Zone C we provide 150mm spacing, as shown in the below figure.
And the details of shear reinforcement are provided as per special confining reinforcement provision of clause 8.1 of IS 13920 - 2016.
RESULT:
Finally, we provided the details of longitudinal reinforcement for the two columns (3A & 3B) successfully, from foundation to terrace level.
Provided the details of shear reinforcement as per special confining reinforcement provision of clause 8.1 of IS 13920 - 2016.
And also provided the column cross sectional & elevation details.
