Dealing with uncertainty in prediction of lateral spread
(2022-04-27)Prediction of lateral spread for seismic assessment and design includes considerable uncertainty. Two widely used prediction methods are Youd et al. (2002) and Zhang et al. (2004). Five case studies across the Wellington ... -
Depth and Shape of the Basement Surface Beneath Wellington City, Based on Gravity and Seismic Constraints
(2022-04-27)A new basin-depth map for the Wellington Central Business District shows a maximum depth of 540 m near the Wellington Stadium. This is twice that previously proposed. Our new basin geometry constraints are from a residual ... -
Ductile timber connections: Understanding the factors contributing to their ductility
(2022-04-27)It is well accepted that ductility in a timber structure is achieved through its conections as the behaviour of timber is inherently brittle. It is thus important to understand the diferent parameters that contribute to ... -
Ductility factor validation for CLT walls with bolted hold-downs: preliminary analysis and observations
(2022-04-27)High-capacity cantilever CLT walls can be created with bolted hold-downs to resist earthquake loading. This study briefly presents the experimental results and cyclic behaviour of the representative test specimen. Then ... -
Earthquake Design Loads on Retaining Walls
(2022-04-27)Free-standing retaining walls are usually designed for earthquake loads using the Monobe-Okabe method and assuming cohesionless soil backfill. This simple design approach has led to satisfactory performance and is supported ... -
Elastic Design (μ=1.0) of Damage Avoidance Structures
(2022-04-27)Damage Avoidance Design (DAD) has been considered an efficient way for seismic design. Different solutions to achieve a robust DAD structure has been proposed and tested by researchers in the past. However, there is a lack ... -
Enhancing earthquake and tsunami preparedness and response in Kura Kaupapa Māori/Schools Aotearoa New Zealand: learnings from the 5 March 2021 East Cape earthquake sequence
(2022-04-27)Aotearoa New Zealand is exposed to numerous potentially damaging impacts from various hazard events. The east coast of the North Island, one of the most active seismic regions in New Zealand, faces significant earthquake ... -
Experimental and analytical evaluation of different failure modes of self-centring braces
(2022-04-27)As resilience of structures during seismic events is currently a main structural engineering topic, Low-damage self-centring braces have the potential to serve this purpose by becoming a common low-damage lateral load ... -
Geotechnical challenges and design solutions for Yarrow Stadium redevelopment
(2022-04-27)New Plymouth Yarrow Stadium’s two grandstands were declared earthquake-prone and closed in 2017-2018. The $50m repair and refurbishment project was approved in 2019 and subsequently reviewed and modified to allow for the ... -
Integrating Maori Perspectives into Community Resilience Frameworks for the Built Environment
(2022-04-27)Many governments and organisations have attempted to construct frameworks for improving community resilience, particularly as related to the built environment. Many frameworks take a large overview of society and miss the ... -
Interim Results from empirical ground motion model evaluation for the NZ National Seismic Hazard Model Update
(2022-04-27)As a part of the ongoing 2022 NZ National Seismic Hazard Model (NSHM) Update, the predictive capabilities of candidate empirical ground motion models are evaluated to ascertain models which provide good prediction for NZ ... -
Investigation of influential factors on yield strength of lead rubber bearings
(2022-04-27)The design of seismic isolators as specified by building code requirements is well defined and well established. However, there is still some refinement required for these design practices, especially in terms of estimating ... -
Liquefaction potential of sand-gravel mixtures: experimental observations
(2022-04-27)Case histories from at least 27 earthquakes worldwide (including three from New Zealand: 1929 Mw7.6 Murchison earthquake; 2010 Mw 7.1 Darfield earthquake; and 2016 Mw 7.8 Kaikoura earthquake) have indicated that liquefaction ... -
Mainstreaming building code practice and risk management principles towards disaster risk reduction
(2022-04-27)Global disaster impacts on the built environment have triggered the call for an operational disaster risk reduction (DRR). The application of building code requirements has shown an acceptable means of minimizing disaster ... -
Mechanical Anchor Supplementary Shear Reinforcing as a Retrofit Technique for Hollowcore Floors
(2022-04-27)Hollowcore floor systems have been prevalent in New Zealand construction since the 1980s. The susceptibility of these elements to fail under seismic action has been highlighted through numerous post-earthquake observations, ... -
Modelling the out-of-plane buckling behaviour of BRBFs
(2022-04-27)The objective of this study is to assess the impact of modelling the out-of-plane buckling behaviour of buckling-restrained braced frames (BRBFs) on their estimated seismic performance. A number of recent studies have ... -
Modelling uncertainty induced by plastic hinge length in lumped-plasticity analysis of RC columns
(2022-04-27)This study quantifies the influence of various plastic hinge length assumptions on the uncertainty in the response of reinforced concrete (RC) columns simulated using lumped plasticity models. Although several expressions ... -
Monitoring technologies to manage landslide risk to transportation routes in the Lower North Island
(2022-04-27)There is significant uncertainty in predicting the behaviour of slopes due to natural processes and events. The inherent variability in rock and soil make the use of precedent behavior a much more attractive tool. However, ... -
Post-earthquake functional recovery: A critical review
(2022-04-27)Functional recovery not only transforms the retrofit of damaged buildings from an earthquake event but also contributes to community resilience. This paper aims to provide a state-of-the-art literature review of functional ... -
Prediction of Demands on Non-Structural Components in Base-Isolated Structures
(2022-04-27)This study examines seismic demands imposed on non-structural components within base isolated structures. Although several previous studies have focussed on the ability of base isolators to limit structural damage, very ...
