Tekla Structural Designer 2016i Service Pack 4

Last updated November 20, 2017 by Tekla Structural Designer Development Team tekla-product-development-tsd-team-ug@trimble.com

Tekla Structural Designer 2016i Service Pack 4

This release will upgrade your Tekla Structural Designer 2016i installation to Tekla Structural Designer 2016i Service Pack 4 version number 16.1.4.94 and should be installed to ensure optimum function of the program.   It includes a number of enhancements and issue resolutions as detailed below (a number of more minor fixes are not listed).

If you are updating from a version earlier than Tekla Structural Designer 2016i SP3 (version 16.1.3.91) 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 Knowledage 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 2016i to be installed and will upgrade this to version 16.1.4.94
    • Previous Versions and file compatibility - Files from all earlier versions can be opened in Tekla Structural Designer 2016i Service Pack 4 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 in Tekla Structural Designer 2017 and retain the original.

Enhancements & Fixes

General & Modelling

  • Portal Frames - Editing - a program error could occur for some ‘miss’ frames containing valleys when attempting to edit the frame via the right-click context menu option (52999).
  • File Closing - a program error would occur when closing any file after viewing the details of the drift, seismic drift, or sway report for any column(s) (53010, 53073).
  • Slabs - a program error could occur when trying to create a slab in an inclined plane (53137).
  • Analysis Element - Material Type - a program error would occur when the Properties Window > Material Type was switched to Timber and the characteristic was set to analysis element (53038).

Validation

  • Analysis -  rarely, an erroneous Analysis element too short validation error could occur where no such short elements existed.   Validation routines are improved to prevent this occurrence (52967, 13711).

Analysis & Results

  • Analysis Process - Load Decomposition - rarely, for certain complex geometries, the load decomposition process could fail preventing the completion of analysis (13745).
  • Concrete Walls - Mid Pier - changes to wall extensions were not reflected in the self weight of the wall following analysis.  Since wall extensions are usually small the error in load would usually be minor.  The issue could be worked around by un-checking and re-checking the wall “use mid pier” property - this is no longer required (53212).

Design

General

  • Design Options - Design Forces - the setting Design Options > Design Forces > Concrete Beams > Torsion Force %... is now hidden when the Head code is set to other than Eurocode as it is only applicable to the Eurocode (52956).

Slab Design - Punching Checks - previously it was not possible to add a punching check onto a sloped slab - a program error would occur if this was attempted (53030).

Head Code Aus

  • Steel Design -  Portal Frames - the design process for portal frame columns could fail producing a design error status (13635).

Head Code BS

  • Steel Design
    • Combined Axial + Bending Check - for class 2 I sections the minor axis effective plastic modulus was underestimated by a small amount due to use of the flange thickness instead of web thickness in the calculation of b/T (53057).
    • Composite Beams - Slimflor sections - a Beyond scope Design status is now assigned to any composite beams using these sections.  Formerly an Unknown status was assigned.  This applies to other asymmetric sections which are beyond the current scope of composite design (52843).
    • Non-composite Beams - Slimflor sections - for major axis bending a “Not A Number” error would occur in the lateral torsional buckling (LTB) check for sections for which Iy (minor axis inertia) was > Ix (major axis inertia).  The check is now omitted in this circumstance since major axis LTB does  not occur where Iy > Ix - a message to this effect is issued  (52400).

Head Code EC

  • Concrete Design - Beams - the presentation of the equation for minimum number of link legs displayed in design details incorrectly omitted a “+1” at its end.  The equation displayed calculates the required number of spacings and hence the number of legs is the result + 1.  This issue affected only the equation displayed in the result details, not the result itself which is unchanged (13766).

Head Code US

  • Steel Design - Braces - Compression - where the Compression > Effective Length factor Kz value was edited to other than unity, this was not correctly reflected in the effective buckling length used in the axial compression - flexural torsional buckling check in which the full member length was still used (13739).

Reports & Drawings

  • Model Report - Report Contents - “View” chapter – if a View Configuration of a 2D view of a mat foundation was selected that included deflection contours, the deflection legend was omitted (13551).
  • Detail Drawings - Concrete Walls - in some circumstances the wall detailing drawing could fail to generate (13627, 13797).
