Modify Structural Attributes Classic

Used to modify Structural member attributes quickly by populating its settings by persisting the user defined settings rather than populating them with values taken from the selected members. This increases productivity by having the Modify Structural Attributes (Classic) tool remember previously applied changes that can be repeatedly applied until changed explicitly. It increases productivity by "remembering" previously applied changes that can be repeatedly applied until changed explicitly.



The Modify Structural Attributes (Classic) tool is accessible only via key-in.

SettingDescription
General tab Contains controls for modifying the selected member or members physical attributes such as section data and member orientation.
  • Section — Used to enter a new section definition for the selected member or members. Clicking the magnifying glass icon opens the Structural Sections dialog. From here, section definitions are browsed.
  • Tapered — When on, two section data options are enabled to modify tapered members; One for end 1 and the other for end 2.
  • Section 2 — Used to enter a new second section definition for the selected tapered member or members. Clicking the magnifying glass icon opens the Structural Sections dialog. From here, section definitions are browsed.
  • Fillets — When on, fillets are constructed between the flange and web surfaces on the selected structural member or members.
  • Placement Point — Modifies the location of the baseline relative to the member section by selecting from the drop list items. The Centroid placement point is enabled only if the section is fully symmetric (wide flange I beam) or if the section properties include a valid centroid.


    Equivalent illustration of Placement Point options

    The active placement point is marked with an arrow.
  • Local Y Offset — Used to modify the physical member's placement points in the Y axis direction.
  • Local Z Offset — Used to modify the physical member's placement points in the Z axis direction.
  • Rotation Angle — Used to modify the selected structural member or members by either entering a new angle or interactively with data points.
    • Interactive – Modifies the rotation angle by entering a data point to spin members about their member line axes as the cursor moves around the screen.
  • Mirror — When on, constructs an identical member type of the selected structural member or members, but in a mirror-image/flipped orientation.
Data tab


Contains controls for modifying the selected member or members Structural Data attributes such as Structural type, class, material grade as well as user defined attributes.
  • Mark — Used to enter a new identification mark for the selected structural member or members (for instance, C1 for beam, B1 for beam).
  • Type — Used to enter a new Structural member type attribute for the selected structural member or members (for instance, Beam, Column, Deck).
  • Material — Used to enter a new material attribute for the selected structural member or members (for instance, Steel, Concrete, Timber).
  • Grade — Used to enter a new grade attribute for the material type of the selected structural member or members (for instance, A36 for Steel, 4000psi for Concrete).
  • Status — Used to enter a new status for the selected structural member or members (for instance, New or Old)
  • User1–4 — Used to modify the four available user definable Structural attributes for the selected structural member or members. The reactions are used to identify or translate member data with external applications.
  • Class — Used to enter a new class or component order for the selected structural member or members (for instance, Primary, Secondary, Framing)
  • End1/End2 Action — Used to enter new end reactions for each end of the selected structural member or members (for instance, 12K)
  • End1/End2 Detail — Used to enter new end details for each end of the selected structural member or members (for instance, Type I, Type II)
Analytical Information tab


Contains controls for modifying the selected member or members Structural Analytical attributes such as analytical line location, type and end releases.
  • Analytical Line Location — Used to modify the line location that determines where the analytical member will be drawn.
    • At placement points - When selected, the assigned placement location of the selected member or members analytical lines is changed to the placement points of the physical member.
    • At centroid - When selected, the assigned placement location of the selected member or members analytical lines is changed to their centroid axes.
  • Type — Used to modify the analytical member type for selected member or members to be used for the analytical modeling purposes (not the physical model member).
    • Beam – When selected, changes the selected member or members to analytical beams and applies flexural and/or axial stresses.
    • Truss – When selected, changes the selected member or members to analytical trusses and applies tension or compression stresses.
  • End Releases — Used to modify selected member or members end releases. When on, end 1 and end 2 Releases controls are enabled, but only for analytical beam member types. For analytical truss member types, the end release values are automatically overridden and preset. End releases determine the support/boundary condition for the nodes in the analytical model.
    • Releases End 1 (i)/Releases End 2 (j) – When on, modifies the releases at end 1 and end 2 of the selected member or members.
      • X/Y/Z – When on, changes the restriction for linear movement of the nodes in the X, Y, and Z directions.
      • RX/RY/RZ – When on, changes the restriction for rotational movement of the nodes in the X, Y, and Z directions.
Design Parameters tab


Contains controls for modifying the selected member or members Design Parameters attributes before exporting to STAAD.Pro via ISM. The specific design parameters are dependent on which design code or standard is chosen. When a design code is chosen, the associated parameters are initialized with default values.
