STAAD PRO - ELASTIC FOOTING PROBLEM

Hello,

When running the analysis for a concrete plate supported on elastic supports and a nodal load in the center of it, the following "error" appears:

Does anybody know what is wrong?

Thank you in advance,

  • The error is due to the fact that the two numbers after the command ELASTIC FOOTING has been entered as 0 0 whereas this is supposed to represent the length and width of the elastic footing. A sample is shown next

    1 TO 6 ELASTIC FOOTING 1 1 DIRECT Y SUBGRADE 150

    In the above example a size of 1 ft x 1 ft is considered as the size. For multiple nodes this size would be based on the distance between the nodes. The direction would also be Y as opposed to X.

    Having mentioned that, when you are modeling the mat with a mesh of plates, you need to use PLATE MAT support instead.
