Reinforcement detailing of Columns from ETABS output
ANS:
The maximum Asc for the column 3A to be considered as per the Etabs design is.
The height of the longitudinal reinforcement of the column from the base to tarrace.
That is the height of 7027,6926,4800,4213,3525=7027mm2 is provided for the column.
The reinforcement detailing for the column is shown in below.
Total no of longitudinal bars=(total Asc of column )/(Asc of the any dia bar per meter)
Provide 12 bars of 28mm diameter for the column=615.752*12=7389mm2>7027mm2 hence ok.
The maximum Asc for the column 3B to be considered as per the Etabs design is.
The height of the longitudinal reinforcement of the column from the base to tarrace.
That is the height of 4218,4942,5046,4858,4902=5046mm2 is provided for the column.
The reinforcement detailing for the column is shown in below.
Total no of longitudinal bars=(total Asc of column )/(Asc of the any dia bar per meter)
Provide 8 bars of 25mm diameter for the column=490.87*8=3927mm2
Provide 4 bars of 20mm diameter for the column=314.16*4=1256.64mm2.
Total=3927+1257=5180mm2>5046mm2 hence ok
