Manage, display and design result lines

You can place user-defined result lines across 2D element meshes. For these lines, Tekla Structural Designer determines the force and moment results from the shell/plate/membrane nodal analysis results. These results can then be used to assess design solutions, (typically for the design of concrete or masonry wall panels with openings).

Engineering judgement is required when positioning the lines to ensure suitable design forces are obtained.

Create result lines

  1. Open a 2D view containing the meshed wall or slab within which you want to place the strip.
  2. In the Status bar, click Results View.
    The Results toolbar opens.
  3. In the 2D Integrated Results group, click Result Line.
  4. Click the start point of the line.
  5. Click the end point of the line.
    Tip: Neither the start or the end point have to match nodes in the mesh.

    Tekla Structural Designer creates a result line between the selected points.

  6. Do one of the following:
    • Continue placing further result lines.
    • Press Esc to exit the command.

View the analysis results for result lines

Note: An analysis must be performed after adding or editing result lines in order to obtain up to date results.
To view the results, do the following:
  1. Open a view containing the result lines whose results you want to view.
  2. In the Status bar, click Results View.

    The Results toolbar opens.

  3. Set the analysis type and loading for viewing analysis results.
  4. In the 2D Integrated Results group, click Result Lines, then from the droplist in the same group, select the desired result.
  5. From the droplist in the 2D Integrated Results group, select the effect that you want to view.
  6. From the Text group select Forces to display values on the diagram.

    Tekla Structural Designer displays the selected result on the result line.

    Note: All forces in the results are rotated to be in the axis system of the result line.
    Tip: If you are working in a 2D view and you can't see any results, try displaying the view in isometric projection.

Interactively design result lines in a concrete wall panel

  1. Open a view containing the concrete wall panel result line to be designed.
  2. Hover the mouse pointer over the result line.

    The Select Entity tooltip appears.

  3. In the Select Entity tooltip, navigate to the result line (RL) name by using the arrow keys.
  4. Right-click the result line.
  5. In the context menu, select Interactive Design... (as a column section, or as a wall section as required).

    The selected (column or wall) interactive design dialog is displayed with the Additional Design Cases page populated with the result line results.

  6. Modify the reinforcement parameters as required to achieve a satisfactory design, and click the Check button to examine the detailed design results.
  7. Click OK to save the designed reinforcement to the result line.
    Note: For help on using the interactive dialogs, see Interactive concrete column design and Interactive concrete wall design.

Features of concrete wall panel result line design

  • The interactive design dialog features full interactive manual selection of both lateral and vertical reinforcement, interaction diagrams and auto-design and check options, just as for a regular wall/ column section interactive design.
  • The wall length/ column depth considered is the Result Line length.
  • Result lines are not constrained to cross sections in the horizontal plane - vertical sections can be used above/between openings to investigate forces and reinforcement requirements in “coupling beams”.
    • The section design always considers the main bars (running perpendicular to the cross section) as being on the inner layer, from a design perspective this will tend to be conservative but the engineer should give this some consideration when working with non-horizontal sections.
    • The design does not consider the existing reinforcement specified in wall properties - only that which is defined in the Interactive design dialog.
    • Currently this feature is not linked with Reports and so it is envisaged output will be via screenshots of the interactive design and check results dialogs.
  • The same result line can be used to interactively design as a column, and as a wall. Both designs are saved to the result line independently.

Interactively design result lines in a masonry wall panel

Note: When a masonry panel result line is investigated in this way, none of the updated data (reinforcement size, spacing etc.) can be transferred back to the masonry wall panel. Instead, the preferred workflow (as described in the Masonry wall design handbook), would be to create a masonry wall patch, so that when the design is performed the updated reinforcement can be automatically transferred back to the wall panel if required.
  1. Open a view containing the masonry wall panel result line to be designed. For masonry design the result line has to be horizontal.
  2. Hover the mouse pointer over the result line.

    The Select Entity tooltip appears, listing all entities under the mouse pointer.

  3. If multiple entities are listed, use the arrow keys to select the result line (RL) name.
  4. Right-click to display the context menu.
  5. In the context menu, select Interactive Design... > Design using Tekla Tedds

    Tekla Structural Designer opens the Tekla Tedds masonry wall section design calculation to allow the section defined by the result line to be designed for forces at that section.

  6. Modify the reinforcement parameters as required to achieve a satisfactory design.
  7. Click Finish to close the Tekla Tedds design calculation.

Delete result lines

Tip: To delete a result line, ensure that Result Lines are switched on in Scene Content.
  1. Open a view containing the result line that you want to delete.
  2. In the Quick Access Toolbar, click Delete.
  3. In the model, click the result line that you want to delete.

    Tekla Structural Designer deletes the selected result line.

Result line properties

Select a result line and then use the Properties window to view and modify their properties.

General
Name The automatically generated name for the result line.
User Name Can be used to override the automatically generated name if required.
Type Wall or Slab.
Associated Entity The wall panel, or slab item associated with the result line.
Start

​X/Y offsets from a reference point in the plane of the item.

(Editable)
End

​X/Y offsets from a reference point in the plane of the item.

(Editable)
Length The “physical length” between the start and end points above.

(Not editable)
Result Length The total “result length” as calculated during last analysis model preparation.

(Not editable)

Note: The “result length” will often be the same as the "physical length" but in some circumstances could be shorter or longer:
  • If a wall has an extension and the result line continues into it, the "result length" doesn't include the length in the extension.
  • If a result line is drawn randomly between any two points in a wall
    • When the FE mesh is generated these insertion points are unlikely to lie on the edges of shell elements.
    • At each end the result line end is determined by either lengthening or shortening the physical line so that it ends on the closest available edge of a shell element.
