Spectrum Generator: ASCE 7 - 01/04/13 05:17 PM
I have generated a seismic spectrum with the DLF/Spectrum Generator in CII using the appropriate factors.
When I go through ASCE 10-7 by hand using the same factors and generate a spectrum, I expected this to be the same but it was very different.
I'm looking at the peak accelerations; from the ASCE7 in CII the peak is 0.39g, using the code to calculate the spectrum by hand the peak is 0.85g (this is the Sds value).
Can someone help explain why there is a difference and how the spectrum is generated with the DLF generator. I have been looking into this for a few hours and have read the 1994 newsletter, but am still a bit lost.
Thanks in advance,
Louie
