Response spectrum
Response spectrum
(OP)
This model seems like a mess, however I'm just trying to verify my base shear through a response spectrum analysis. I've attempted it several times, and at first I was getting a base shear of ~200000kN, then I ended up decreasing that to 80000kN (still ridiculously large), and finally back up to 100000kN. Anyways, I don't know what I'm doing wrong, I've spent all week trying to figure out if my structural weight is off in some areas, and I ended up having a bad feeling about floor #3. Well I couldn't quite figure it out.
Could someone please have a look at my ETABS file to see if they can quickly find the issue?
Thank you, I truly appreciate any effort being made to try to get me out of this growing hole.

I removed them all and obtained a fundamental period around 1.3 sec. To answer you question, my scaling follows: (g*Ie)/(RdRo)
Thanks
