Dear Community
I am doing modelling using the Norsand model. I am not confident with the selection of shear modulus Gref. Should I use the modulus of very small strain (~G0) or that of the large strain (derived from E50)?
Appreciate if you can help me with this.
Hello Jason,
It should be a small-strain shear modulus of a soil, which can be measured from a Bender Element test or seismic CPT.
