https://communities.bentley.com/products/geotech-analysis/f/forum/231374/norsand---shear-modulusDear 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 helpen-USTelligent Community 12https://communities.bentley.com/thread/718163?ContentTypeID=1Thu, 23 Jun 2022 04:00:03 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:1ea2d79c-0939-4a30-95cb-09202beb849cHung Ho Manh<p>Hello Jason,</p> <p>It should be a small-strain shear modulus of a soil, which can be measured from a Bender Element test or seismic CPT.</p> <p>You may refer to the documents or papers in the link below:</p> <p><a href="/products/geotech-analysis/w/plaxis-soilvision-wiki/52850/norsand---plaxis-udsm">https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/52850/norsand---plaxis-udsm</a></p><div style="clear:both;"></div>
