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 of 3%.
Natural frequency of soil is 16.53 Hz, frequency of input motion is 5.0 Hz
I used ξ= 3 % for both Target 1 and Target 2
f = 16.53 Hz for Target 1 and f = 5/16.53 = 1.0 (closest odd multiple integer) Hz Target 2
w, α, β are calculated automatically but when I close Material window and edit material, all Rayleigh damping parameters ξ , f, w, α, β are reset to different values. How can I solve this issue?
Q4: How can we plot total vertical wall force on the wall vs time graph in PLAXIS? (Rigid retaining wall) See Pdf file attached
Thank you so much. I have few more questions and send you my model in PM. Please have a look and reply. I will really appreciate it. Once again thank you so much.
