Last updated October 10, 2018 by Tekla Structural Designer Development Team tekla-product-development-tsd-team-ug@trimble.com

Tekla Structural Designer 2018 Service Pack 5

This release will upgrade your Tekla Structural Designer installation to version number 18.0.5.04 and should be installed to ensure optimum function of the program.   It includes a number of enhancements and issue resolutions as detailed below. 

If you are upgrading from a version earlier than Tekla Structural Designer 2018 Service Pack 4 (version 18.0.4.9) you can find details of enhancements and fixes included in all previous releases in Tekla User Assistance (TUA) and Tekla Downloads via the links below:

Licensing & Installation

  • Licensing - no new license is required for this version.
  • Installation - this service pack requires Tekla Structural Designer 2018 to be installed and will upgrade this to version 18.0.5.04.
    • Previous Versions and file compatibility - Files from all previous versions can be opened in this release however note that, once saved, they may not open in an older version.  If you wish to retain this option we therefore recommend using the File > Save As… option to save a new version of the file and retain the original.

Fixes & Enhancements

General & Modeling

  • Performance and Stability - a number of fixes and enhancements are made to improve general program stability and performance.
  • BIM Integration:
    • Improved handling of Holes in Walls:
      • [TSD-1366]1 - IFC Export - holes were exported, but due to a defect for some models, they were not  located correctly and hence did not display after importing the IFC file into Tekla Structures or the Free Solibri Model Viewer for example.  Holes are now exported correctly.
      • [SRX14428]1 - Revit Integrator - an error in the export Wizard which prevented holes in walls from being exported correctly is now fixed.
    • [TSD-1384]1 - Walls - Copying - from 2018 SP1 (version 18.0.1.10 released in April 2018) and later service packs, using the Copy command on structural walls would have caused problems for BIM because the internal reference used for round-tripping was duplicated in error.  Other model objects were not affected in the same way.  Opening a model with duplicate references in this new release will generate unique references for each copy as well as preventing the problem occurring if the Copy command is used again.
  • [TSD-1364]1 - Wind View - a program error would occur when attempting to select a wind load case after switching to another Wind Direction when a load case for the previous direction was selected.  The workaround was to set the Load case drop list to “None” before changing the Wind Direction.  This issue relates only to version 2018 SP4 (18.0.4.9 released in August 2018) - in which it was introduced - and is fixed in this release.
  •   Materials Database - Shear Connectors - the following fixes are made for issues encountered when adding/ editing Shear Connectors:
    • [TSD-1428]1 - User-defined Connectors - a program error could occur on closing the Materials dialog after adding user-defined shear connectors to the database for British Standards Head Codes.
    • [TSD-1462]1 - User-defined Connectors - it was necessary to check on rather than check off the “Auto strength” in order to enter connector strength values when adding connectors.  This operation is now corrected such that the “Auto strength” is checked off in order to enter your own values.

Validation

  • [TSD-321]1 - Single Angles - a new Validation check and associated Warning is added for moment releases applied to beams with single angle sections to assist engineers with ensuring releases are applied as they intend - for more information see the Help Topic  Engineer's Handbooks > Analysis Handbook > Releases > Note on single angle releases.

Analysis & Results

  • [TSD-321]1 - Single Angles - the handling of moment member loads in the analysis of steel beams with single angle sections is addressed to correct the direction of load application and yield more expected results.  In addition, as noted above, a new Validation check and associated Warning is added for moment releases applied to such beams to assist engineers with ensuring releases are applied as they intend  - for more information see the Help Topic  Engineer's Handbooks > Analysis Handbook > Releases > Note on single angle releases.

Design

General

  • [TSD-525]1 - Concrete Design - Concrete Walls - Shear Links(Stirrups)  - an erroneous fail status and message “Supplied links/ stirrups are not sufficient” could be issued in design details where no shear reinforcement was required and the interactive design setting “Use links” was set to off.  This was caused by shear link spacing checks still being performed when not required.  It could be worked around by enabling “Use links”, setting a passing link spacing, then checking off “Use links” again. This issue is fixed in this release and the workaround is no longer required.

Head Code US

  • [TSD-161]1 - Concrete Slab/Mat Design - Punching checks - changes are made to the assumption of how the slab punching shear critical perimeters for circular and polygonal columns are obtained.  Where previously these were obtained by considering as the starting point the bounding rectangle of the column section, now a rectangle of equivalent perimeter length to the column section is used as the starting point. This results in a design which is both more conservative and in line with the design code assumptions.

Reports & Drawings

  • [TSD-1083]1 - Reports - Loading - Snow Loads - in models with Snow Load cases generated by the Snow Wizard, the report would fail to generate when the Loading item was included and the applied filter caused the inclusion of any of the generated Snow cases.  Hence it was not possible to output snow load case Loading data.  Generated Snow Load case data can now be included in report using the Loading item.
