Hello,
I am designing a cantilever soldier pile as shown in the image. The soldier pile has an embedded length of "D" in concrete and an exposed length of "H-D". The soldier pile has a given section of W 18x32. I know Plaxis does not has a provision to input the "I" section. I plan to approach the problem with two embedded beams ( one for the soldier and one for the cement grout) as shown in the figure. I see in PLAXIS it says as lines overlap. How can I resolve it, please advise.
Thank you,
Faisal
Hi Faisal,
In PLAXIS, you can have a chain of two lines: one line being the bottom embedded part of the beam (L = D) and the second line being the top exposed part of the beam (L = H-D). However, you cannot create a line (L = H) and, on top of that, draw another line (L = D). That doesn't work.Some care is also needed when defining the connection point for the embedded beam (PLAXIS 3D) or embedded beam rows (PLAXIS 2D). By implementation, the connection point of an embedded beam element can only be at the top or bottom (first or second). You can refer to our Reference Manual for more details about the available options.
Hello Vasileios,
Thank you very much for your reply. Can you suggest me with an idea as how should I approach the situation of a full beam being enclosed by concrete as shown above. Much appreciated.
Thanks,
Hi Faisal,Depending on your modelling needs, you can use any combination of a beam (PLAXIS 3D), plate (PLAXIS 2D), and embedded beam elements. For example, in PLAXIS 3D, one idea would be to select a beam element for the free part and an embedded beam for the encased part of the beam. Using a beam for the top part also ensures a correct connection with other structural elements (e.g. lagging, wailing beams or struts).

The embedded part should be defined as "grout", am I right?
Also, if I use a "beam" element, then will the connection point be specific to "top" and "bottom" only.
