RE: Interfaces around corners
Vasileios Basas
Hi João, I would say that your approach is correct. Although it is not always necessary, it is a good modelling practice to prevent stress oscillations by specifying additional interface elements inside the soil body. However, remember that these…

RE: Dynamic analysis
Dennis Waterman
Dear Boris, 1 ) The easiest solution is to have the the material for which you want drained and undrained behaviour 2 times. So you have 2 material sets with all the same parameters, but one is drained and the other one is undrained. Then calculate…

Dynamic analysis
Boris Kolev
Hi there, I am in the process of conducting a dynamic analysis on a deep excavation (>28m). The water table is close to the surface and the excavation wall consists of secant wall and anchors. Therefore, I am running a coupled flow analysis during…

RE: Modelling building slabs?
Stefanos Papavasileiou
Dear Jamal, I would take it down to the basics: what does a node-to-node anchor simulate? A node-to-node anchor is a linear structural element (also considers an out-of-plane spacing in 2D) which can handle only axial forces, no bending or shearing…

RE: Group effect of piles in Plaxis 3D?
Faseel Khan
Group effects can mainly be categorized with respect to pile spacing. If piles are far enough apart then there is no evident soil-pile interaction. If piles are little closer together then there is minor soil-pile interaction. If piles are even more close…

RE: Regarding Plaxis Licence?
Stefanos Papavasileiou
If by app you mean PLAXIS, then it will be fine. As explained in the link, we record usage when the application is running. Checking the Forum (nice!) or the Wiki (even nicer!) is not recorded as PLAXIS usage as long as PLAXIS is not launched on that…

RE: Modelling MSE Walls in Plaxis?
Stefanos Papavasileiou
Dear Jamal, Resetting displacements to zero is a feature to simply reset the counter of the already recorded deformations to zero. We have an article describing it in detail: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision…

RE: Regarding Plaxis Deformations>Rotations?
Vasileios Basas
Hi Jamal, PLAXIS shows only the total (elastic+plastic) deformations/rotations for structural elements in Output. You can, however, try to calculate the plastic (hinge) rotation manually. Alternatively, you can check whether the plate element reaches…

RE: Compliant base for dynamic analysis
Dennis Waterman
Dear Jamal, If you have data that is indeed only upward motion data you can use u=1.0. I'm not so sure though that PEER data is upward motion data, so you would have to check that. With kind regards, Dennis Waterman

RE: Hardening Soil Model-value of power m
Berk Demir
Hi Jamal, you have some problems with the understanding of embedded pile and I would strongly recommend you to take a look at the reference manual again. In the example you give, you have to enter 157 kN/m all along the length, not linear. Plaxis will…

RE: Hardening Soil Model-value of power m
Berk Demir
What I tried to tell in that slide was always enter ultimate (characteristic values), because pile behaviour is non-linear, and you have to use characteristic values to simulate piles in Plaxi - to get the correct deformations.

RE: Regarding the E50, Eoed and Eur in HS small?
Dennis Waterman
Dear Jamal, Based on the kind of soil and experience you could indeed assume a certain ratio. Alternatively you would have to determine it through some test. For instance a triaxial, oedometer or DSS test with unloading to determined Eur or Gur ...…

RE: Regarding PLAXIS 2D model depth?
Stefanos Papavasileiou
Dear Jamal, Defining the size of the model is one of the first and important steps when modelling with any finite element software. The model boundaries should be far enough so that they do not affect the area of your model. Why is that? Because in…
