https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/109852/ram-ss---check-self-weight-of-deckIs there any easy way to see how RAM SS calculated the self-weight of a composite concrete on metal deck? I want to find out if it uses the full depth of the concrete or takes into account the corrugations of the deck profile. For example, a 5&quot; slab woulden-USTelligent Community 12https://communities.bentley.com/thread/334539?ContentTypeID=1Fri, 14 Aug 2015 18:24:44 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:b4ae201b-3ba3-472d-9899-f8751ae7d2a5Seth Guthrie<p>Take a look at RAM Manager manual, section&nbsp;7.2 Metal Deck Table File Format. There is a property called AcRib which is &quot;the area of concrete in the rib per foot or per meter of deck width (in.2/ft. or cm2/m).&quot;</p> <p>This value is used for the calculation of the self-weight of the concrete in the deck ribs.</p> <p>The AcRib plus the Ac for the topping times the concrete density + the metal deck self-weight determines the total unit self-weight area load for the deck.&nbsp;</p> <p>Using normal or light-weight concrete is one significant factor, the topping thickness and metal deck self weight properties are others.</p> <p></p><div style="clear:both;"></div>
