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 as given in the question

The details of shear reinforcement as per special confining reinforcement provision of clause 8.1 of IS 13920 - 2016.

Procedure:

open the last challenge diagram as we done

unlock the design to edit

>>click on the design check

now we need to longitudinal reinforcement and shear reinforcement along the column of 3A and 3B

now we need to check for the longitudinal reinforcement details

for that go to view box and deselect all beams floors and walls sp that we can edit only columns

nxt all the columns we get visible

select only 3A and 3B colums

give right click go for the view selected objects only as we got given below

now go to design check>longitudinal reinforcement

now for the shear reinforcement details same as above

design check>shear reinforcement

explanatuion:

column 3A:

longitudinal reinforcement:

assume cloumn size as 450x650

maximum Ast value=12011mm^2

provide 6bars of 32mm dia 4corner and 2 on bothside middle of longer dim of column

2bars of 25mm dia middle of shorter side

shear reinforment :

max Ast value=1265mm^2

provde 8mm dia 100c/c diatance upto 1/4 height of column span and 1/4 from the beam column junction

in the middle span provide 8mm dia 200c/c spcing

this is the same process for all storys

column 3B:

longitudinal reinforcement:

maximum Ast value=13065mm^2

so we can

provide 8bars of 32mm dia 4corner and 4on bothside middle of longer dim of column

2bars of 25mm dia middle of shorter side

shear reinforment :

max Ast value=1302mm^2

provde 8mm dia 100c/c diatance upto 1/4 height of column span and 1/4 from the beam column junction

in the middle span provide 8mm dia 200c/c spcing

this is the same process for all storys
