• [TSD-11514] - Analysis Results - potentially incorrect results for members in rigid diaphragms with member loads applied

  This issue relates to the analysis results for members within rigid diaphragms. As part of the load analysis post-processing in rare circumstances member loads applied to beams, truss top/bottom members, steel joists, or analysis elements could be incorrectly ignored or double-counted. For more information please see Product Bulletin PBTSD-2303-01.

  • This issue is fixed in this release.

• [TSD-12211] - Seismic Analysis & Design - All Regional Codes - Incorrect Effective seismic structure mass/ weight

  In the following specific circumstances, the automatically calculated Effective seismic structure mass (seismic weight for US code) was incorrect and too low; 1) One or more columns and/ or walls were supported by transfer beams or a transfer slabs which in turn were supported directly by a supports in the model at the transfer level AND 2) this transfer level was not set in the Seismic Wizard as the level for “Ignore seismic in floor (and below)”. This could result in lower and hence unconservative seismic base shear and seismic lateral loading. For more information please see Product Bulletin PBTSD-2303-02.

  • This issue is addressed in this release as follows:

    • Validation now checks for no level being set to be ignored in the Seismic Wizard and a warning is issued when this is the case, since this is not recommended. The warning is issued in both the Status Validation tree and in the Seismic Wizard adjacent to the entry box for this. Both warnings have cursor tooltips giving more information about the issue as shown in the picture below. A similar warning is also issued if a level is set and there are supports in a level above it.
      
      

      • Mat Foundation slabs - the requirement in the Seismic Wizard that the level to be ignored must be set to that of the mat foundation slab(s) (or the top such level when there are mat foundation slabs on more than one level) is removed.

      • For the circumstance of columns and/ or walls being supported by transfer beams or transfer slabs which in turn are supported directly by manually applied individual supports, the seismic mass/ weight is now correct.

        • Note however that two circumstances remain in which the seismic mass/ weight may still be incorrect. See the Product bulletin for more details of these.

• A number of additional fixes which are not detailed explicitly here are also made in this release to improve general performance and stability.

• [TSD-13407] - IDEA StatiCa Export - error on export fixed

  An issue introduced in release 2022 SP4 which prevented the export from working is fixed in this release.

General

• [TSD-11985, 13314] - Design Section Order - no need to specify when not required

  An issue was introduced in release 2022 SP4 preventing the specification of member types that are not designed directly in the program (such as purlins or plated members for some characteristics) without also specifying a design section order for them. This has been addressed in this release and design section orders are no longer required in such instances.

Eurocode

• [TSD-244] - Punching Shear checks - Slabs, Pad Bases and Pile Caps - revised column loaded perimeter length

  Column punching shear checks for slabs, pad bases and pile caps have been revised to automatically take account of the upper limit on column loaded perimeter length for the cases of edge and corner columns, as prescribed in EN1992-1-1 Clause 6.4.5(3). The new limit is imposed before any further user reductions are considered.

  • In previous releases to comply with the upper limit it was necessary to calculate the limit value yourself and specify an appropriate user reduction in the punching check Properties window as previously advised under the "User perimeter reductions" heading in the Punching shear perimeters Help Topic Section. This is no longer necessary following the enhancement in this release.

  • The revised method does not apply to wall, pile and column drop loaded perimeters.

ACI/AISC United States

• [TSD-13256] - Composite Beam Design - incorrect change of characteristic to non-composite fixed.

  The following issue introduced in release 2022 SP4 is fixed in this release; when the option “Attempt non-composite if auto composite solution fails” (previously titled, “Allow non-composite design”) was enabled and a check run, if the beam was not valid for composite design (e.g. was not pin ended or was subject to uplift), the beam characteristic would incorrectly change to non-composite. This change of member characteristic no longer occurs in this circumstance in this release.

  • [TSD-13015] - “Structure” Chapter - Export to Excel enabled

    The Structure chapter (and all its sub chapters) can now be exported to Excel. In previous releases, while the Excel export option could be selected this produced an empty sheet.
