Hi everybody!

I have the same problem in my project.
can anybody help us?
thank you in advance!

thanks dear fmk, but there is a problem. the values of plastic rotations about the Y (the second and third components) after applying the gravity loads are more than the rotations about the Y that computed using the basicDeformation recorder!!! the recorder for computing plastic rotation: recorder E...

Hi everyone,

what is the six components of plastic deformation recorder for forceBeamColumn elements in 3D modeling?

element used:
element forceBeamColumn 1 1 5 $BeamTransfTag "HingeRadau 11 .25 11 .25 110"

recorder:
recorder Element -file ele.out -ele 1 plasticDeformation

thanks dear fmk for your answer

Hi everybody, I have modeled a 3D 10-story steel building using forcebeamcolumn elements. the building has 3 bays in every direction ( x and Y). I want to perform an eigenvalue analysis. but, when the code runs the following message appears: "Opensees has stopped working" what is the probl...

Thank you very much dear fmk!

Hi I modeled a 10-story steel moment resisting frame using fiber sections and nonlinear elements. Nonlinear time history analysis of structure under a special record was performed. An eigenvalue analysis was carried out after each step of nonlinear time history analysis and the variation of modal pe...

Thanks Dear fmk for your answer
It's solved.

Hi I have a question about an adaptive displacement-based pushover analysis. as you know, in an adaptive pushover procedure an eigen analysis should be done in each step to compute the lateral load pattern. then, the structure is pushed by this pattern. I have used recorders to extract the modal sha...

Hi I've modeled a 2-D steel moment frame and analyzed it using pushover method. forceBeamColumn element has been implemented in the analyses. my problem is some confusing results. for example, in the last step of analysis the results for basicDeformation and plasticDeformation recorders for a specif...

Hi
you can use "loadConst -time 0.0" command after the first stage, and then do the second pushover.

Hi dear friends;
I am performing a displacement-based adaptive pushover analysis. I need to apply an incremental displacement in every step of analysis instead of an absolute displacement. if I use sp command, an absolute displacement will be applied. can anyone help me, please?
Thanks

Hi, I have modeled a 3-story, 3-bay steel moment frame to perform nonlinear time history analyses. I have used nonlinear beam column elements with fiber sections. my difficulty is the convergence problem, even when a weak earthquake (PGA=0.1g) is implemented. I increased the number of iterations, bu...

Hi everybody! I've modeled a 3-D, 10-story steel moment frame using nonlinearBeamColumn elements. the model has 2 bays in X and Y directions. I,ve taken into account the torsional stiffness by section aggregator. the first three periods of structure are: 1.208, 1.168, 1.137. But, they are 1.700, 1.4...
