Earthquake design for uncertainty Seminar (NSHM)

Earthquake Engineering in the context of the 2022
National Seismic Hazard Model (NSHM) Revision
hosted in joint collaboration with SESOC, NZSEE and NZGS.

Seminar coverage
This broad programme of work includes developing proposals to revise Building Code Verification Methods for new design work. It also includes ongoing support of the Earthquake-Prone Building system and management of risks across our existing building stock. The 2022 NSHM is an important step forward in our understanding of earthquakes and is one of many inputs into this work. The collaborating technical societies (SESOC, NZSEE and NZGS) have produced the Interim Advice on the 2022 NSHM Release, and a more comprehensive advisory on Earthquake Design for Uncertainty. These concepts, their application in practice, and the wider Seismic Risk Work Programme is the focus of this seminar.

Speaker Bio's

Professor Ken Elwood | MBIE-EQC Chief Engineer (Building Resilience) / Professor of Earthquake Engineering/Department of Civil and Environmental Engineering – University of Auckland

Ken joined the University of Auckland in 2014 after 11 years on faculty at the University of British Columbia, Canada. After experiencing the Christchurch Earthquake first-hand, Ken was drawn to New Zealand to pursue the numerous opportunities for research and implementation in earthquake risk reduction in the wake of the earthquakes. He served as the inaugural Director of Te Hiranga Rū QuakeCoRE: Centre for Earthquake Resilience. Ken started a new phase in his career in November 2021 through a multi-year secondment to the New Zealand Government to serve as the MBIE/EQC Chief Engineer (Building Resilience). Through this role, Ken champions the resilience of New Zealand’s built environment, by establishing strong stakeholder connections and promoting collaboration between relevant research, policy, and practice players.

Andrew Thompson | Technical Director, Holmes NZ

Andy Thompson is part of Holmes NZ’s Buildings/Structures team, based in Tāmaki Makaurau Auckland. His role encompasses project delivery, technical leadership/advancement, and leading of Holmes’ competence development programme. He has a simple passion for good engineering design that makes sense and is understood. Andy has served on the NZSEE management committee since 2019. His contributions have included inputs into the recent advisories and 2022 NSHM release guidance for engineers that form part of the content of these seminars. He currently represents NZSEE on the Joint Committee for Seismic
Assessment of Existing Buildings (JCSAEB) and is a member of the Steel Structures Standard P3404 revision committee.

Mark Willard | Principal Advisor-Engineering | Ministry of Education

Mark is an engineering advisor at Te Tāhuhu o te Mātauranga|Ministry of Education. He provides technical leadership and oversight of the Ministry’s seismic resilience policies, technical design guidelines for new school building design and ongoing work to improve the resilience of existing school buildings. In his role, Mark chairs the Ministry of Educations Engineering Strategy Group, which includes some of New Zealand’s leading structural and geotechnical engineers and is at the forefront of upcoming engineering issues, particularly issues that are relevant to large property portfolio owners and developers. Mark is a Chartered Structural Engineer (CMEngNZ, CPEng, IntPE(NZ)) and prior to joining the Ministry worked in a multi-disciplinary engineering consulting firm. Mark is based in Ōtautahi Christchurch.
