Hello. I ask you to look at my computation for seismic 9 points. I think I'm doing something wrong. Because the results of velocities and acceleration are too small for seismic 9 points.

Hello guys Could you help me, please I have 02 questions: 1) How do you get the full signal from the load applied over 1 second, knowing that it depends on the frequency each time you change it? 2) Does the load signal given by Plaxis allow me to…

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, 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…

Hey everyone, I want to ask about transformation of curves from dynamic time to frequency domain in plaxis 3D because I need it to calculate impedance functions ??

Good morning, I am wondering if the compliant base at the horizontal base of the model is capable or not to dissipate also downward waves with both horizontal and vertical direction (model with horizontal line displacement for the horizontal component…

Hi, I am using PLAXIS 2D to perform earthquake time-history analysis for a slope using different accelerograms. As a result of this analysis, I will need to estimate the potential volume of soil that may fail and mobilize as a result of the earthquake…

Hi, I am running dynamic slope stability analyses and each analysis is taking around 10 hours. Is there a way to reduce the calculation time. The calculation screen shows that only 1 of 8 CPU cores are used for calculation. Is there a way to dedicate…

Hello Everyone! Does anybody know if its possible to view the plate forces (Bending Moment/Shear/Axial) for a chosen timestep in a dynamic analysis? At the moment I am only able to view these forces at the final step (Step 222, Time = 0.175s) of the…

Good Day Everyone I'm trying to plot a Load- Displacement curve for a Dynamic Analysis on Plaxis 2D but im not sure how to do so since the MStage Method doesnt work for Dynamic Analysis I have the Load-Time curve which I have input as a Load Multiplier…

kindly look to the screenshot. I have El centro earthquake acceleration in "g" unit , and my project unit in "m" and "days" , So I used scaled value 9.8 to transform the multiplier to m/s2 units .. but it seems the displacement of the soil is so high…

Hello, I want to build soil model as the manual " Site response analysis and liquefaction evaluation (2015)". I can't do the perfect validation in the clay layer when inspect the pore pressure ratio. Regarding the setting of clay parameters, is…

Hi, I am currently working on a dynamic modelling project in PLAXIS where we are obtaining the lateral earth pressures on a gravity retaining wall. The retaining wall is modelled as a linear elastic material. To export the results, I have preselected…

Hello! I am currently trying to model my avalache wall with a load given to me in the unit kJ (kiloJoule), this concludes the data I have available about the load in this situation. Is it in any way possible to model this directly into Plaxis 2D,…

I have tried validating PLAXIS 2D for the very simple case of a block connected through a linear-elastic perfectly plastic Mohr Coulomb interface to an oscillating base. The model consists in a large soil cluster of linear elastic material (the oscillating…

Dear Sir, I am herewith attaching images of A)model,1)End of construction, 2)0.2g cyclic loading,3)0.4g loaing 4) case-1 loading(as a line load) and 5) Case 2-line load.The deformed shapes in cyclic loading were may not correct.Why i am getting like…

While I am doing cyclic loading(dynamic time=5s) in RE wall, sigma Mstage is not increasing during calculation.I am herewith giving images of plaxis 2D model and calculation image.Pl.inform the reason.

Hello Sir; Do I need to add a dummy plate when I use the Free field and complain base? If I use drift correction it gave a mistake and I need to deactivate it? And How can I model these boundaries in the plaxis ?

Hello everyone, I am trying to model a science paper in the deep excavation under seismic condition "Seismic behavior and design of strutted diaphragm walls in sand, Mohammad Bahrami" my results didn't much with his results under seismic condition. All…

Hi all, May I ask a question regarding the theory behind the moving loads function in PLAXIS 3D? I understand that users can assignment Movement to point loads with a linear, harmonic or table based signal specifying an initial velocity, acceleration…
