Dear mmasoudi
can you show us your recorder code please?
and please explain your beam modelling.

Thank you for your kindly answers dear vesna.

I wish bests for you!

Dear Vesna I copied recorder command from one of Opensees examples (http://opensees.berkeley.edu/wiki/index.php/OpenSees_Example_2c._Nonlinear_Cantilever_Column:_Inelastic_Uniaxial_Materials_in_Fiber_Section#Introduction) to my code and replaced my element number with example element number (without...

my recorders defined after gravity analysis and before pushover analysis (is it OK? )
Unfortunately my model is too big (22 story). I appreciate you for your kindly answers.
I'll try "remove recorders" command. I hope this command solve my problem!

No. I can't see anything (even time) and file is empty.
Eigenvalue and pushover analysis finished successfully but Can be a error in my fiber section modelling?
I'm so confused dear vesna.

### this part records element 151- this element is a shear wall with Fiber Section and modeled with nonlinearBeamColumn (numIntgrPts: 7)#### recorder Element -file $dataDir/ele151sec1Force.out –time -ele 151 section 1 force; recorder Element -file $dataDir/ele151sec1Defo.out –time -ele 151 section 1...

Dear Vesna
at the end of my file "Wipe all" command exist but my recorder returns a empty file for moment and curvature of a fiber section.
another Recorders (for example: Spring Moment- rotation or Forces) work properly.
Can you help me please?

Hi to All
I modeled my shear walls with fiber section.
I put a Element Recorder to record moment and curvature of a fiber section.
after pushover analyze finished successfully , Recorder command returns a file without any data ( 0 KB).
Can anyone Help me?

Dear mjahmadian
I think Ibarra-Krawinkler material can be used in Steel frame joints. i saw several papers that used this material in steel frames modeling.

hi
I want to use fiber section command but i have one question.

what is difference between this Command:
section fiberSec $id {
patch quadr

and this:
section Fiber $id {
patch quad
?

Thank you very much dear Vesna, it worked. my research includes hysteresis calibration and it's my first time that I'm using bilin material, I hope your help will ease the work I have to do, thanks again.

Hi dear vesna, Could I use your code when I want account damage and degradation of strength for my model? I run your code and see just two cycle, how can I see more cycle with degradation? thank you very much
