I am simulating the experimental data for a free field condition for 1-g shaking with applied harmonic loading. If I am running analysis with HS-small model for dry sand. It is showing error as Accuracy condition not reached in last step. [Error code…
While using PM4 models the effective stress calculation should be based on vu undrained or by using biot effective stress calculations as Pore pressure measurements and liquefaction criteria are the major concern?
if using 'Drained' for Drainage type in General and using PM4Sand in Mechanical tab as user defined, no pore pressures are generated in dynamic phase. Should I use 'undrained A' even for sand type material when using PM4 sand?
Hello Everyone.
I am working on a design of monopiles under cyclic loading condition.
I am using UDCAM-S model. It is clearly mentioned that this model can be used in offshore structures that experience storm loadings.
I am aware that using this…
The pore water pressure above the tunnel is observed to be positive under dynamic loading that results into negative ru, excess pore water pressure ratios. What could be the reason? kindly help me
On using PM4silt for clay and using Undrained A and for sandy soils (PM4sand) Undrained A.is it correct to use this combination while studying for liquefaction analysis?
I am applying input motion data at the base of the model with PGA as 0.349g, time = 34.96 sec. In PLAXIS I am using 40 sec and 4000 steps with subsets =1 as time step is of 0.01 sec. In the results it was observed (the node on the prescribed displacement…
Why liquefied points are observed in soil while using advanced constitutive models PM4sand and PM4silts before seismic loading? The liquefied points were observed in static phase only
I am currently working on a liquefaction analysis using the PM4Silt and PM4Sand models for a layered soil model in PLAXIS 2D. However, I have encountered an issue where the liquefied points are observed in the static stage only before the dynamic analysis…
Am trying to model the effect of thermal loading on the backfill behind integral abutment by using Plaxis 2D. I modelled the concrete bridge deck as Linear Plate element and provide a prescribed displacement near the top of the abutment. The applied displacement…
Hi,
I am a civil engineering student and am trying to model a reclamation project with Plaxis-2D. I was trying to study the lateral deformation caused by wave loading on the artificial island, but since the boundaries are fixed, no lateral deformation…
Hi, im doing a dynamic analysis of an earth dam and I am a little confused of the boundary conditions I need to use because as you can see in the figure my model is moving like a rigid solid. I create a Line Displacement in the bottom with my Displacement…
Hi, I am trying to evaluate the slope reinforced by a row of piles under dynamic conditions (earthquake data).
I want to obtain maximum lateral displacement v/s dynamic time under lateral loading condition. So what should be the boundary condition of…
Hello Everyone,
I know in PLAXIS , when we do an earthquake analysis we define interface boundaries along the side and bottom boundaries . IF I do the same in PLAXIS #D, should I do the same, Please advise.
Thanks ,

Hello All,
I have a question about the hardening soil model. In PLAXIS we have HS and HSsmall for modeling soil behavior. In HSsmall, there is a parameter gamaa_07 to incorporate dynamic behavior which is not included in HS. Also, in the materials…
Hello everybody
I perform seismic analysis in Plaxis 2D model by using a harmonic signal (0.11 g, 1 Hz). I set horizontally fixed lateral boundaries and used absorbent boundaries in dynamic analysis (free field for boundaryX and compliant for boundaryY…
