Thanks Silvia for your friendly help..........................
I use rect path as in Example3.1
I will use quad patch & see the result
Thanks alot...........................

Hi Silvia............ first I will put the case of T-section # Define model builder of T-section # -------------------- model basic -ndm 2 -ndf 3 # Define materials for nonlinear columns # ------------------------------------------ # CONCRETE tag f'c ec0 f'cu ecu # Core concrete (confined) uniaxialM...

Thanks for reply
the problem that I get wrong"very high values"of the deformation when applying Transient analysis & using Linear algorithm with Newmark integrator.........................................

Hi all......... I used 2 type of section Rect-section & T-section with the same depth . when carrying out MomentCurvature such as example2.1 ,I get the same result for the 2 sections............................... I think the problem is OS working with only one value of width........ please help...

Thanks alot............
it works now..................

Hi all............. I am trying to use {recorder Element -file ele1sec1Force.out –time -ele 3 section 3 force}to record the element 3 forces at integration point number 3 but I get nothing in that file {ele1sec1Force.out}.... what is the problem...................................................... ...

dear all.....
I think that the problem is the two values of the width of the beam
so the program failed in working with 2 values of
width and need one only.........

I just asked about the errors that happened when use Newmark with Linear analysis..................

Is this any way to draw the mode shape of an eigen analysis?

Dear fmk,silvia...


there was a problem with damping and elastic models when using Newmark in opensees 1.7.0 ..

Is this problem still in the new opensees 1.7.1?..........

Hi all, I’m working on a simple concrete frame with 1 floor and 1 bay. I used Fiber "T section" to model the beam, and I get the error message {WARNING: CTestNormDispIncr::test() - failed to converge after: 10 iterations NewtnRaphson::solveCurrentStep() -the ConvergenceTest object failed i...
