Beam formulation Plaxis and Geostudio

[jedij]

Hello!
I was wondering does anyone knows which type of beam formulation (Euler - Bernoulli or Timoshenko) does Plaxis and Geostudio uses. I tried to find out throughout manuals but there isn't any clue.
Thanks
Best regards

Geostuido uses Euler - Bernoulli type of beam and formulation, and I foud out that Plaxis maybe using Timoshenko type of beam.
