• Modal Frequency Calculation output details

    Good day, everyone! My query is about using the Modal Frequency Calculation... I've been checking the modal frequency of the structure as a whole but the client asked how we deal with the concentrated loads in the middle of the beams. I said that…
  • How to get a natural frequency for a particular beam/ element in STAAD?

    Good day everyone! Say I have a equipment supporting structure and I was tasked to get the frequency of a supporting beam of an equipment, is there a way to get this specific beam's natural frequency alone? Thank you.
  • RE: WIND

    Your modal analysis looks correct. The only change I would suggest is to use positive values for all the loads when you are doing a modal calculation, as these loads are only used to calculate the masses. A modified file is attached for your reference…
  • RE: Could I input Pump Frequency in Staad to find natural frequency of pump support structural steel

    The natural frequency calculation for the structure is based on a free vibration analysis. So you do not need to input the machine frequency for that. However you can find out the response of the structure to the vibrating machinery by carrying out a…
