Minor Enhancements and Fixes

General & Modeling

  • A number of additional fixes which are not detailed explicitly here are also made to improve general performance and stability.

  • Steel Section Database - Nordic Countries - some missing sections are added for both steel and cold formed materials to the section databases of Norway, Finland and Sweden. Additionally we have:

    • [TSD-5898-9] - some missing sections are added for both steel and cold formed materials to the section databases of Norway, Finland and Sweden.

    • [TSD-5906] - the naming of plated sections is changed to use the * symbol instead of lower-case x.

    • [TSD-4501] - new sections are added to existing order files.

    • [TSD-5551] - Section and order file defaults are updated to use only commonly available ones.

  • [TSD-5224] - Properties Window - the note window at the bottom of the Properties window will now auto size to display the full text of the property where formerly this could be truncated.

BIM Integration

  • Structural BIM Import
    • [TSD-4014] - for imported concrete models, the Autodesign member property for concrete 1D elements is now considered as follows:

      • When importing a CXL file into a new model file, the Autodesign member property is checked ON (previously it was OFF).

      • If importing a CXL file into an existing model, the current member autodesign property is retained irrespective of the value in the CXL file.

    • [TSD-4337, 4338] - a new UDA entitled Pour phases has been added to allow pour phase value to be passed between Tekla Structures and Tekla Structural Designer for concrete elements. The UDA is created on import where Pour Phase attribute exists in the CXL file.

      • Existing Pour phase UDA’s are checked on import and the BIM Status tree will list messages for any updated Pour phase UDA’s.

  • [TSD-2965] - Tekla Structures/ Revit Export - for transfer columns (e.g. a column supported on a beam) the misleading warning for analysis forces at bottom of column not including additional moment - issued in the BIM > Structural BIM Export status tree - is removed (as it applies only for column splice loads).

  • [TSD-2756] - Structural BIM Integration (CXL) File - the CXL file data structure is enhanced to include member fabrication, slab deck types and wall types:

    • On export from TSD, concrete members will be assigned a fabrication type.

    • On import to TSD if Other Data is ON in the import wizard, the fabrication/deck type will be updated as appropriate. Associated messages are shown in the BIM status tree.

Performance

  • [TSD-6075] - Graphics - the graphics driver settings in Home > Settings > Scene > Graphics are updated and adjusted.

  • DirectX is now called DirectX (old)

  • DirectX V2 is now called DirectX

  • DirectX (old) is based on DirectX 9 and is becoming obsolete while the new DirectX is based in DirectX 11 and is currently the primary HOOPS driver for 3D acceleration.
    • For existing installations (which will carry forward old settings) we recommend that the Driver setting is checked and set to the Auto option if necessary, as continuing with Direct X (old) could impair performance and stability.

    • To check your adapter’s compatibility visit the HOOPS developer website for HOOPS 20.x, DirectX and OpenGL requirements.
  • The “Auto” setting will let HOOPS pick the best driver (and is now the default)

  • [TSD-5870] - Design Process- the Process window now reports the progress % of the Presizing stage of autodesign (for steel members). The Cancel button can also now be selected during this process to terminate design.

Loading

  • [TSD-6200] - Loading Ribbon - buttons on the loading ribbon have been reorganized to keep the most commonly used items at large size as the application window size or screen resolution is adjusted.

    • “Load Groups” is moved after Combination.

    • “Panel Loads” re-ordered to promote the use of “Level” load when appropriate.

    • “Point” load moved to the left.

    • The redundant word “Load” is removed from each button.

  • [TSD-4017] - Load Combination Generator - US Head Code - the default service factors for dead loads in the combinations ASD-1.0D and LRFD-1.4D have been changed from 0 to 1.0.

    • The previous default value of zero, if not corrected, would produce incorrect beyond scope status for isolated foundation design where these combinations were generated and active. This issue should no longer occur.

  • [TSD-5827] - Perimeter Load - previously the Perimeter Load command could only be used provided that the 'create as line loads' option was checked on in the load properties. This has now been corrected.

  • [TSD-6004] - Temperature Loads - Slabs - temperature loading applied to slabs set as semi-rigid diaphragms was not applied if the diaphragm mesh type was also changed to be triangular (not the default). Temperature loads are now applied to semi-rigid diaphragms for any mesh type selection.

  • [TSD-6154] - Seismic Loading - US Head Code - for Seismic Loading to ASCE7-16, the revised capping provision for short period regular structures per Section 12.8.1.3 is now applied for building meeting all requirements of the clause with SDS < 1.0 using the actual SDS value. Previously in this circumstance SDS = 1.0 was used, resulting in over-conservative seismic loads.

Validation

  • [TSD-5795] - Composite beams - the validation time for models containing composite beams (of their effective widths) is considerably reduced.

  • [TSD-5459] - Wind Wall Panels - Decompose to Diaphragms - an additional model validation check is now performed to check the validity of area loads applied to wind panels that have been set to decompose to rigid diaphragms. For such panels the load can only be decomposed provided that it has been applied perpendicular to the plane of the panel. If the load is acting in any other direction a validation warning "Wind wall load beyond scope" is now issued.

Analysis & Results

  • Vibration Analysis renamed to “Modal” Analysis - in many regions, the term “vibration analysis” is more commonly associated with the perceptible vertical movement of floors (such as is checked by the DG11 Floor Vibration Check for example) or lateral sway of tall building subjected to service wind load, and the term “modal analysis’ is used to refer to an analysis which determines vibration modes and their properties (such as period etc). Hence the term “vibration analysis” is replaced by “modal analysis” in all instances within the program, such as in the Seismic Wizard and on the Analyze Ribbon as shown below.

  • [TSD-6382] - 2D Results - imposed load reductions are now implemented for meshed concrete wall Fy (vertical force) 2D contour values and the associated vertical stresses σy etc. Click the “Reduce Axial Force” toggle button in the Results View to see the results with imposed load reductions applied.

Design - General

  • [TSD-6248] - Timber Design using Tedds Link - design forces sent to the Tedds Timber design calculation now include the maximum forces of only active load combinations. Previously, maximum values considering load combinations, load cases and envelopes were used causing conservative design results in some scenarios.

Design - Head Code US

  • [TSD-5445] - Steel Joist Design - when a steel grade other than 50 ksi is applied to steel joists, the design will now details now issue a warning stating that the design assumes steel grade 50 ksi as shown below.

Reports

  • [TSD-5219] - Punching Checks - the “Report for Member” option is added to the right-click context menu for a selected punching check, allowing the engineer to produce an individual report for a punching check object.

  • [TSD-5224] - Material Listing - the Cold formed table now includes a column for the total number of cold formed members for each grade and the total.

  • [TSD-6052] - Portal Frames - Wind Drift Table - in the Wind Drift table of Review View > Tabular Data and the associated Report item, Portal frame columns are now given a unique reference which includes the Portal Frame reference for example “PF F/1-F/3 Span 1 Rh Column” rather than just “Span 1 Rh Column”.

  • [TSD-5797] - Report List - the Report Styles in new and existing models are now listed in alphabetical order. This also applies to the Member Type list in the Member Reports dialog. With this new feature, user-defined reports can be listed in a grouped order by careful prefixing.

  • [TSD-4991, 6010] - 2D Result Diagrams & Views - in some circumstances, reports including analysis diagrams of 2D contour results would not display the contours correctly. This issue has now been corrected.
