https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/71070/staad-pro-optimization-parametersI just started using STAAD Pro through my college. I am modeling a steel structure and would like to automatically optimize the structure based solely on total deflection (global maximum deflection) and weight. I want each value (deflection and weighten-USTelligent Community 12https://communities.bentley.com/thread/187417?ContentTypeID=1Wed, 19 Oct 2011 16:21:27 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:7e37a38e-95ba-45eb-b0d8-a0581580671dSKLose<p>Currently, optimization (member selection) in STAAD can be done on the basis of only 2 criteria</p> <p>1) That the program choose the least weight section that meets criteria for strength and slenderness of a specific code (US, Canada, Europe, Britain, etc.)</p> <p>2) That the program choose the least weight section that meets a user specified limit for the ratio of member length to deflection. </p> <p>For the second condition, the deflection we are referring to is the deflection of individual members. There is no method currently available to perform a member selection that would modify the stiffness of the structure in such a way that the deflection of nodes will fall within some user specified limits.</p><div style="clear:both;"></div>
