I used limits on the material strain in both time history and cross-section analysis, and I got difference in the curvature limits between two piers (the one with As ≈ 1.8% and the other with As≈ 3.2%) in the cross-section analysis, but I didn’t get any difference in the curvature limits between the...

Dear Sir, I performed a time history non linear inelastic analysis (using a given ground record) on a 2D frame representing a three-span bridge with two piers fixed at bottom and hinged to the deck at their top; I recorded the moment and the curvature at each pier base. Also, I scaled the ground rec...

yes i have this part of the code and it is as follows: code: while {$ok == 0 && $tCurrent < $tFinal} { set ok [analyze 1 .01] # if the analysis fails try initial tangent iteration if {$ok != 0} { puts "regular newton failed .. lets try an initail stiffness for this step" test NormD...

Here is the convergence script when I run the program. The analysis is completed successfully but I still got nonsense results. CTestNormDispIncr::test() - iteration: 1 current Norm: 0.000253082 (max: 0.01, Norm deltaR: 4.95783e-005) CTestNormDispIncr::test() - iteration: 1 current Norm: 0.000253013...

I checked the recorders; they are the same as the examples manual.

Dear,
I tried to use the latest release of the opensees, also I tried to change the convergence tolerance of the code; but I still have a numerical divergence at the same scale factors. I hope you can help me to solve this problem; I can send my code. Thanks

Thanks for your prompt response
I tried it with the latest release but i still have the same problem.

Hello I performed a time history non linear analysis (using a given ground record) on a 2D frame representing a three-span bridge with two piers fixed at bottom and hinged to the deck at their top. I scaled the records incrementally and for each scale value I recorded the maximum absolute curvature ...

Hello
Can I use MinMax material while I am doing a time history non linear analysis or a pushover analysis on a 2D frame?
Thanks

Dear,
I want to model a CONTINOUS girder connected to column through bearings (only the upper node of column doesn’t carry moment).
how can I model this connection?

Thanks for your prompt response and Sorry for not being clear. The code is the same as the manual including calling the moment curvature procedure. but i got a convergence error when i am trying to target higher ductility mu=70 . lower i attached the whole code .how can i solve that error? code: # D...

Thanks for your prompt response.
This code is the same as the examples manual, but I realized that I got that convergence error while I am trying to target a higher ductility (mu=70).could you help me to solve that error?

Hello I got a convergence error during moment curvature capacity analysis. I‘d like to know why I got that error and what are the possible solutions. Thanks for help [b]Error:[/b] WARNING: CTestNormUnbalance::test() - failed to converge after: 10 iterations ModifiedNewton::solveCurrentStep() -the Co...

Dear , Sorry my question wasn’t clear The problem is: 1)I am using the minmax material and I want to know what do min and max words represent in this code. uniaxialMaterial MinMax 4 1 min – max - 2) Are there any constraints for the min and max values used in the minmax material due to the definitio...

Dear Sir, I have a problem in using minmax material, I can’t define the min & max values that I can use to get failure in the material after a certain strain. I used: uniaxial material concrete01 1 -2500 -.002 -2800 -0.01 uniaxial material concrete01 2 -2500 -.002 0 -0.005 uniaxial material stee...
