RAM Structural System Help

Pressure Load Properties dialog

Used to define pressure loads that are assigned to walls in the structure.

Opens when either:
  • PropTable > Lateral Loads > Wall Pressure Loads is selected
  • the Wall Pressure Loads tool is selected from the Layout Loads dynamic toolbar

Note: This tool may only be accessed in Elevation mode.
SettingDescription
Label Type a label used to identify the load for application.
Magnitude Select the method of specifying the pressure magnitude:
  • Pressure - specify the Top Pressure and Bottom Pressure on used. This allows a linear pressure gradient vertically on a wall. If the pressure is uniform, these values will be the same.
  • Inertia Force, fraction of g - specify a ratio of gravity, g, to use for the pressure. This is typically used for applying seismic loads.
Direction Select the direction in which the pressure acts.
  • Towards Primary Face
  • Away from Primary Face
Note: The primary face of a wall is dispalyed in the elevation mode.
pressure loads table This table includes all lateral pressure loads defined in the model.
Add Click to add the specified values to a new load.
Delete Click to delete the currently selected load in the table. If the load is assigned in the model, a warning is displayed an the load is not deleted.
Change Click to update the currently selected load in
