beamwithhinges element recorder

Post by UMUT AKIN »

Hello everyone,

I am trying to find out the moment curvature results of a beam element after a cyclic analysis but the results file is a bit confusing. More clearly, when I set the recorder as
"recorder Element -file ele3Rotat.txt -ele 3 plasticRotation",
it works and gives a file with 3 columns of data whereas when I try to precisely find out the plastic hinge rotations and set the recorder as
"recorder Element -file ele3Rotat.txt -ele 3 section 6 plasticRotation",
the resultant file is empty. the same is true for also sections 1,2.3.4 and 5.

Moreover, "recorder Element -file ele3Global.txt -ele 3 section 6 force" command works and gives the results correctly despite the section is also defined.

Thanks in advance.

You can record force at the section but plastic rotation is not related to section but to plastic hinge region so you can not record it at the sectional level.
