Dear sir/madam, I have two questions about rayleigh damping parameters. According to the manual and the other references, we know that f1=Vs/4H (fundamental frequency of the soil deposit) and f2 equals to the nearest odd integer (greater one) of the…

I have a pile in a block of sand, with a horizontal load being applied at the top of the pile for 7 seconds, then being released allowing free vibration for 13 seconds. I added 1% damping to the pile and 0.6% damping to the soil materials. After this…

I have a question regarding the determination of mass and stiffness damping parameters of Rayleigh Damping. In Plaxis, I need to determine the target frequencies to calculate the mass and stiffness damping parameters. In the Plaxis manual, it is written…
