Thanks for your attention!
I have got stuck up generating spectrum in Staad using EC8 2004
Syntax: SPECTRUM CQC EURO 2004 ELASTIC RS1 X 1 Z 0.3 ACC DAMP 0.05 LIN SAVE
SOIL TYPE C ALPHA 0.36 Q 2
when i change the Q factor above from 1 to 2 in EC8 2004 definition, i do not see any change in my spectrum values.
Indeed if i use EC8-1994 definition . i could see the change in the spectra values. Im bit worried , i havent done spectrum analysis in staad pro earlier.
Could someone help me on this? I need spectrum for the following conditions. Soil type:C, Q=2; Elastic Type I Spectra, Ground acceleration =0.36g, X=1,Z=0.3
It would be much helpful if someone gives a try and provides me the spectrum(As per EC-8, part -I), Period vs Acceleration values
Many Thanks in anticipation
