forceAndDeformation Recorder

[jovillarroelb]

Hi everyone;

In a 3D model, I'd like to know what are the 8 columns of the "recorder element .... forceAndDeformation". I know some of them are moments and other curvatures, but which one is what?

Thanks!

Looking the values I supose they are:

Axial deformation, Curvature X, Curvature Y, Curvature Z, Moment X, Moment Y, Moment Z and Axial Force.

Is this right?

depends on the element type.

What of is my element is dispBeamColumn?

[fmk]

are you recording something from the section or a material in a section? The dispBeamColumn element itself does not respond to "forceAndDeformation"

I made a time-history analysis and recordin forces and displacements to compre them with the element capacity. I also want to graph the points of the history against the Moment-Curvature, and see if those points are above or beneath that curve. This is the reason why I need this type of recorder.

Thanks!
