• Input ground-motion in free-field site response analysis

    Hello there, I am performing a free-field site response analysis. Plaxis's Manual suggests to set a " Compliant base " for the bottom boundary and " Free-field " for the lateral boundaries. Now, in my specific case i have an outcropping ground motion…

  • What will be the staged construction phases if an existing tunnel is modelled which is embedded into the soil under seismic loading?

    I have to model an existing tunnel and perform the analysis under seismic loading. What will be the phases for staged construction in PLAXIS 2D?

  • Dynamic analysis - Boundary Conditions

    Hi there, I am applying the earthquake time history as a prescribed displacement at the base of the model. The problem I am encountering when the strong shaking starts is that the side boundaries deform too much - see below. My lower boundary is a compliant…

  • Natural frequency, Mesh element size, Rayleigh damping, vertical force on retaining wall model

    Q1: Is there any way to determine natural frequency of Retaining wall soil numerical model from PLAXIS? Q2: How can we see the exact element mesh size in PLAXIS? Q3: I am using Mohr-Coulomb soil model and want to introduce constant Rayleigh damping…
