Modelling Beam or Embedded Beam

SOURAV KUMAR AGARWAL — Tue, 30 May 2023 06:11:35 GMT

Hi,

I am trying to model the dowels between the structural plates of central wall in a tunnel as embedded beam. The plates are vertically standing with no contact with the soil. Is this a correct modelling approach to move forward with. I understand Plaxis has an option of modelling beam elements as well. Will modelling the dowels as beam or embedded beams make any difference in shear forces if there is no contact of the element with the soil? Please advise.

Thanks

PLAXIS 3D - MESHING

SOURAV KUMAR AGARWAL — Wed, 29 Mar 2023 11:29:51 GMT

Hi,

I have a query regarding the meshing to be done in Plaxis 3D. I am modelling Tunnel Segments and am trying to model the joints between individual segments (Expansion Joints). Since the thickness of the joints are very less (around 25mm) as compared to the length of tunnel segment (50m). The mesh is being generated but with EMR warnings. Is it advisable to move ahead with the analysis considering very low-quality mesh (Quality spheres in range 10e-3)? If yes, Arent they going to effect the results?

If not, what could possibly be the best way to model the expansion joints in Plaxis 3D?

Thanks.

Python- g_o.Plates

SOURAV KUMAR AGARWAL — Tue, 28 Feb 2023 06:21:08 GMT

I am trying to run the Python command in Plaxis using the Visual Studio Code, the server is getting connected, however when I try to access all the plates/phases using the following command, attribute error is observed.

Code:

plate= [plt for plt in g_o.Plates[:]]

phase= [p for p in g_o.Phases[:]]

Error:

Traceback (most recent call last):
File "C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution V2\python\lib\site-packages\plxscripting\plxproxy.py", line 183, in __getattr__
    return self._getattr(attr_name)
File "C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution V2\python\lib\site-packages\plxscripting\plxproxy.py", line 120, in _getattr
    raise AttributeError("Requested attribute '{}' is not present".format(attr_name))
AttributeError: Requested attribute 'Plates' is not present

However, I try to run the same in the in-built Jupyter Interpreter and print it, the code runs with all the plates and phases.

Can you assist on what the problem could have been?
