Also, in the Response Spectrum analysis, under Analysis Settings, do not add damping under Damping Controls because Damping of 0.04 was already specified as Q=12.5 when the SRS was computed. Where you have 2e-2 highlighted, set that to 0, otherwise you will be doubling up the damping.
Why did you request Damping of 2e-2 in the Response Spectrum but requested Damping of 4e-2 in Transient Structural? Was that just a mistake? Keep the Damping of 4e-2 in Transient, since that is what I used to build the SRS, but type in 90 Hz instead of 1 Hz because that is closer to the peak acceleration in the SRS.
