hi
i will share a complete script with you all which is single run an perform an adaptive pushover procedure using opensees and tcl features.

HI THIS THE WHOLE SCRIPT . DO YOU THINK THAT THE LOAD PATTERN CHANGE AFTER EACH ANALYZE STEP USING THE LOOP AT THE END OF THE SCRIPT wipe set dataDir Data file mkdir $dataDir model basic -ndm 2 -ndf 3 node 1 0.0 0.0 node 2 0.0 3.96 node 3 0.0 7.92 node 4 0.0 11.88 node 5 9.15 0.0 node 6 9.15 3.96 no...

ok thank you i changed the font in txt file and it worked i have another problem when i use a loop for analysing the structure to change the loadpattern after each analyze step like the below opensees cant converge but when i do not remove the loadpattern there would be no error warning what do you ...

hi dr silvia
what do you mean by that?

and also save command doesnt work
i used for example
save 2
but tcl doesnt recognize the cmmand and print invalid commad

hi
i want to change the loadpattern after eache eigen command
so i used a loop with while command . but it doesnt work
how can i remove load pattern and substitute it with a new one
i used
remove loadpattern $tag
but it doesnt work

superman,
thank you
i am trying to use tcl to update th loadvector
and i think we can do it . i just want to know how could we define matrices in tcl from the eigen vectors after each analyze step and do some mathematical operation on matrices

strep thank you very much that worked also we can use the following command: dos('opensees.exe filename.tcl') but after the analyze it close the opensees command window. let me explain if you run opensees for example a pusover analysis and (analyze 1) it will save just one step result with the recor...

i have to do some process in matlab on eigen vetors after each analysis step and then update the load vetor .i mean i nead updated eigen vectors. but in opensees it doesnt update eigen vector after each analyze step. maybe it is possible if i run eigen command after each analyze step by using a loop...

dear dr silvia
i run opensees with matlab using 'winopen' command; but i dont know how to source tcl files and run the analysis. it jus open the opensees window;
do you haveany idea ?

hi dr silvia
i am here again to ask you lots of other questions
i searched every where in examples and forum to find any example for performing adaptive pushover procedure but didnt find anything
could you please help me dr

of course opensees is a good teacher dr
i will be back very soon with lots of other questions
best regards

[quote="silvia"]ouchy, that's a tough one. i recommend you first do a moment-curvature analysis on all your sections -- easy to say now.[/quote] yes but i really didnt think of that at all i found it by chance but this mistake compelled me to read and try more an more and learn alot during...

dear dr silvia
it was really silly
i used box section in my model and used fiber section to model that but i didnt notice to the sequence of entering the i j k l vertexes of ''Quadrilateral Patch Command''.
but finally i found the mistake
tanx again dr

hi jwieser first of all i suggest you to read examples very carefully lots of your problem solve there. anyway i used pinned conection in sac 20 and also i used simple connection for base connection of sac 9 and sac20 you can use ''equalDOF'' comand to do that first read the manual but this is the e...

hi dr silvia
i solved all my problems
and i wanted to thank you
you helped me so much
tanx again
