Development of an expanded earthquake and ground motion catalogue for New Zealand
(2021)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 ... -
Experimental loading protocols to evaluate the seismic performance of floor systems
(New Zealand Society for Earthquake Engineering, 2021)Major earthquakes, such as the Canterbury and Kaikoura events recorded in New Zealand in 2010 and 2016 respectively, highlighted that floor systems can be heavily damaged. At a reduced or full scale, quasi-static ... -
Full waveform seismic tomography for geological velocity model in Canterbury region based on adjoint-wavefield method

The China-NZ ROBUST Friction Building Shaking Table Testing Overview
(2020)Shaking table testing of a full-scale three storey resilient and reparable complete composite steel framed building system is being conducted. The building incorporates a number of interchangeable seismic resisting systems ... -
Application of genetic algorithms to select a ground motion set for conducting HC-IDA
(2020)This paper describes the application of genetic algorithms to select a generic set of ground motions that can be used to conduct hazard-consistent incremental dynamic analysis (HC-IDA) on a wide range of structures located ... -
Centroid moment tensor inversions using 3-D Green’s tensor and adjoint methods for earthquakes included in full waveform tomography for the South Island region, New Zealand [poster]
(Southern California Earthquake Center, 2020)In this poster, we determine centroid moment tensor (CMT) solutions by two different approaches: iterative inversion based on the adjoint-wavefield method and direct inversion from the strain Green’s tensor and observed ... -
Cybershake NZ v19.5: New Zealand simulation-based probabilistic seismic hazard analysis
(2020)This paper presents a concise summary of the computational workflow and results of the May 2019 version (v19.5) of probabilistic seismic hazard analysis (PSHA) in New Zealand based on physics based ground motion simulations ... -
Cybershake NZ v19.5: New Zealand simulation-based probabilistic seismic hazard analysis
(2019)This poster presents the computational workflow and results of the May 2019 version (v19.5) of probabilistic seismic hazard analysis (PSHA) in New Zealand (NZ) based on physics-based ground motion simulations (‘Cybershake ... -
Finite element analyses of hollow-core units subjected to shear and torsion
(2021)A building boom in the 1980s allowed pre-stressed hollow-core floor construction to be widely adopted in New Zealand, even though the behaviour of these prefabricated elements within buildings was still uncertain. ... -
Strength requirements for non-structural components responding nonlinearly under earthquake excitation
(2021)This study develops a practice-oriented method to design non-structural components and their restraints to lower strengths than needed to remain elastic under earthquake ground motion by permitting nonlinear non-structural ... -
Seismic design and analysis of a medium-density residential building
(2021)There is an increasing recognition that good seismic performance requires not only checks on life safety but also limitation of damage, disruption and losses. In light of this, several proposals are currently being developed ... -
Full waveform tomography for the upper South Island region, New Zealand
(2021)In this paper, we apply Full Waveform Tomography (FWT) based on the Adjoint-Wavefield (AW) method to iteratively invert an existing 3-D geophysical velocity model for the upper South Island region, New Zealand. Through ... -
Modelling soil heterogeneity and wave scattering in geotechnical site response analysis
(2020)This study incorporates soil heterogeneity into geotechnical site response analysis to model wave scattering and the spatial variability of earthquake ground motion -
Ground motion simulation validation with explicit uncertainty incorporation for small-magnitude earthquakes
(2021)This study investigates the uncertainty of simulated earthquake ground motions for smallmagnitude events (Mw 3.5 – 5) in Canterbury, New Zealand. 148 events were simulated with specified uncertainties in: event magnitude, ...
