SESOC are actively seeking feedback on the current SESOC Interim Design Guidance v11, as we plan to update it again following the release of the finalised TS 1170.5 later this year.
If you believe there are sections of the draft guideline that could be improved, or if there is a design issue you believe would benefit from additional industry guidance please include details of this below.
The current SESOC Interim Design Guidance can be found here: https://www.sesoc.org.nz/design-resources/guidelines

A section on mass timber (or generally timber design beyond NZS 3604) could be added. This section would require coordination with the proposed joint standard AS/NZS 1720.1.

Please include the interpretation of NZS1170 in relation to accidental eccentricity, which was covered in the 2024 SESOC newsletter:
For nominally ductile and brittle structures the 0.1b accidental eccentricity provisions of Clause 5.3.2 are to be applied to the actions along the 100% orthogonal axis only and are to be applied in conjunction with the 30% perpendicular action applied through the nominal centre of mass for that direction (i.e. with zero eccentricity from that perpendicular action).
