AAT demands a rank in jee advanced.Isnt it?

Yes, only JEE Advanced qualify students can appear for AAT exam.

But B.Arch students cannot give Jee Mains Advance

None Yes barch students cant write advance so how can they appear aat exam plz tell me with out qualifying advance im getting confused

Sayantani Banerejee Why not? If B.Arch students want to take admission in an IIT then they have to give JEE MAINS & ADVANCED and qualify in both of them in order to be eligible to give AAT.

None Yes, and for that you need to give JEE Mains Paper-1 (i.e B.Tech)

So,

Conclusion:- You need to give JEE Mains Paper-1 (B.Tech), you need to give JEE Mains Paper-2(B.Arch), qualify in both(atleast in PAPER-1, in paper-2 you need to qualify or not that I don't know) and finally qualify in JEE ADVANCED and give AAT and qualify in it... That's how you will get an admission in B.Arch course in IIT. (IIT KHARAGPUR or IIT ROORKEE because only these two IITs offer B.Arch courses)
