neglect self weighthttps://communities.bentley.com/products/geotech-analysis/f/forum/238548/neglect-self-weightexcuse me, I am modeling caisson using segment elements, these segments do not put directly on the soil at the bottom, IS there any option in plaxis 3d to neglect the self-weight of segments but keep the stiffness of it?

But, again, you are asking me a closed-ended question about something I have no information on.<br />The best way to see if that parameter affects the outcome of your analysis is to run a calculation with and without weight and compare the results.</p><div style="clear:both;"></div>RE: neglect self weighthttps://communities.bentley.com/thread/742676?ContentTypeID=1Tue, 22 Nov 2022 09:19:54 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:27bad9b5-e23d-4888-95d8-cd40563b837eDhyaa Alhaq Abualghethe<p>The segments&nbsp;are a ring (circler caisson) that uses in tunnels, I modeled these rings as volumes, it is possible to put&nbsp;<span>(&gamma;&nbsp;
