very nice!
.... but you can't use Perform's icons ....

I will not be working on BuildingTcl development for awhile, though. If you'd like to get me the files, please send them to Vesna and she will forward them to me.

silvia

yes, it should.
i don't have an eigen command, but the opensees window gives you the first three periods right after the gravity analysis, or right before the lateral analysis

try first defining the beam, then add the ebf and then go and change the beam's properties, but i'm not sure it will work...

i recommend contacting your system administrator

i'm guessing it worked?

dicche'!

if you look at the examples manual, what i do for the cyclic loading is create a list of displacement increments and then apply them.
i think the easiest thing for you to do is replace that list with a new list of displacement increments that you can calculate from your displacement history.

great!

LOOK AT THE EXAMPLES MANUAL!!!

you have no script for convergence modification in your script.

however, if you fail at the first step, then you have a problem with your model.

ouch,
i'll look into it.
you should be running a batch file (myBuildingTclViewer.bat) because you want to run OpenSeesTk, which then calls the file myBuildingTclViewer.tcl from within OpenSeesTk -- plain OpenSees does not know the Tk commands, such as winfo..

sigma3 has to be less than sigma2 then it goes flat after eps3

mmmm...... i'm not sure now, i remember it doing this....

personally, if i was having convergence problems, i'd check my model!

the histeretic material goes horizontal after eps3.....

you define the behavior of the hinge.
