Josif Josifovski

Obviously Ru has different definition than ru. The Ru has definition of pore pressure in kPa, and ru is dimensionless ratio. Find out more in the PLX scientific manuel.

Ahmed Hussein Olat

Thank You very much Josif Josifovski

Balasubramanian Ilango

Dear Ahmed, did you find the defintion of Ru (3rd one) in you image? Thank you

Yes I did

Boriana Tchakalova

If Ru=1 then effective stress of soil is zero. So, no shear strength in sandy soil.

Thank You.

Sebastián Abarzúa Sandoval

Sorry but i have a question. If i am analysing liquefaction, is it valid to determinate it with Ru value using the Mohr Coulomb as constitutive model of soil???
