M. To add an enclosed zone load

To add an enclosed zone load to a primary load case, use the following procedure.

You must have an enclosed zone defined in order to add this load type to a load case.
Note: The following modeling tools are not supported in STAAD.Pro 2023 for models which have enclosed zones:
  • Mirror
  • Translational Repeat
  • Circular Repeat
  • Generate Rotate
  • Copy
  • Move Node
  • Move Origin
  1. Either:

    On the Loading ribbon tab, select the Load Items tool in the Loading Specifications group

    Tip: This will add the load item to the currently selected load group selected in the program status bar.

    or

    In the Load & Definition dialog, select a primary load case in the Load Cases Details list and then click Add.

    The Add New Load Items dialog opens.
  2. Select the Enclosed Zone > Enclosed Zone Load tab.
  3. Select the Zone Name from the drop-down list.
  4. Type the Intensity value. This is the magnitude of the load applied
    Tip: Negative values can be used to reverse the load application direction.
  5. Specify the Direction of load application:

    Local Z - apply the load perpendicular to the enclosed zone

    The load is applied using the "right-hand rule": if a enclosed zone boundary is defined by nodes in a counter-clockwise order, then a positive value loads in the positive local Z direction. Conversely, if a enclosed zone boundary is defined by nodes in a clockwise order, then a positive value loads in the negative local Z direction.

    or

    GX / GY / GZ - apply the load parallel to one of the global model axes

    This option represents a projected load along a global axes. This can be particular useful in applying wind or snow loads.

  6. Click Add.
  7. Repeat steps 2 through 4 to add additional enclosed zone loads to the current primary load case.
