International alignment and update of the New Zealand earthquake intensity scale
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The New Zealand Modified Mercalli intensity (MMI) scale was last revised in 2008. Even so, the scale's lack of specificity on New Zealand's structures for MMI>8 intensity levels has made it difficult to assign values for ...
Base isolated building preformance and the impact of the national seismic hazard model
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The NZSEE/MBIE recently released seismic design guidelines aiming to provide a more consistence design performance of base-isolated buildings in NZ. This paper confirms the superior performance of base-isolated buildings ...
Modelling of residential house perimeter foundation beams subjected to ground deformations
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The 2010-11 Canterbury earthquake sequence is the most damaging and disruptive seismic event to affect New Zealand, resulting in repair costs totalling approximately NZ$40 billion. Liquefaction induced ground deformations ...
Method for the explicit consideration of ground motion duration in NZS 1170.5
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Recent studies have demonstrated that longer earthquake ground motion duration can reduce structural deformation capacity and increase collapse risk. This study introduces a method to explicitly account for such effects ...
