• [TSD-10601] - Seismic Loading - Incorrect accidental torsion load

  This issue relates to seismic analysis and design for all Regional Codes that include the RSA analysis method. For models with a mix of rigid and other diaphragm types, the application of the accidental torsion loads in the seismic torsion load cases can be incorrect producing an unconservative reduction in the total applied torsion. The issue does not affect the ELF seismic analysis method. For more information please see Product Bulletin PBTSD-2209-1.

  • This issue is fixed in this release.

• [TSD-12127] - Seismic Loading - Amplification of accidental torsion not applied

  This issue relates to seismic loading calculations for all Regional Codes. In the following specific circumstances, the accidental torsion loads in the Seismic Torsion load cases were incorrect or not applied: 1) the lowest construction level was either empty or contained only a few entities within a bounding area << that of the floor diaphragm areas 2) the Seismic Wizard > Structure details setting “Ignore seismic in floor (and below)” was set = none (default) or to another level which was similarly empty or contained only a few entities 3) Levels with slabs and or roof items set to the Semi-rigid diaphragm option. The issue did not occur for levels with at least one slab item set to the Rigid diaphragm option (default). For more information please see Product Bulletin PBTSD-2208-1.

  • This issue is fixed in this release.

• [TSD-12246] - Concrete Beams & Columns - Analysis model not updated following changes to Assumed Cracked setting

  This issue relates to the analysis and design of models with concrete members for all Regional Codes. Following changes to the Assumed Cracked setting for concrete beams and columns, the modification factor appropriate to the change was not immediately applied to the applicable members in the analysis. Concrete walls were not affected. Since concrete walls were not affected and the Assume Cracked setting is conservatively set to Yes by default (fully cracked hence lowest stiffness), it is considered likely that in most cases the issue would lead to conservative results. However it is possible that it could result in an underestimate of intended member design forces in some cases. For more information please see Product Bulletin PBTSD-2209-2.

  • This issue is fixed in this release.

• [TSD-12338] - Composite Beams - No ignored forces warning issued

  This issue relates to the design of composite beams to all Regional codes. In general Tekla Structural Designer warns the engineer of significant forces from analysis that are not considered by design. For composite beams these are axial and minor axis bending and associated shear force. However in some circumstances no design warnings were issued for composite beams subject to such ignored forces. For more information please see Product Bulletin PBTSD-2210-1.

  • This issue is addressed in this release - ignored forces warnings are now issued appropriate to the Ignore forces Design settings for all combinations considered by design.

• [TSD-12431] - Concrete Column Design - US Regional Code - Incorrect effective depth for shear capacity

  This issue relates to the shear capacity checks for reinforced concrete columns with circular and polygonal type sections to the USA Regional code ACI 318 (all years). For these sections the calculated effective depth was larger than that recommended in the code, resulting in an overestimate of the shear capacity assumed in design. For more information please see Product Bulletin PBTSD-2210-2.

  • This issue is fixed in this release.

• A number of additional fixes which are not detailed explicitly here are also made to improve general performance and stability. An example of such an issue is given directly below.

  • [TSD-12215] - Crash (program exception) when right-clicking groups in Project Workspace

    A crash (program exception) could occur when right clicking on certain truss, brace, and portal frame branches of the Groups tree in the Groups Window of the Project Workspace. This is fixed in this release.

• [TSD-12255] - Section Database - Spanish Cold Rolled Sections added

  The following Spanish cold rolled sections have been added to the Europe sections of the materials database: Brausa Sigma Sections, Correas ACH C Sections, and Correas ACH Z Sections.
  

• [TSD-12100] - Foundation Mats - corrected representation in views

  Previously for levels set to TOS, mat foundations would be drawn in the same manner as slabs, with the bottom of the mat at the level. As a result, piles could appear to be disconnected from the foundation mat. This has been changed and foundation mats are now always drawn with their top surface at the level. BIM export/ import is also updated to follow this improvement.

• Remoting API Enhancements

  This release continues the rapid development of the Tekla Structural Designer Open API. For more about the API, see the Tekla Developer Center Get started with Tekla Structural Designer Open API.

  • Note that from the previous 2022 SP2 release and henceforth, the API is no longer part of the Tekla Structural Designer installation. The API package can now be downloaded from nuget.org, making it much easier for it to be included in your application and obtain future updates to the package.

  • The API examples on GitHub have been updated as follows:

    • The CreatingAndAnalyzingModel example now includes the creation of isolated foundations, as well as editing of steel beam and concrete column sections.

    • Example styles and package references have been updated.

    • The Extracting1DElementData has been updated to fix an issue in the output of section properties.

  • The following capabilities have been added to the Tekla Structural Designer Remoting API in this release:

    • [TSD-12216] - The Name property can now be extracted for any member span. Previously the Name was available for the full member, but not individual spans.

    • [TSD-11770] - Portal Frames can now be created, edited, and the data extracted via the API.

      • This includes data relating to all aspects of the portal frame including; Columns, Rafters, Haunches, Parapets and Ties.

      • Section and material properties for the above can be extracted, as well as required dimensions, among other properties

• [TSD-12082] - Trimble Connect - improved linking of report/ drawings to IFC model

  In some circumstances, when attempting to upload a drawing or report and link it to the associated member in the uploaded IFC model in a Trimble Connect Project, the file was uploaded but it was not linked to the member. Linking of reports/ drawings is improved to be more reliable in this release.

Reports

• [TSD-12137] - Seismic Design Report - amplified torsion result tables now always included for torsion Plan irregularities

  To give the engineer further information on and confidence in applied Seismic Wizard loads, when Plan irreg 1a - torsion or 1b - extreme torsion are specified on the Structure Irregularities page of the Seismic Wizard, the additional results tables for amplification of accidental torsion are now always included in the report. Previously the tables were only included when the calculated amplification factor A_x > 1.0 for at least one building direction.

  • when A_x ≤ 1.0 for both directions, an explanatory note is included below the tables confirming this and that no amplification is applied, as shown in the picture below.
    

• [TSD-12025] - Member End Forces for RSA Seismic Results

  The First and Second-Order RSA Seismic Analysis Methods are now available for selection for the Member End forces report item, enabling reporting of RSA Seismic case and combination results for members.

• [TSD-11325] - “Timber Design Forces” report item removed

  The content of the Analysis > “Timber Design Forces” report item pre-dated the introduction of the Tedds timber design link and as a result the forces reported were not compatible with the actual forces sent to the Tedds calculation. To avoid confusion this report item has been made obsolete. In this release, the item can no longer be added to new reports and you are advised to use the 'Member End Forces' report instead.

The number in brackets before an item denotes an internal reference number. This can be quoted to your local Support Department should further information on an item be required.
