M. To assign axial action members

To assign a member as compression-only, tension-only, or a truss (axial-only) member, use the following procedure.

STAAD.Pro allows you to specify the axial actions of members.
注記: This assigns the analytical specification for truss members. For the purpose of Connection Design, you must additionally assign a Truss attribute.
  1. (オプション) Select the members which will all have the same member specification assigned.
  2. On the Specification ribbon tab, select the Beam tool in the Specification group.

    A list of member specification types opens.
  3. Select the specification type you want to assign:

    Compression Only – members are capable of carrying compression forces only


    Tension Only – members are capable of carrying tensile forces only


    Truss – members are capable of carrying axial forces only

    注記: These member specifications have no additional parameters.
    The Member Specification dialog opens to the corresponding tab.
  4. Either:
    To… Do the following…
    add the specification to the model and assign to the current member selection click Assign.
    add the specification to the model for later assignment click Add.
    The dialog closes.
The member specification is added to the Specifications - Whole Structure dialog and the Specification Values table.
