https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/128908/direct-analysis-with-tension-membersGood day I have modeled a structural steel frame building and analyzed it using the direct analysis method, however I have received a few warnings and I would like to know the relevant of these as well as their potential effect on my analysis resultsen-USTelligent Community 12https://communities.bentley.com/thread/393399?ContentTypeID=1Mon, 28 Nov 2016 16:50:57 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:3a369f9b-f440-45f3-86ba-351df9c552c0Sye1. As part of your reference load R1, you have specified a member load as shown below<br /> <br /> 177 179 181 UNI GY -13.442 3.688 <br /> <br /> For a uniformly distributed load, the two parameters you specified, indicate the magnitude of the load and the location within the member where the load is starting from. However a third parameter is missing which is expected to tell the software where the load ends. If the third parameter is missing, a warning is generated and the software assumes that the third parameter is equal to the member length which is 5.33m in your case. In other words the member 177 is loaded with the uniformly distributed load from 3.688m from the start to the end of the member (5.33m). <br /> <br /> 2. The following wiki would explain why you are getting the warnings <br /> <a href="http://communities.bentley.com/products/structural/structural_analysis___design/w/structural_analysis_and_design__wiki/29387.applied-selfweight-is-more-than-total-weight-of-all-structural-elements">communities.bentley.com/.../29387.applied-selfweight-is-more-than-total-weight-of-all-structural-elements</a> <br /> <br /> 3.
