A bespoke analytical methodology for seismic safety assessment of spillway gates: case study of Waipapa dam spillway on the Waikato River
(2022-04-27)This paper presents a seismic assessment methodology tailor-made for the Waipapa Dam Spillway gates on the Waikato River which were found to have potential dam safety issues under the 1 in 2500-year annual exceedance ... -
A case study of Soil-Foundation-Structure-Interaction for aseismic design of wind turbines
(2022-04-27)Wind farms in New Zealand have a combined capacity of about 690 MW and supply around 6% of New Zealand’s annual electricity generation. This is about the amount of electricity 300,000 kiwi homes use in a year. Wind farms ... -
A preliminary investigation of validity of conventional single-mode pushover analysis in multi-mode systems
(2022-04-27)Pushover analysis is a simplified inelastic analysis approach where a structure is subjected to increasing increments of monotonic imposed force or displacements to estimate the inelastic deformations in the structural ... -
A review of international guidance for tsunami loading on buildings
(2022-04-27)Tsunami loading on structures creates a potentially controlling structural demand that is less understood than other design loads. Guidance for tsunami loading scenarios is sparce, and there is a great deal of variation ... -
Advancing NZ Hospital seismic readiness: creating a post-earthquake functionality dashboard
(2022-04-27)Continued functionality of critical infrastructure systems, such as hospitals, shortly after an earthquake is expected. However, experience indicates that there may be some disruption due to damage, outages, or access that ... -
Application of resilient rocking cores in low damage mass timber structures: A case study
(2022-04-27)The application of mass timber structures made with massive wooden panels such as Cross Laminated Timber (CLT) has significantly increased in the last few years owing to their many architectural and structural advantages, ... -
Assessing the impact of acceleration-sensitive components on the seismic losses of multi-storey office buildings
(2022-04-27)The Ministry of Building, Innovation and Employment is developing advice on how to deliver Low Damage Seismic Design (LDSD) protection for buildings through their Tū Kahika: Building Resilience platform. A preliminary ... -
Code requirements for column confinement with a view on drift
(2022-04-27)Confinement provided by transverse reinforcement plays an essential role in reinforced concrete columns. When proportioned judiciously, confinement provides longitudinal bar restraint, contributes to shear resistance, and ... -
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 ...
