[TSD-13563] - Metal Decking Database - New ComFlor® 51+ Metal Deck profile added

Tata ComFlor® 51+ data has been added to version 11 of the metal decking database for Europe, UK and Ireland. Note the older Corus Comflor 51 and Tegral Comflor 51 are both retained in the metal decking database.

[TSD-14459] - Steel Sections Database - New US AISC sections added

The AISC steel sections database is updated to include the new shapes introduced by the 16th version of AISC's official section shapes database. The AISC shapes database v16.0 has added 222 new sections for US steel design - 6 W, 6 WT, and 210 HSS (64 circular, 127 rectangular, and 19 round).

[TSD-15718] - Masonry Walls - wall masonry properties added to edit dialog

For Masonry walls (first introduced in release 2024) the individual wall edit dialog now includes all the masonry properties as shown in the picture below. In the previous release these properties were only available in the Properties Window for a selected wall.

[TSD-15995] - Review view - Slab/ Foundation Reinforcement view enhanced

[TSD-15903] - Tooltip display time extended

Tooltips displayed when the cursor is over a ribbon command now remain visible up to a maximum of 60 seconds by default, while the cursor is not moved. The previous default display time of 5 seconds was not always sufficient to read and digest some of the tooltips.

[TSD-15889] - Unable to open files created with Education License in previous versions

An issue introduced in the first release of version 2024 which prevented files produced with an Educational License in previous versions being opened is fixed in this release.

[TSD-15739] - Member loads - Option to adjust load position when it becomes invalid

When the loading segment of a member changes, this can cause member loads to be moved beyond the end of the member, which causes a model geometry error. This may typically happen when an exterior concrete column size is increased, affecting member loads on a supported beam. Since member loads are positioned relative to the start of the loaded length, if the member load is already at the very end of the loaded length, an increase in column size can shorten the loaded length and "push" the load, or part of it, off the end of the member, causing it to be invalid and producing a validation error. To more easily resolve such cases, new “Reposition”and “Shorten” options have been added to the right-click menu for the error in the Status tree, as shown in the picture below.

• The options work as follows:

  • Reposition - applicable to both distributed and point loads

    • Point loads - are moved back to the end of the beam.

    • Distributed loads - the length of load is retained and the start position changed so it is fully on the beam.

  • Shorten - applicable only to distributed loads - the start position is maintained and the length changed.

Reference Models For the Reference Models feature (introduced in release 2024) the following improvements are made in this release:

• [TSD-15946] - Reference models at real world coordinates

  When the origin of a reference model uses real world coordinates (RWCs) it may be at a very different location to the model origin in Tekla Structural Designer. In these circumstances it can be challenging to determine the transformation required to position the reference model correctly in Tekla Structural Designer . To help with this, the Edit Reference Model dialog now shows the range of coordinates included in the reference model enabling you to more easily determine the required transformation coordinates.

  • Import from other model - for the case of multiple reference models all of which reference the same RWCs, the "Import from other model" option enables the re-use of the Coordinate Transformation values of a previously imported model.

    

• [TSD-1593] - Zoom considers visible reference models

  Visible reference models are now considered in zooming to the full extent of the model, using the view cube and general model rotation.

Remoting API Enhancements

There have been some enhancements to the Open API with this release - for information about these see the Tekla Structural Designer 2024 Open API Release Notes page.

[TSD-14969] - RSA Results - consistent sign notation

Response Spectrum Analysis results which involve Modal Combination are unsigned hence are both positive (+ve) and negative (-ve). In previous releases the order of sign notation used in the Results View was different to that of the Tabular Data view reports, with -ve/+ve used for the former and +ve/-ve for the latter, which could lead to confusion. This is corrected in this release with a consistent order of -ve/+ve now used in all areas of RSA results reporting.

[TSD-15919] - Piled mat slab - incorrect reaction for chasedown analyses

Only for the situation of a pile located directly under a column - such that the pile support node and column bottom node were common - double counting of forces in the process of calculating chasedown results for combinations resulted in the combination reaction being incorrect and too high. Thus the issue would always be conservative. This issue is fixed in this release.

[TSD-13460, 16042] - Composite beams - Connector Resistance warning for deformation capacity

For the AISC 360/ 341 2016 code year for beams > 30 ft span with degree of shear connection < 50%, the Connector Resistance check warning for stud connector deformation capacity per the Commentary on I3.2d.1 is changed from being based on the average shear connector group spacing of 12in as suggested, to being based on the alternative of the average nominal shear connector capacity (in terms of kpf). Where the warning could previously be frequently issued this should no longer be the case.

Masonry Wall Design using Tekla Tedds

• [TSD-16066] - Export to Tedds - improved Project Manager organization

  When exporting the results for several walls to Tedds to produce a Project of several Tedds design documents, these are now more logically organized in the Tedds Project Manager, using a Model > Wall > Panel > Result line hierarchy, similarly to results of concrete wall designs.

Wood Design Using Tekla Tedds Improvements

The following improvements to Wood Design Using Tekla Tedds are made in this release:

• [TSD-15579] - Multiple plies solution retained after check

  When designing a wood member using Wood Design Using Tekla Tedds and selecting a solution of multiple plies e.g. three plies of 1-3/4" x 18" LVL, this solution is now retained when the member is re-designed or checked using Tekla Tedds. Previously on re-design or check, multiple plies were changed to a single equivalent section e.g. (3) 1-3/4" x 18" LVL were changed to a single 5-1/4" x 18" LVL section.

• [TSD-15357] - Correct section size and name returned

  When using US customary units and selecting a section size such as 19.75 in depth and breadth glulam in the Tedds Wood Member design calculation, the correct “19.75” section size is now returned to the Tekla Structural Designer model. Previously a section size such as “19.74999999996” was returned leading to problems with section names in the Tekla Structural Designer model and with section mapping when using BIM workflows.

[TSD-15743] - RC Beam Design - equation for additional link reinforcement for torsion adjusted

The equation to calculate the area of required link reinforcement over spacing for torsion in the design of RC beams to EN 1992-1-1 has been amended in this release in order to remove some conservatism, in line with general guidance. Previously the equation included a 0.9 factor in the denominator - this is removed in this release.

[TSD-15585] - Improved operation of Model Filter

In some instances, the items returned when a Model Filter was applied to a Tabular Data View report table did not match those returned when the same filter was applied to a report. The operation of filters is improved in this release such that the returned items for Tabular Data Views and Reports for the same model filter now match.
