modeling apply support settlement

User: "wenliang"

Hi, 

Currently i am doing a project which is to assess an existing building close to ground excavation.

Part of the building columns (supporting on pile cap) will experience settlements.

Main purpose is to check what is the impact on the structure frames due to the settlements.

Please advise how should I apply the settlement on the column supports in analysis modeling.

Thanks

    Hello Wenliang,

     

     

    Thank you for contacting us via the Altair Community Forums. I see that you might have also sent this question to sframe-support@altair.com, as there is a case created for this question on our support platform, called Service Now. I have responded to your inquiry over there. Can you go to Service Now to check my comments? For your reference, the case number is CS0419601.

     

    Thank you for your attention to this matter. We can continue with our discussion on Service Now. We hope you find our comments helpful.

     

    Kind regards,

    Hello Wenliang,

     

    For future reference, and for other users that might ask themselves the same question, I will post my comments from the case on Service Now here as well:

    There is a tool dedicated to applying settlements on supports on the Loads window: the Support Settlement Tool. When using this tool, you will be able to apply a support settlement load (a displacement), which the solver will take into consideration when calculating the support reactions. You will be able to determine the displacement's magnitude, and its direction (one of the 6 existing DoFs; translation for the X, Y, and Z axes, and rotation about the X, Y, and Z axes):

    Additionally, if you were to run a nonlinear analysis on the structure, you can also use the displacement control method, which can be toggled on or off in the 'Analysis Type' dialog. To do this, you must assign a displacement to the control joint for a particular DoF, where the control joint is free to move in that direction. If you were to use displacement control, bear in mind that it's only possible to have at most one for each LC.

    I am attaching some excerpts from S-FRAME's Internal Help System below. Feel free to review all the topics related to support settlements to learn more about this tool (menu bar, Help -> Contents -> Search tab, typing in 'Support Settlement', and selecting any of the related topics):
