Dear All
I have attached details calculations. Please refer it in details, who interested in 139202016 ductility.
Earthquake Combination 6 is govern case for column main steel design.
Data: P = 1631 kN
Mu2 = 80.84 kNm
Mu3 = 33.128 kNm
Shear in minor = 48.89 kN
Shear in major = 42.54 kN
As per IS139202016, Cl.7.2 #8 & Cl.7.5 #10.
Data: P = 1631 kN
Mu2 = 80.84 kNm
Mu3 = 2321 kNm
Shear in minor = 1029 kN
Shear in major = 260 kN
In x direction calculation
P = 1631 kN
Mu2 = 590.8 kNm
Mu3 = 33.128 kNm
Shear in minor = 1029 kN
Shear in major = 260 kN
In x direction calculation
Increase data due to IS 139202016
P= 1631/1631 =0
Mu2 = 590.8/80.84 = 7.34 times
Mu3 = 2321/33.128 = 70.06 times
Shear in minor = 1029/48.59 = 21.17 times
Shear in major = 260/42.54 = 6.11 times

Hi Prakash,
As per my knowledge, the analysis is same for ductile & non ductile buildings, the forces variation shown above are very high , literally I shocked with this increase in forces as per 139202016. I don't believe this is due to code change, kindly recheck the model.
Regards,
Saikiran Gone.

Dear Saikiran Gone sir
We agreed with your statement that"analysis is same for ductile and non ductile" but after complete of analysis, Design calculation generate this amount of forces. software design output was checked by manual calculation as attached. if you find any mistake please tell us.

Dear Er Siyani,
You have taken hst = 4.5/2 in your calculation. Is this because the column is terminated at this level?

Yes, sir
Column is terminated at basement slab level

Till date we didn't receive any expert reply with same solution or logic.
please reply of attached photo why this building was not collapse even we tried to collapse row of column.
