I am utilising the hardening soil model for settlement estimates of foundation loading. My question is, do I needen-USTelligent Community 12https://communities.bentley.com/thread/686272?ContentTypeID=1Wed, 08 Dec 2021 06:25:15 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:0a6b8158-55e0-4eb8-a62f-88b5db2c7b9eAri Surya Abdi<p>Dear Marcus,</p> <p></p> <p><span>Reference pressure (Pref) of 100 kPa is&nbsp;generally selected since a good percentage of triaxial tests can be assumed to be performed on 100 kPa all-around pressure. You can refer to the below papers to get&nbsp;a better understanding of determining Eur for input parameters using e and Cs.</span></p> <p><span></span></p> <p><a href="http://yo-1.ct.ntust.edu.tw/jge/files/articlefiles/v5i120100525218817485.pdf">http://yo-1.ct.ntust.edu.tw/jge/files/articlefiles/v5i120100525218817485.pdf</a>&nbsp;</p> <p><a href="https://reader.elsevier.com/reader/sd/pii/S0266352X16301057?token=948D8B8B0F175DD00D2F1C276632F8B196F8A37A526E7914495BE94FAB1D08ECC779BBA98417ED7DEB8941591E11E2BA&amp;originRegion=eu-west-1&amp;originCreation=20211208062522">https://reader.elsevier.com/reader/sd/pii/S0266352X16301057?token=948D8B8B0F175DD00D2F1C276632F8B196F8A37A526E7914495BE94FAB1D08ECC779BBA98417ED7DEB8941591E11E2BA&amp;originRegion=eu-west-1&amp;originCreation=20211208062522</a>&nbsp;</p><div style="clear:both;"></div>https://communities.bentley.com/thread/684415?ContentTypeID=1Fri, 26 Nov 2021 20:57:05 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:1306bffa-f0fd-428c-871a-9bd79b0b1166Jamal Hassan<p><a href="https://berkdemir.github.io/">BD &middot; Tunnels, Geotechnics and Codes (berkdemir.github.io)</a>&nbsp;check here under hardening soil.</p><div style="clear:both;"></div>
