calling rSpectrum.dll

[Hyoungsuk Choi]

Hello, I just download rSpectrum.dll which is response spectrum analysis tool in your website. But I can’t call the rSpectrum.dll in Opensees. As you instructed in manual, I put the a line, ‘loadPackage rSpectrum’, however opensees says ‘Invalid command name’. So, could you help me?

rSpectrum was loaded but pFactor does not work properly now…
Memory problem is occuring in Opensees. Please, help me.

Hi Hyoungsuk Choi,
In my response spectral analysis of a bridge, the rSpectrum.dll is included in the same file folder which is automaticlly loaded in the procedure008.tcl. And the settings of the response spectral analysis is as following,
——————–
source procedure008.tcl
………..
set iDirections { {X Y} {Z} } (or set iDirections { {0 1} {0} })
set iSpectra { “RS.txt” “RS.txt” } (or set iSpectra { {“RS.txt”} {“RS.txt”} })
set modes 50
set patternStart 1
set comb 2
set csi 0.05
set directions $iDirections
set spectra $iSpectra
DynWrapper #modes #patternStart #comb #csi #directions #spectra #modelName
———————
But the OpenSees gives the error “Invalid spectra and/or directions lists”. DO you think there is anything wrong in the settings? Could you minding give me some instructions to correct the settings?
Thank you very much!
