Re: Problem with Fiber stressStrain Recorder in Cyclic M-phi

I forgot to mention that these must be built in because I did not add any additional code.

Re: Problem with Fiber stressStrain Recorder in Cyclic M-phi

I found the uniaxialTest script in another forum post talking about calibrating material models to test data. This is what I use the code for.

Re: Problem with Fiber stressStrain Recorder in Cyclic M-phi

I use the following code to translate a strian history into a stress history with a given fiber. In the code the entire strain history is entered with individual lines of the following code, with one line for each strain data point to be converted to a stress data point. strainUniaxialTest $strain ;...

Re: Problem with Fiber stressStrain Recorder in Cyclic M-phi

I solved the problem. I used the following recorder to get the strain history at the center (0,0) of the section. recorder Element -file 1.out -time -ele 1 section 1 fiber 1 stressStrain Using the output strain hystory for (0,0) and the output curvature history, the strain profile is known at every ...

Problem with Fiber stressStrain Recorder in Cyclic M-phi

I have a cyclic-moment curvature analysis which matches experimental data well, but I cannot get the rebar fiber stressStrain recorders working properly to compare strain data. My intention is simply to impose the recorded curvature history on the fiber section and compare the resulting moments and ...
