To apply a distributed moment on a member

To assign a uniform moment along a member or part of a member, use the following procedure.

  1. Select the members that will all have the same distributed load applied.
  2. On the Member ribbon tab, select the Distributed Moment tool in the Loads group.

    The Add Member Distributed Moment dialog opens.
  3. Select the Load group or case to which the load will be added from the drop-down list.
  4. Select the Moment type fro the drop-down list.
    • Uniform - a moment which is constant in magnitude along the entire member length
    • Partial - a moment which is constant in magnitude over a portion of the member length
    • Ends - a moment that is applied at a set distance from each end of the member
  5. Select the Direction in which the load acts from the drop-down list.
    • Global X / Y / Z – to apply loads parallel to the selected global axis.
    • Local x / y / z – to apply loads parallel to the selected local axis. Local x loads are axial to a member.
    • Projected X / Y / Z – indicate the loads along the projected length of the member in the corresponding global direction
  6. Enter the load values and distances per the Moment type selection:
    1. Type the moment magnitude.
    2. (Optional) For Partial or Ends moment types, set the As a percentage option to enter load distances as a fraction of the member length.
    3. For Partial or Ends moment types, type the distance to the loaded portion of the member:
      For… Type the…
      Partial Initial distance – distance from the start node to the start of the uniform moment.
      Ends Distance from end – distance from the start and end nodes of the loaded portion of the member.
    4. For Partial moment type, type the Final distance. This is the distance from the start node to the end of the uniform moment.
  7. Click OK. The dialog closes and the load is applied to the selected members.

You can edit distributed moment values for the current load group or load case by selecting the Disributed moments tool in the Member group on the Spreadsheet ribbon tab.
