Can I use stressStrain recorder in zeroLengthSection ele?

Post by huyuntian »

Hello everyone,
I'm trying to use zeroLengthSection element to analyze moment-curvature of RC sections.
I can get the result of moment and curvature through:
"recorder Node -file ** -time -node * -dof ** disp;" and everything is alright.
But command like :
"recorder Element -file Element1.out -time -ele 1 3 section 1 fiber 0.10 0.10 stressStrain"
doesn't work, nothing is recorded.
I don't know whether if the element kind, zeroLengthSection, cannot have a stressStrain recorder, or my usage is wrong.

there probably is no need for the 1, as there is only 1 section in the TrussSection.

Dear Frank,
I am using zeroLengthSection for bondslip and my problem is with recording shear.
I use these commands and the problem is that it gives only possitive shear, while without the zero length the shear I have a real hysteresys

recorder Element -file Data_BeamWithHinge/ReacBase2.out -time -ele 8 section force
recorder Node -file Data_BeamWithHinge/ReacBase.out -time -node 1 -dof 1 reaction;
recorder Element -file Data_BeamWithHinge/ReacBase3.out -time -ele 8 globalForce
Is there any trick to recording shear when it comes to this element?
Thank you kindly
Maryam

I think you should get reasonable shear forces with the third recorder. Isn't it the case?
