Moment of beams was created by Michele Mocciola
I am trying to calculate a structure composed by beam elements.
I created the mesh, chose the type of element and the loads, but now my problem is: how can I calculate moment and shear of every element?
I would like to use code-aster for civil engineering and for me these values are very important.
Thanks!

Hello,

In linear statics analysis, you can calculate the section moments & forces in the command \"CALC_ELEM\" with the option \"EFGE_ELNO_DEPL\".
Then in IMPR_RESU, add EFGE_ELNO_DEPL to the list of field names to be written:
for example NOM_CHAMP = \"DEPL; EFGE_ELNO_DEPL\"

The components of EFGE_ELNO_DEPL are N, VY, VZ, MT, MFY & MFZ.

I hope my answer is clear enought, if not I can send you an example file.

Good luck

In particular I can't extract single component from EFGE_ELNO_DEPL.
Can anyone help me?

Hello

I have attached an example of a beam with extraction of section forces/moments for post processing.

The mesh and results are MED files, but it works in the same way for any other formats.

When you don't know which quantity you want to extract, you can also ask ASTK to store the \"Base\" (database of all computed results) and open it with \"Stanley\" to interactively extract the wanted values: in ASTK, right click on the \"base\" and select \"Open with: Stanley\".

Stanley is an interactive Code_Aster session which will allow you to calculate new data and plot it in GMSH.

I hope this will solve your problem.

Regards,

J.Cugnoni
