Modifying Element Recorder

Hi Vesna, I would like to record the axial strains of a truss element. The default for the recorder is to save the deformations rather than strain. Is there any way I could introduce the truss length as a factor so the axial strains are recorded so I don't have to import them into Matlab and calcula...

Re: Modified Masing Hysteresis Criteria

Thank you so much Frank, It seems working but there is an issue: The purpose of recording the properties of each single loop is that if the new generated loop is going to intersect the previous loop, it is supposed to follow the previous loop. Therefore, if such a case happens the numClosedLoop drop...

Re: Modified Masing Hysteresis Criteria

Could you please just introduce me to one of those uniaxial material available in OpenSees which uses the above concept. So by looking at that I get an idea how it is done. I have finished coding every thing in c++ so I have a fair understanding how c++ works. Thanks a lot.

Re: Modified Masing Hysteresis Criteria

Thank you Frank, May I also ask how to use them in the .cpp file? Suppose I introduce the state variables in the .h file. And suppose each of my cycles has a curvature variable which might be different from the other cycles. Can I record only the curvature variable phi for each cycle in order. So at...

Re: Modified Masing Hysteresis Criteria

Thank Frank,

But could you please suggest me how to add state variables? can you please give me some hints. I don't know what you mean.

Truss element with Uniaxial materials

A truss element can be used with a uniaxial material like Elastic which can define either force-deformation or stress-strain relationship, so why this element can produce only force and deformation as output. How does it understand if my inputs for Elastic material were modulus or stiffness?

Re: Deformation of previous step, Can I record it?

I have a problem similar to Pejman. I have created a simple material model comprising of loading/unloading curves. During analysis, I want my curve to follow the previous loading/unloading curve if the current one intersects with the previous one. For this to happen, I need to save the parameters of...
