Hi all!
When i run a dynamic analysis for a MDOF system, i must use a different mode of programming from the programmation for a SDOF?
For example, for a SDOF for uniform acceleration input at all support nodes, I have to put:
"
set GMdirection 1;
set GMfile "R2.acc" ;
set GMfact 1.0.
"
I ask that because in the example files for a portal (and for all the structures except the cantiliver) there are a different way of programming:
"
set GMdirection 1;
set GMfile "H-e12140" ;
set GMfact 1.5;
source ReadSMDFile.tcl;
set inFile $GMdir/$GMfile.at2
set outFile $GMdir/$GMfile.g3;
ReadSMDFile $inFile $outFile dt.
"
What means the last 4 lines?
they are foundamental?
If i do an analysis without them there a difference from the output files?
Thx!!!

the input motion files are different.
in the first case you have an acceleration-only input file. no changes are needed for it.
in the second case you have file from the PEER database which has a header to it. the readsmd file removes the header and reads what dt is. have a look at the groundmotion files and at the scripts.
