Reason for slow STAAD.Pro model analysishttps://communities.bentley.com/products/ram-staad/f/ram-staad-forum/207308/reason-for-slow-staad-pro-model-analysisHello! I would just like to ask I am working on a big model like 25m by 180m and upon running the analysis, it stopped at RUN BY LOAD CASE or something. So I took a part out and removed some plates and turned all braces into truss members.

The fact that you have almost 600 load cases is causing the analysis time to be long. For me using the above version, the analysis completed in about 33mins which is not too bad ( see picture below). If you need a quicker analysis you may consider changing the REPEAT LOADs to LOAD COMBINATIONs. The analysis you are trying to do is linear and so I don&rsquo;t see an issue with using LOAD COMBINATIONs. That would significantly reduce the analysis time.</p> <p><img alt=" " src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1607981074437v1.png" /></p><div style="clear:both;"></div>
