I want to ask a question regarding piled-raft modelling in PLAXIS 3D.</p> <p></p> <p>Currently, I am modelling the raft as a volume and the piles as embedded beam. As in the theory stated by Poulos (1994), the load-settlement curve of the piled-raft foundation generally should look like this.<br /><img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/343671/pastedimage1680712441637v1.png" alt=" " /></p> <p>But currently in my model, the model has collapsed even though it is still far-far away even from the ultimate load of the raft foundation. I found out after that the reason for the collapse is because the capacity of the embedded piles have all been mobilized. This causes me a real problem because it means that I can&#39;t be able to model the Curve A-B as specified in the picture I attached. It&#39;s as if the model behave like a slab on pile rather than a piled-raft.<br /><br />Can someone please provide me an alternative or solution regarding this problem? Appreciate it very much</p><div style="clear:both;"></div>https://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Wed, 05 Apr 2023 05:15:52 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:e18fe50e-30fc-43db-874f-f4768cec89f9Ask a question in a forum.
