Proposed Material Requirements for Category 3 Members in Seismic-Resisting Systems

Proposed Material Requirements for Category 3 Members in Seismic-Resisting Systems - Call for Comment

Presenters:

Alistair Fussell, SCNZ Consultant

Kevin Cowie, Steel Construction New Zealand Inc, Senior Structural Engineer 

Dr Michail Karpenko, General Manager - HERA Welding Centre

Abstract

This complimentary 1 hour Live webinar will provide important steel updates for all practicing structural engineers.

The current Category 3 steel member material requirements are considered overly onerous and, as a consequence, unnecessarily limit the range of compliant products, particularly for columns in seismic-resisting systems.

In collaboration with HERA and Dr Charles Clifton (University of Auckland), SCNZ has developed proposed category 3 steel material selection criteria for inclusion in the Steel Structures Standard (NZS 3404). The requirements are presented in Steel Advisor article MAT 2002, “Proposed Material Requirements for Category 3 Members in Seismic-Resisting Systems” which can be downloaded from the SCNZ website. These draft provisions are based on those in NZS 3404.1:2009 and the material selection methodology presented in a recent paper by Hobbacher and Karpenko (2020) entitled “Provisions for avoiding brittle fracture in steels used in Australasia”.

The presentation will cover the proposed category 3 member material selection criteria, their technical basis and the potential benefits of adopting these requirements. SCNZ is seeking feedback on the proposed material selection criteria. 

Date and time:

Wednesday 21st October, 3pm – 4pm
