Element recorder for forceBeamColumn

Post by tguha »

Hello,
Can someone kindly explain the output of an element recorder when recording the force, deformation and stressStrain (fiber) of a non-linear beam column element (forceBeamColumn) used as a beam in a 3D problem subjected to both flexure (along local y and z direction) and torsion (along local x direction)

force – section forces

example: recorder Element -file ele1sec1Force.out –time -ele 1 section 1 force

deformation – section deformations

example: recorder Element -file ele1sec1Defo.out –time -ele 1 section 1 deformation

I was expecting to get six forces (Fx, Fy, Fz, Mx, My, Mz) and 6 deformations (x, y, z, rx, ry, rz) corresponding to forces and deformations at the section but I get only five (and I am not sure they correspond to which of the above quantities).

For stressStrain – record stress-strain response.

example: recorder Element -file ele1sec1StressStrain.out –time -ele 1 section 1 fiber $y $z <$matID> stressStrain

I get only a single column of stress and strain response. Is this the resultant stress and strain at the specified fiber in the section??

Regards

instead of -file try -xml and look at the description for the components.
