P. To display base pressure results

To display soil pressure at support node locations for slabs consisting of plate elements which have been generated using elastic mat or plate mat commands, use the following procedure.

This feature is only available for analyzed models that include these mat support conditions.
  1. Select the Layouts > Base Pressure tool in the View Results group on the Results ribbon tab. The vertical pressure value at each support node is displayed. The Base Pressure has tabs to display the pressure values at each supported node for all load cases, along with a summary tab.
    Tip: You may need to zoom in to see individual labels for some models.
  2. (Optional) Select a different Load in the View Results group on the Results ribbon tab. The labels update to reflect the base pressure for the selected load case.
