Last updated January 17, 2018 by Tekla Structural Designer Development Team tekla-product-development-tsd-team-ug@trimble.com

Tekla Structural Designer 2017i Service Pack 2a

Important

This Service Pack is a replacement to Service Pack 2 therefore if you are not already aware of the content of Service Pack 2 please read the Service Pack 2 Release notes

This release will upgrade your installation to Tekla Structural Designer 2017i SP2a version number 17.1.2.75 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 most recent Tekla Structural Designer 2017i SP2 (version 17.1.2.74) you can find details of enhancements and fixes included in all previous releases in Tekla User Assistance (TUA) and Tekla Downloads.  You will find all the main releases listed in the Knowledge base area of TUA under Release notes while those for Service Packs can be found under Updates.  Links to release notes together with the version number can also be found in Tekla Downloads (login required).

Licensing & Installation

  • Licensing - no new license is required for this version.
  • Installation - this service pack requires Tekla Structural Designer 2017i to be installed and will upgrade this to version 17.1.2.75.
    • Previous Versions and file compatibility - Files from all previous versions can be opened in Tekla Structural Designer 2017i SP2a however note that once saved they cannot then be opened 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.
    • 32bit (x86) and 64bit (x64) Versions - Service packs are available for both 32bit (x86) and 64bit (x64) versions of Tekla Structural Designer.  Before downloading, check which version you have currently installed via the Information button at the top right of the Tekla Structural Designer window, then download the appropriate service pack

Enhancements & Fixes

Loading

  • Simple Wind - Loading Window - when the Loading Window was set as the currently active Project Workspace window, a program error would occur on opening for any model containing load cases which included Simple Wind loads.  In addition, for open models containing such load cases, the Loading Window would appear blank.  The file opening issue could be worked around by setting any other Project Workspace window to be the active window before opening the file (54251).
  • Decomposition - Panel Loads - Point Loads - an erroneous Decomposition Warning was issued “Some loads have not been applied > PL X lies outside of panels” for point loads which were legitimately within the panel area/ on the panel perimeter.  Such point loads loads were in fact applied.  The issue affected all types of panels to which point loads apply (54161, 14524).

Validation

  • Concrete Walls - Meshed Walls - for some geometries, due to a tolerance issue, walls with beams along their base (so called ‘supporting’ beams) could result in Member Collision validation errors.  This issue relates only to version 2017i first release (17.1.0.64 released Sept 2017)  - in which it was introduced - and its subsequent service packs to date (14357, 14434).
    • Note that, after installing this Service Pack, it is necessary to run the “Update Wall Beams” command (on the Analyze tab of the Ribbon) to remove the collision errors.  They should then not occur when the model is re-validated.
    • It is worth mentioning in relation to this issue that a meshed wall  - being formed of a mesh of 2D elements with in-plane stiffness in all directions - can act as a “deep beam”, supporting itself fully spanning between vertical support positions.   Hence a beam under a meshed wall may not actually support it to a significant degree.  Thus for all instances of meshed walls running on beams, we recommend the engineer consider carefully how they wish the arrangement to behave - if the engineer wishes the beam to fully support the the wall, we recommend it is of the Bearing type.  This wall type has only vertical stiffness and thus no deep beam action can occur*.  This validation issue did not occur for bearing walls.
      • *For more information on concrete wall types and their analysis model see the Help Topics; Engineer’s Handbooks > Analysis Handbook > Solver elements for concrete shear walls and Solver elements for bearing walls.
