how to define the contact between the new and the old concrete?

can OpenSees do optimization analysize?

yes

in my simulation, three load pattern is applied in turn, 1.pattern Plain 101 Linear { eleLoad -ele 221 222 -type -beamUniform -$QdlBeam eleLoad -ele 131 132 133 -type -beamUniform 0 -$QdlCol eleLoad -ele 141 142 143 -type -beamUniform 0 -$QdlCol eleLoad -ele 151 152 153 -type -beamUniform 0 -$QdlCol...

if the load pattern is removed, how could I define the load pattern?

and if the load pattern is removed, Opensees can't converge

how to recorder the force of a node? recorder Node -file $dataDir/RBase.out -time -node 11 12 13 -dof 1 reaction; # support reaction I think that this command can only record the support force. I used the following command : pattern Plain 200 Linear { load 71 1 0 0 0 0 0 }; how could I get the value...

In my test, the gravity load is applied to a 6 story-2 bay frame first, then the static reversed load is applied. last, the point load is applied. the problem is when the point load is applied, it can't converge, whereas this problem didn't occur when the gravity load and the reversed load were appl...

where the code given by fmk should be added in? I added them just after source LibAnalysisStaticParameters.tcl; as: load 71 1 0 0 0 0 0 source LibAnalysisStaticParameters.tcl set time 0.0 load control 0.0 analyze 1 but it didn't work(warning: the load control is an invalid command). I don't know muc...

I have changed as following, but it didn't work:


load 71 1 0 0 0 0 0


set time 0.0
integrator LoadControl 0
analyze 1

if {[$Dincr>0] && [$Dstep>-159.6]} stop


when run it, the warning is: invalid command name "0.21>0"
while executing
"$Dincr>0"

the following is my manuscript. how to change it? I tried,but it didn't work # source in procedures source GeneratePeaks.tcl; # procedure to generate displacement increments for cyclic peaks # characteristics of cyclic analysis set iDmax "1/200 2/200 3/200 4/200 5/200 6/200 7/200 8/200 9/200&qu...

thank you ,fmk! I seeked in the manual ,but can't find setTime or loadControl command, how to use them? I applied the gravity load first ,and then apply the static cyclic load using displacement control, at last , i want to apply a additional load just after the substep of force=0, but in the static...

in static cycle analysis, the last step is corresponding to the displaecment=0, if the next analysis is expected to begin at the step corresponding to the force=0, how to do it?

thank you,dear silvia! then how to define the coordinate of the element?the X,y coordinate have changed after earthquake

dear silvia, I opened rbase.out file with excel, only 8422 rows could be shown, how to resolve this problem?
