Last updated January 22, 2020 by Tekla Structural Designer Development Team tekla-product-development-tsd-team-ug@trimble.com

Tekla Structural Designer 2019i Service Pack 3

This release will upgrade your Tekla Structural Designer installation to version number 19.1.3.17 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 the previous release 2019i SP2 (version 19.1.2.16) you can find details of requirements, enhancements and fixes for 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.
    • License Server Version - for Server licenses, it is always our recommendation that you are running the latest version of the Tekla Structural License Service on your license server.  Please see System Requirements for specific version details. 
  • Installation - this service pack requires Tekla Structural Designer 2019i (version 19.1.0.86) to be installed.
    • 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. 

Issues with Associated Bulletins

  • [TSD-5674]1 - Seismic Combinations for RSA Seismic Analysis - the member end forces reported in some areas of the program could be incorrect.  Note that the issue does not affect any design checks carried out within TSD. For more information please see Product Bulletin Product Bulletin PBTSD-2001-1.
    • This issue is fixed in this release.
  • [TSD-5771]1 - Steel Angles as Columns or Posts - analysis results could be incorrect for steel members only in the following very specific circumstances:
    • The member section was a single angle.
    • The member characteristic was one of the following; Column, Gable Post or Parapet Post.
    • When the member was not set to be "continuously restrained"

We expect that these conditions existed in very few models and, even in the unusual case where it did apply the overall effect was likely to be negligible. For more information please see Product Bulletin Product Bulletin PBTSD-2001-2.

  • This issue is fixed in this release.

Enhancements & Fixes

Integration

  • [TSD-5289]1 - IDEA StatiCa interoperability - the link with IDEA StatiCa is now working with the latest version of IDEA StatiCa 10.1 (build 10.1.113). Earlier builds of IDEA StatiCa 10.1 may not be compatible. The previous compatibility with the latest versions of IDEA StatiCa 9.1 and 10.0 is retained.

General & Modeling

  • [TSD-4098]1 - Foundation Mats - to help prevent unintentional creation of unstable models it is no longer possible to set a mat foundation to be a semi-rigid diaphragm. It should be noted that when any slab/mat is meshed in the 3D analysis and the rigid diaphragm option is set to none, then it is inherently a semi-rigid diaphragm.
  • [TSD-5424]1, [TSD-5886]1 and [TSD-5933]1 - Connections - When connections are present in a model (after using the 'Update Connections' command) certain operations on the associated members would cause the program to crash. To avoid this, connections are now deleted under the following circumstances:
    • When members forming part of the connection are deleted.
    • When the member 'Characteristic is changed e.g. from 'Beam' to 'Column'.

As a consequence you will need to reinstate the connections after your member edits.

Performance

  • [TSD-5795]1 - Composite Beam Effective Widths - an enhancement has been made which significantly reduces the time to validate the effective widths of composite beams in some situations. The impact of this may be more significant on larger models.
 

Design

General

  • [TSD-5857]1 and [TSD-5870]1 - Steel Design - Presizing - performance improvements have been made for the presizing of steel columns during the autodesign process. As a further enhancement, the “Process” window now shows the percentage progress of the presizing stage, and the “Cancel” button in the bottom-left of the application window will now successfully abort the design process if it is pressed during the presizing stage.

Head Code US

  • [TSD-5626]1 - RC Column and Wall Design - effective length factor “k” - the equation for the calculation of the effective length factor in the design of unbraced reinforced concrete columns and walls to US design codes has been amended in accordance with ACI 318 guidance.
