I would like to model a steel pipe (0.4m dia) carrying methane embedded 1m in ground. Thereafter, I would like to assess the impact of a heavy crane (250kPa) resting on ground on the buried steel pipe.
Is it possible to perform this analysis with Plaxis 2D/3D Ultimate? If yes, how do I model a pipe?
Hi Mathew,
You may use the “Tunnel designer” tool to create a pipe and define loads acting on the pipe. A crane load on the ground surface can be defined as a normal way. If dynamic loads or dynamic analysis is used, PLAXIS 2D/3D ultimate should be used.
Hello Hung,
Thank you. I have modeled the pipe in Plaxis using the Tunnel feature which works. Since the crane would be positioned and not moving, static loading will be applied. Since the pipe will carry pressured liquid, is it possible to model this to represent the true condition?
Dear Mathew,
PLAXIS allows defining a user-defined pore pressure which can be used in this case for modelling the pressured liquid.
Another option is to create a load in the tunnel you created and apply the equivalent pressure on the pipe walls.
Dear Stefanos,
Thank you for the idea. I will check it out.
Hello Stefanos,
The pipe I would like to model carries water at a pressure of 245kPa meaning pressure acts all around the pipe cross-section.
I tried out your suggestion including Plaxis Reference however, unsure on how to model 245kPa of flowing water acting from inside the pipe equally in all directions.
Kindly assist.
