    When analyzing the truss discussed here using non linear analysis also giving partial moment release value of .9, the static checks are not satisfied for both force and as well as moment. How to rectify that?
    I am trying to analyze a simple beam with pin support at both ends and a internal pin in between using non linear analysis but static check are failing. How to rectify that?

    Good Evening sir, as we are changing the percentage in moment release, how are these applied exactly on ground ? Like an example, you release a secondary beam of a RCC structure in staad but can you construct that kind of connection on ground ? Can you guide please. Thanks

    Sir, in one of the structure which was being discussed at 34 min was with all pin supports and 44.5 min again with all pin supports but why the latter one was only failing due to pin supports ? And are these RCC or Steel structures ?? Should we have pin supports on one side and fixed on other side in a PEB ?

    is this warning will appear ? if we do not apply any lateral load Fz.

      Warnings will be reported if there is any instability condition present in the model and reporting does not depend on whether there is any load in that direction or not. On basis of the load application, you need to decide whether the warning is harmless or you need to rectify the structure.

      @Dawson Graysen thanks for your reply. I found the site through google and I'm in the hacking process now.
      I see it takes quite some time so I will get back to you later with my results.

      @Dawson Graysen it did the trick and I finally got access to my account again. I am so happy!
      Thank you so much, you saved my account !

    Static Check Results do not show the results for load combination, it shows the primary loads only. Can you advise ?

    • @surojit_ghosh
      @surojit_ghosh 3 года назад

      Static check results are reported only for those load cases which are analyzed. Load combinations are just the algebraic sum of results and hence it is not reported under statics check results. If you want, you can convert the load combination cases to repeat load cases - then under static check results, those loads will be reported.

    In my structure some warnings are like no member is loaded for the floor load generation.
    But I found my all floor loads are assigned properly in load case details as well as reference load cases.
    So why this type of warnings are there and how to rectify those warnings?
    Please guide.

    • @surojit_ghosh
      @surojit_ghosh 4 года назад

      This warning indicates that for the applied floor load, there are few members present which are not subjected to any floor load component. You can isolate the floor load and use PRINT LOAD DATA command to investigate this issue. For more information, you can go through Bentley Communities site (communities.bentley.com/products/ram-staad/f/ram-staad-forum) where similar type of problems has been discussed.

      Thank you for reaching out. Are you looking for a product to perform the structural design of the manhole cover or are you looking to sizing for water flow?

    This problems makes StaadPro very difficult to use and especially when models become more complex.
