remove elements command

Post by jackmil »

dear vesna
hello
thank u for ur attention;
can i use the remove command like this for ElementS?

set eleList "10006 11006 12006 13006"
evel remove element $eleList ?

for removing a brace that built ten segments,do i have to remove all of the segments to cansel of barce action? or there is another way to do this easier? wasnt there any problem for example deleting elements for convergence problem?

not at the moment. i should and will make the change though. don't forget you must also remove the dangling nodes (again 1 by 1)

dear vesna
i really need your help . . .
i would remove all the bracing segments and their dunglin nodes, but during the analysis, when model reached its limitation by using eleResponse limit state and removed their element and related nodes , it faced with some errors. i think that i should apply some other commands that i dont know them.
does the Opensees understand when the bracing segments removed,stiffnes matrix of model must be changed or updated?
do i remove the recorder with respect to the bracing segments too?

remove the recorders. OpenSees knows the stiffness changes.
