Development and implications of an expanded national earthquake catalogue for New Zealand
Hutchinson, Jesse; Lee, Robin; Bradley, Brendon; Van Houtte, Chris; Kaiser, Anna; Wotherspoon, Liam (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 ... -
Evaluation of a geospatial liquefaction model using land damage data from the 2016 Kaikoura earthquake
Lin, Amelia; Wotherspoon, Liam; Motha, Jason (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 ... -
Monotonic and Cyclic Pushover Testing of Isolated Piles of the Whirokino Trestle
Chigullapally, Pavan; Hogan, Lucas; Wotherspoon, Liam (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 ... -
Rapid, automated, post-earthquake building assessment using a swarm of drones and machine learning techniques
del Rey Castillo, Enrique; Zhou, Yang; Liarokapis, Minas; Yang, Xiaofei; Wang, Feng; Walsh, Kevin; Wotherspoon, Liam; Ingham, Jason (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
Hnat, Theo; McGann, Christopher; Wotherspoon, Liam (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 ... -
Wellington basin amplification: research goals and update from the National Seismic Hazard Model Programme
Kaiser, Anna; Hill, Matt; Wotherspoon, Liam; Bradley, Brendon; Lee, Robin; Roten, Daniel; Bourguignon, Sandra; Pancha, Aasha; Gerstenberger, Matt (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 ...
