Development and implications of an expanded national earthquake catalogue for New Zealand
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In the last two decades, New Zealand (NZ) has experienced significant earthquakes, including the 2010 M 7.2 Darfield, 2011 M 6.2 Christchurch, and 2016 M 7.8 Kaikōura events. Amongst these large events, tens of thousands ...
Monotonic and Cyclic Pushover Testing of Isolated Piles of the Whirokino Trestle
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In New Zealand, over 60% of State Highway bridges were designed and built during eras with low seismic provisions and most of these bridges are supported by pile foundations. An improved understanding of the in-service ...
Wellington basin amplification: research goals and update from the National Seismic Hazard Model Programme
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In Wellington, 3D basin amplification effects observed at 1 – 2 second spectral periods were identified as one factor likely to have exacerbated damage to mid-rise structures during the 2016 Mw 7.8 Kaikōura earthquake ...
Rapid, automated, post-earthquake building assessment using a swarm of drones and machine learning techniques
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Completing safety evaluations of buildings is critical for the health and safety of a city’s community following a damaging earthquake. Most contemporary post-earthquake evaluations involve groups of people who physically ...
The State of Practice in SSI Modelling in New Zealand: Insights from an Engineering Profession Survey
(New Zealand Society for Earthquake Engineering, 2021-04-14)
There is a relatively brief consideration for soil-structure interaction (SSI) effect in the New Zealand guidelines for the seismic assessment of structures. Recent earthquake events including the Kaikōura earthquake of ...
Evaluation of a geospatial liquefaction model using land damage data from the 2016 Kaikoura earthquake
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Earthquake induced liquefaction and lateral spreading can cause major damage to buildings and infrastructure networks. Common procedures to identify exposed areas such as cone penetration testing require extensive resources ...
Influence of remedial ground densification on seismic site amplification
(New Zealand Society for Earthquake Engineering, 2023-04-19)
While the capability of remedial ground densification techniques to mitigate the adverse effects of liquefaction has been widely investigated in recent decades, the characterization of ground motion amplification in the ...
Simplified approach to rapidly predict road blockages caused by co-seismic landslides
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The 2016 Kaikōura earthquake triggered tens of thousands of landslides leading to several road blockages which isolated the population in Kaikōura and disrupted the transport services across the South Island. The prediction ...
Using 3D geological models to create maps of estimated Vs30 and site period
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The 30-m time-averaged shear-wave velocity (Vs30) and the fundamental site period (T0) are useful parameters for understanding site conditions, informing geotechnical studies as well as infrastructure planning. Unfortunately, ...
Framework Development for a Hybrid Geotechnical-Geospatial Liquefaction Assessment Model
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Liquefaction assessment can be performed using various bodies of knowledge, each with an associated accuracy based on the data involved. Liquefaction assessment models based on directly measured subsurface geotechnical ...
