Thank you Vesna, but I still don't understand how I can retrieve the maximum moment. It occurs, indeed, at different time for different analises and its value changes, therefore I would need for a command to find it automatically. Something like set maxmoment [expr max($moment)] where moment is defi...

Hi Vesna and thank you for your time. Probably I didn't explain well what I need to do and I'm sorry about it. It's a cyclic moment-curvature analysis. There are 4 cycles at the same maximum curvature. I want that at the end of the positive fourth cycle the moment is equal to 0.8Mmax. What I am doin...

Thank you Vesna, I managed to do what you suggested me. But I still cannot do what I want to do. I mean, is it possible to find the maximum moment within the list? I am thinking about an expression like the following: set eleForces [eleResponse $eleTag force] set moment [lindex $eleForces 2] set max...

Hi Vesna, thank you for your reply. Nevertheless, I am not sure I have understood how to use the eleResponse command for a node. My recorder is: recorder Node -file Moment_curvature.out -time -node 1002 -dof 3 disp; # output moment (col 1) & curvature (col 2) so I think I should write something ...

Hi to everyone, I am performing analyses on sections in OpenSees with a cyclic analysis. For a certain section the analisys ends when the moment at the fourth cycle is equal to 80% of the maximum moment. What I do is to put a curvature, look at the output in Excel, then change the maximum curvature ...

Thank you!!

Hi Vesna,

did you take a look at my script?
I tried to use ElasticPP or the Hysteretic material insted of Steel01 but I have the same problem...

Thank you Vesna! My script: # [L]=[mm] [F]=[N] model BasicBuilder -ndm 2 -ndf 3 file mkdir Data; #---geometric parameters-------- set al 300.; # section height set la 300.; # section lenght set cf 39.; # concrete cover (respect to rebars) #------------------------------- # ---material properties----...

Hi everyone, I am performing some moment curvature analysis but I have a problem with Steel01. I have put fy=400 MPa but sometimes, after the yielding, tension loss occurs and I believe I cannot read the correct value of curvature. May someone explain me why? This is a segment of what I obtain if I ...

Hi everyone, I am trying to perform some Moment-Curvature Analysis in OpenSees. If I use the Concrete01 material for the confined concrete, the program performs the analysis correctly, but when I use the Concrete04 or the ConfinedConcrete01 I got the message "WARNING: CTestEnergyIncr - failed t...

Hi Zlatko, thank you for your reply. I did what you said but my record is empty and I do not understand why (error in loading??). Here it is my .tcl file, I would really appreciate if you can test it and help me. Thank you. Marco model BasicBuilder -ndm 2 -ndf 3 file mkdir Data; #---geometric parame...

Hi everyone, I want to check the material I am using for an analysis so I want to display the backbone curve of the material before the analysis. Is there a way I can do it? Moreover if at the end of the analysis (moment-curvature) I want to plot the Moment-curvature diagram, it appears just for a s...

I moved up the part of the analysis from "global LunitTXT..."; in this way I can solve the error regarding "fmt1" but the analysis does not converge yet and the message "WARNING SuperLU::solve(void)- Error 1 returned in factorization dgstrf()" is still there!

Hi to everyone, I am trying to do some moment-curvature analyses but I have a problem with the ConfinedConceret01 material. If I use, i.e., the Concrete01 material for the confined core the analysis is correct and I obtain what I expect. If I use, instead, the ConfinedConcrete01 for the confined cor...
