Dear Vesna!
I want to know if and how the Platefiber section considers shear deformation?

Dear All, I've used PlateFiber section command for modeling concrete shear wall. The applied material is also PlateFiber material. In my research, an elastic isotropic material has been selected and used for the shear wall material. The model is complete and the results are good. I've sent the paper...

Dear Ali,

How do you model your wall? do you use shell element?

Dear Vesna!

I've Found my mistake!

Tnx

dear Vesna
tanks for your answer!
I tried this command for a beam in a simple symmetric steel moment frame with nonlinearbeamcolumn elements, but the plastic rotations at two ends were different!
I am confused and do not know the problem!

Dear Vesna!! I saw in a post here, that you answered one of the questions about the plastic rotation....your answer was: "To get plastic rotation of plastic hinges for element 1 here is the command: recorder Element -file Element1.out -time -ele 1 plasticDeformation The file will contain 4 colu...

dear all professional openseesers!

Can i record the rotation at one of the nodes at the end of the beam and then minus the yield rotation of the beam to calculate the plastic rotation at that end?! is it true?!

dear all

i want to calculate plastic hinge length to get the plastic rotation using this parameter and curvature......for a steel section, how can i calculate the plastic hinge length?

tnx

Dear Vesna thanks for your answer, but what kind of deformation of a section should i record for curvature? (in a 2 dimention problem: 1, 2 or 3?) and, are the following formulas correct for the calculation of the plastic rotation using the curvature? Lp = (L/2)*(1 - final_moment/yeilding_moment) Pl...

Dear vesna and all other proffesion openseeser! I've modeled a 1-bay 1-story steel moment frame and subjected it to an earthquake record. I want to record plastic rotation for the beam.As you know, the plastic rotation should be evaluated using the curvature. I have some questions: 1. what kind of e...

hi vesna
what about plastic rotation?
I hope there exists another way except from curvature!

Hi Silvia and other perfessional OpenSeeser
i have modeled a one-story one bay steel moment frame. I've used beamwith hinges element for beams. But i cannot record rotation and stiffness for this element.
may you please help me?
