forceBeamColumn Recorder Output

Post by gor »

This will be a relatively simple answer for those who know, but could someone write down what the output from the section deformation recorder of a lumped plasticity forcebeam column element. This is, my element is:

element forceBeamColumn $eTag $i $j $GT "HingeRadau $phTag1 $Lp $phTag2 $Lp $intTag"

and my recorder is requesting:

recorder Element -file output.txt -ele $eTag section deformation

which for a 3D beam column element gives me 20 columns of data, for which there is no information on the wiki to describe what these would correspond to.
I should also add that the plastic hinge sections ($phTag1 and $phTag2) are uniaxial sections with a M-phi defined in Mz and have a shear behaviour aggregated into the Vy direction. Perhaps thats makes a difference?

instead of -file use -xml and there should be more info in the file about what each column of data is for.

are you sure about the 20. as looking at the code for HingeRadau there should be 6 sections. i would have thought each section would spit out same number of data points per output.

Thanks Frank. Yeah it is 20, the output is below. Looks like the aggregated shear hinge produces an extra gammaY output.
