• Interface detached in the output

    Hi all, I am trying to simulate the curling of pavement subjected to temperature differentials at the top and bottom. In the contact surface of the concrete and base course, I defined interfaces and put Rint in the concrete as 0.01 to allow higher seepage…

  • Scaling Contour Not functioning

    Hi Everyone. In Plx 3D Version 22.02.00.1078. I can not change the scaling contour for either the interface stress or the plate forces. Is this issue resolved at 23.2.0.1059 or what can be done? Thank you.

  • Interface stiffness defined by "Direct"

    Dear Support Team, When I applied extremely low ks & kn values for a sensitivity check, I found a gap at the interface before activating the interface element . I suspect that ks & kn values defined by "direct" are applied to the interface element…

  • Well foundation Sinking

    Hi Is there any possibility to check well sinking analysis in plaxis??? How to incorporate the reduction of skin friction due to the projection in well curb and dredging action?????

  • Interface value

    Hi all, I have some questions regarding the interface elements in Plaxis. 01. Soil interface elements is used to represent the soil structure interaction. These interface elements reduce strength and stiffness. Based on reference manual it is stated…

  • Interface between two volumes of Concrete blocks

    Hello, I hope you're all well. Please, I would like to know how to model an interface between two volumes of concrete superimposed one on top of the other, in plaxis 3D, so as to maintain the normal stiffness while allowing transverse/longitudinal friction…

  • Structural Forces around a Mooring Suction Pil

    Hi, I modeled a 90 ft suction mooring pile as a plate and I modeled the soil inside the pile as a very stiff material. Then I applied the design load at the padeye 58 ft below ground surface. I also created external interface around the pile. I…

  • Generation of curve between displacement and normal stress for the node of interface element

    I am extracting load displacement curve considering every step. But right now I am considering node corresponding to the soil. Similarly, I want to plot the curve between two axes which will be having displacement of node on x axis and corresponding…

  • UDSM Interface stiffness from Eoed

    Hi all, In the manual it is mentioned that, when using a UDSM, the interface stiffness must be specified by the user in the form of a power law with Eoedref along with UD-pref and UD-Power. How does plaxis utilize this information? Does it use it to assign…

  • Medel piled raft foundation with volume pile + plate element (for lateral loading)

    Dear All I have modeled piled raft foundation which piles modeled as volume pile while raft modeled as plate element. To simulate soil - structure interaction, I created interface to both raft and piles. In my understanding, correct me if I'm wrong…

  • does shear strength return to zero, when setting tensile strength zero cut-off?

    We are running a shallow foundation with a highly eccentric V-H loading. There will be a separation between foundation and soil near the edge of foundation. In order to simulate the separation of soil and foundation, we have used tension zero cut-off…

  • Picos [204] incorrect solution, slow convergence when boundary and flow conditions are changed in PVD installed soil

    I wanted to create a graph of excess pore pressure vs radial/horizontal distance for an MCC soil model at a particular depth installed with prefabricated vertical drains. To simulate the effect of smear, transition and undisturbed zones around the PVD…

  • Line drains and varying permeability in the horizontal direction in a soil model

    I am trying to simulate the effect of the installation of PVDs on soft soil (soil model used: MCC). The installation of PVD (in this case, a line drain) causes disturbance to the soil and creates three zones around the soil. A smear zone, a transition…

  • Shallow foundation - Soil springs

    Hello, how can we neglect the soil springs between the shallow foundation and the soil beneath it in case where the foundation is sitting on piles and the design requires that all loads are transferred exclusively to the piles? If it's by defining a dummy…

  • Can I assign the value of skin friction to surface in Plaxis 3D

    Hello everyone, I'm trying to simulate the installation of shaft sinking by adopted procedure from kinematic mechanical model, but I'm struggle with the skin friction at the wall of shaft. Can I assign the value of skin friction directly in the surface…
