Review View - Design Status Enhancements

There is a growing emphasis on mitigating the Carbon Impact of design and construction, so we have been focusing on new and improved features to assist engineers with this. For more about this and existing features related to it, see the Help Topic Measuring the carbon impact of a structure. This emphasis has led to a renewed focus on efficiency of design in terms of minimizing material usage - and thus maximizing utilization - rather than on reduction of direct construction costs through rationalization of sections/ details, potentially at the expense of some increased material and reduced utilization efficiency.

For a detailed discussion of this topic, please see for example this paper from the UK Institute of Structural Engineering: Rationalisation versus optimisation – getting the balance right in changing times, by Ian Poole.

Enhancements are made in the Tekla Structural Designer 2020 SP6 release to assist the engineer in assessing the efficiency of their design in these terms. These go hand in hand with the enhancements to Material listing information also made in this release. Improvements are made to the Review View > Design Status functionality, with the Legends being made more informative and the addition of new viewing filters. Together we believe these enhancements will make the Design Status view even more effective, allowing the engineer to remove ‘clutter’ and, for example, to focus on objects with low utilization so they can improve the efficiency of their design. For more information see the new Help Topic Design review filters.

  • These enhancements apply principally to the Status and Ratio views for: Member Design, Foundations, Piles, Slab/Mat Design, Connections.

    • Note however that the filters can also be used in the Review View with no Ribbon buttons selected.

  • Legend - when the Status view is active, the total number of entities with each design status is now given adjacent to each color group in the Legend as shown in the picture below. This highlights that Fails/ Warnings exist, even when the failing entities may be obscured in the current view - the engineer can then adjust the view to find where they occur. This is also the case for the (Utilization) Ratio view - the total number of entities in each ratio band is shown in brackets adjacent to the band legend color.

    Note: For the count of entities with each status, each span/stack/panel of continuous beams/columns/walls respectively counts as one entity. So, for example, if all stacks of a four-stack continuous column are failing, then this will contribute 4 to the count of failing entities.
  • New Filters - the following new Review View filters are now available and are accessed via the Properties window: Status, Utilization ratio, Entity type.

    • These allow the engineer to show/ emphasize in the active view only entities that comply with the filter settings.

      • By default, with the “Ghost excluded” general setting enabled, other entities are ghosted, as shown in the picture below right, making the location of filtered entities in the model clear. With “Ghost excluded” disabled, excluded entities are removed entirely from the view.

    • By default, with the “Manual filters” general setting disabled, when the Status or Utilization ratio Ribbon buttons are selected, only the associated Status/ Utilization ratio filters are automatically listed in the Properties window.

      • You can see all the filters simultaneously by enabling the “Manual filters” setting - you then check the “Active” box to enable each set of filters you require as shown below left.

  • The filters can be used individually or in combination and allow the engineer to focus on specific results, typically for status/utilization displays - for example the picture below shows simultaneous use of the Utilization ratio (UR) and Entity type filters, with “Ghost excluded” off, to see only members with a low UR (below 0.3).

    • Note also the number of entities listed for each band in brackets adjacent to the Legend band color as mentioned above - so in this example we know there are 12 entities with UR between 0.2 and 0.3, and 42 between 0 and 0.2
