Seismic Isolation of bridges: Case Studies
(2022-04-27)Seismic isolation is one of the most effective means of earthquake hazard mitigation. Seismic isolation bearings are typically placed in a bridge between the substructure and superstructure and physically decouple the ... -
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 ... -
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, ... -
Sustainability in enhancing the resilience of major route in Wellington
(2022-04-27)Uncertainty in the seismicity of Wellington and climate change were key issues that influenced the design of strengthening of a key arterial route in Wellington. The abstract describes the innovations and technology adopted ... -
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, ... -
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 ... -
Seismic response of a base-isolated building under pulse-like near-fault ground motions
(2022-04-27)Pulse-Like Near-fault ground motions are known to challenge base-isolated buildings with their capacity to create large isolation system displacements. Such earthquake records typically contain velocity pulses with long ... -
Risk-targeted framework for seismic design: Maintaining serviceability
(2022-04-27)Changes to how seismic loads are determined for building design are imminent, as necessitated by the ongoing National Seismic Hazard Model update. The authors recently proposed a framework to produce risk-targeted hazard ... -
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 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 ... -
Shake Table Tests of a Six-Span Steel Bridge Model for Nonlinerality Identification
(2022-04-27)Most of real structures exhibit nonlinear behaviour during their lifetime. Nonlinear behaviour of a structure can be as a result of a local effect (friction in joints, joint and link flexibility, and nonlinear contact) or ... -
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 ... -
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 ... -
Seismic structural monitoring in Wellington using advanced seismological techniques
(2022-04-27)Sklodowska et al. (2021) employed advanced seismological techniques usually applied to Earth studies to the Te Puni building (instrumented as part of the GeoNet building instrumentation programme) for the 2009-2017 ... -
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 ... -
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 ... -
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 ... -
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 ... -
