  • How to Modify Notional Load Factor Applied to Auto Generated Load Combinations in STAAD.Pro Connect Edition?

    The default notional load factor applied to gravity loads when using the automatic load combination generator is 0.002. Is it possible to automatically generate load combinations in the most recent version of STAAD with a notional load factor other than…

  • "Bentley.Staad not responding" when using notional loads for Direct Analysis

    I am using STAAD Connect version 21.00.02.43. I have been trying to create a staad file for direct analysis with notional loads.However, when opening the file as indicated in the image, the software stops responding. This does not happen when removing…

  • What is the difference between ITERDIRECT and PDITER options for PERFORM DIRECT ANALYSIS command?

    My understanding is that with the PDITER command with every PDelta Iteration the Taub values for Direct analysis is computed and the iteration stops when Taub converges. In which case I cannot understand the purpose of the ITERDIRECT command. Could…

  • RE: Notion load factor for 0.002 or 0.003

    Regarding 1, in Direct Analysis the Taub values are determined iteratively based on the axial force in the member. When you set the notional load factor to 0.003 these iterations are not carried out and Taub is considered as 1 which is what the code recommends…

  • RE: Blast analysis using Direct analysis method

    It would not be appropriate to do a direct analysis with a time history loading. Instead what you can do is a Direct analysis for all other cases and then analyze the time history loading using a PDELTA KG. That accounts for the pdelta effects in the…
