How to measure rotation angle in a steel base plate ?

[MosBrowning]

Dear all

I'm modelling a Steel column base plate subjected to Moment ,the model is fine and output results are quite reasonable.

Now I'm validating the Model with Experimental test results that have Moment - versus - rotational angle in radians plotted in curves.

so the question is :
Is it possible to obtain the base plate rotational angle at a certain vertical cross section or not ?

if not, shall I start to calculate this rotational angle manually (which might be quite inaccurate) ?


Thank you in advance

Regards.

In what way is the output you want different from UR ?

Dear Sdebock

Thank you very much for caring

The question is how to obtain an angle of rotation of the base plate ?

I can get Stresses, Deformed shapes and some (not very useful) plots

but I can't find where to obtain a rotational angle

is it possible to obtain such rotational angle or shall I calculate it manually ?

Thank you again

Regards.

For a plate (aka shell) you can get output UR which is nodal rotation.
If, for some reason, you are modeling the plate with solid elements and you don't have nodal rotation:
An easy solution is to overlay your surface with a shell with almost 0 thickness with the same nodes as your structure.
Or you could tie a reference point to where you want, or connect some nodes with (cartesian/cardan) connectors and ask for CUR output.
