https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/167909/bearing-pressure-in-ram-conceptHi I am designing mat foundation in Ram concept. What difference are maximum and minimum bearing pressure plan? How calculate the value? Is it depending on the loading direction? Which one do I use it for design?en-USTelligent Community 12https://communities.bentley.com/thread/682861?ContentTypeID=1Wed, 17 Nov 2021 19:14:33 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:a7f6398b-8911-448e-92b5-90daade4df42Seth Guthrie<p>Any load combinations with Active Rule Set = Soil Bearing (those are service combos by default).&nbsp;</p><div style="clear:both;"></div>https://communities.bentley.com/thread/682860?ContentTypeID=1Wed, 17 Nov 2021 19:09:39 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:fe8bfd86-ad61-4673-9dc9-2c072eaf8115Beth Zetzman<p>Seth, which load combinations do the max and min soil bearing pressure plans use?

You can plot the bearing pressure for individual load combinations, however.&nbsp;</p><div style="clear:both;"></div>https://communities.bentley.com/thread/500388?ContentTypeID=1Thu, 10 Jan 2019 19:01:13 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:03524083-fa7c-48d1-9c3a-61cba9abf178Karthik Madhur<p>@ Seth: Does RAM Concept specify for which load combination specifically am I getting the Max and Min values for the bearing pressure?&nbsp;</p><div style="clear:both;"></div>https://communities.bentley.com/thread/481190?ContentTypeID=1Wed, 12 Sep 2018 18:47:37 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:902320e2-e88e-4b2c-8f3c-b5935b63a8bdSeth Guthrie<p>In Ram Concept, for soil bearing design, there can be several load combinations, and potentially several load patterns that each produce spring reactions, and by extension soil bearing pressure values. Ram Concept envelopes all of these cases and then plots the largest compression values in a Max Soil Bearing Pressure plan, and it plots the minimum values (potentially negative values) on the Min Soil Bearing Pressure plan.&nbsp; The Max pressure plot is important for checking if the allowable pressure is exceeded. The minimum plot is important for checking stability.&nbsp;</p> <p>For further reading, check out these topics is the program manual:&nbsp;</p> <ul> <li>Chapter 11 Specifying Load Combinations</li> <li>Section&nbsp;30.1.6 Zero tension iteration options</li> <li>Chapter 32 Plotting Results</li> <li>Section&nbsp;53.9 Result categories in RAM Concept</li> </ul> <p>Also these prior posts:&nbsp;<a href="/search?q=ram%20concept%20soil%20pressure&amp;group=326#serptag=ram%20concept">https://communities.bentley.com/search?q=ram%20concept%20soil%20pressure&amp;group=326#serptag=ram%20concept</a>&nbsp;</p><div style="clear:both;"></div>
