Yes, Plain and Multisupport patterns can be used together. Multisupport can use any imposed displacement, velocity, or acceleration.
This is part of my code:
set xDamp 0.05;
set nEigenI 1;
set nEigenJ 2;
set lambdaN [eigen [expr $nEigenJ]];
set lambdaI [lindex $lambdaN [expr $nEigenI-1]];
set lambdaJ [lindex $lambdaN [expr $nEigenJ-1]];
set omegaI [expr pow($lambdaI,0.5)];
set omegaJ [expr pow($lambdaJ,0.5)];
set alphaM [expr $xDamp*(2*$omegaI*$omegaJ)/($omegaI+$omegaJ)];
set betaKcurr [expr 2.*$xDamp/($omegaI+$omegaJ)];
rayleigh $alphaM $betaKcurr 0 0
timeSeries Path 1 -fileTime 0.16hz-2m-time.txt -filePath 0.16hz-2m-power.txt
pattern Plain 1 1 {
load 196 1 0 0 0 0 0
load 197 1 0 0 0 0 0}
puts $alphaM
puts $betaKcurr
set iGMfile "Landers";
set iGMfact "1";
set dt 0.005;
set dispSeries1 "Series -dt $dt -filePath $iGMfile -factor $iGMfact";
set iGMfile "Landers ";
set iGMfact "1";
set dt 0.005;
set dispSeries2 "Series -dt $dt -filePath $iGMfile -factor $iGMfact";
pattern MultiSupport 1 {
groundMotion 1 Plain -disp $dispSeries1
imposedMotion 260 1 1
}
pattern MultiSupport 2 {
groundMotion 2 Plain -disp $dispSeries2
imposedMotion 261 1 2
}
And then say error:
domain::addloadpattern——cannot add as loadPAttern with taglalready exists in model
warning:could nod add load pattern to the domain Multisupportpattern
Can you find wrong with my code?
I have one more question:、
Multisupport Can only added to fix point?
the two question :I want to apply a time force and a seismic load to a model, and then do a dynamic analysis. this why i want use Plain and Multisupport patterns together
How do I operate
can i gei your wechat this is my wechat lq2788538
