https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/186410/1-way-shear-effective-depth-calculationI have an existing two-way slab that I am trying to analyze. At locations of negative bending, the effective depth for one way shear calculations is much smaller than I&#39;m calculating it to be by hand. Based on the value that the audit is showing, iten-USTelligent Community 12https://communities.bentley.com/thread/546761?ContentTypeID=1Wed, 02 Oct 2019 16:05:20 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:e1f052dd-9c27-448a-9f2c-f86ddc8deddbJessica Dineen<p>Thanks, Seth. I tried running it neglecting axial forces and it was still giving an error. However, when I increased the spacing of the sections it solved the issue, as the error was occurring at the inflection points.</p><div style="clear:both;"></div>https://communities.bentley.com/thread/546757?ContentTypeID=1Wed, 02 Oct 2019 15:49:25 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:cf4843d4-72fd-4982-80a6-dcf80adfe8e0Seth Guthrie<p>See this for details:&nbsp;<a href="/products/ram-staad/w/structural_analysis_and_design__wiki/3094/ram-concept-shear-reinforcement-faq">https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/3094/ram-concept-shear-reinforcement-faq</a></p> <p>Where you have net axial forces this can cause a small, or unexpected depth to the tension reinforcement. In flat, RC slabs some users might neglect the net axial force, but I don&#39;t generally recommend that. Adding some rebar to the opposite face can sometimes help, or re-spacing the design sections if it&#39;s limited to only a few specific locations (i.e. near inflection points).</p><div style="clear:both;"></div>
