Rupture model of a Hikurangi megathrust earthquake
We develop a multi-segment M8.6 rupture model of a Hikurangi megathrust event, including unilateral rupture with propagation towards the northeast, in accordance with Schellart and Rawlinson (2012). We use the Graves and ...
Planning Shake-Table Testing of a Three-Story Low-Damage Steel Frame Building
INTRODUCTION As part of QuakeCoRE research into the reparability of structures, the ROBUST (RObust BUilding SysTem) BUILDING SYSTEM TESTING programme is a collaborative NZ-Chinese project involving the 2-D shaking table ...
Alternative Data Sources for Impact-Based Forecasts and Warnings and Impact Modelling Risk Communication
Introduction Impact modelling and early warning systems play a key role in community resilience. Identifying the specific impacts of a hazard allows communities to adjust their behaviours and better prepare. Availability ...
Community Resilience Capital Framwork: A Critical Assessment based on a Waimakariri Case Study
1. INTRODUCTION. Earthquakes and geohazards, such as liquefaction, landslides and rock falls, constitute a major risk for New Zealand communities and can have devastating impacts as the Canterbury 2010/2011 experience ...
Post-Liquefaction behaviour of undisturbed and reconstituted natural pumiceous sands
Introduction Pumice particles, which originated from volcanic eruptions centred in the Taupo and Rotorua regions in the North Island, are frequently encountered in many engineering projects. These particles are then mixed ...
Preparing for the Big One
Introduction New Zealand is a signatory to the UNISDR Sendai Framework for Disaster Risk Reduction 2015-2030. The Framework sets out four priorities: the first involves understanding disaster risks across all dimensions ...
Shaking Table Tests of Full-Scale Rocking Selective Pallet Racks
Introduction A series of full-scale shaking table tests were conducted at the University of Auckland Structures Test Lab. Three complete structures were tested in the cross-aisle direction, each with a different baseplate ...
Reviwing Issues with Anchor Projects in Christchurch following the Earthquakes in 2010-2011
Introduction In 2011 Christchurch city centre was partially destroyed by an earthquake. Government-led anchor projects were tasked with bringing Christchurch back from rubble. After a period of 7 years out of 16 proposed ...
Rebuilding Christchurch: Amended Building Codes and their Impacts in NZ
The level of destruction from the 2011 Christchurch earthquakes led to changes in the New Zealand seismic building code. The destruction showed that the NZ building codes did not fully performed to expectation and needed ...
Probabilistic Framework for modeling spatially distributed infrastructure
THE CHALLENGE In risk analysis for spatially distributed infrastructure we must: Analyze system as a whole Account for spatial correlation Represent great uncertainty Keep computationally tractable
