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 ... -
Reclamation resilience improvement at CentrePort, Wellington New Zealand
(2022-04-27)CentrePort operations were significantly disrupted following damage to strategic assets sustained in the 2016 Kaikōura Earthquake, demonstrating the ports seismic vulnerability. Improved resilience is a necessity to long-term ... -
Repair and Reinstatement of Douglas-fir CLT Hold-down Connections using Mixed Angle Self Tapping Screws
(2022-04-27)The system ductility of timber structures under seismic loads relies on well detailed connection systems. With the increasing popularity of mass timber structures, CLT shear walls provide an efficient seismic load resisting ... -
Retaining Wall Design - SESOC
(2022-04-27)In the absence of a recognised or accepted national standard, and in order to provide clarity around the technical basis for their retaining wall software, some time ago SESOC embarked on the development of two design ... -
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 ... -
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 ... -
Seismic Performance of Precast Hollow-core Units Seated Within the Plastic Hinge Region
(2022-04-27)This paper discusses the susceptibility of hollow-core floor units to sustain a higher degree of damage when they are seated within the plastic hinge regions of the supporting beam. This damageability of these so-called ... -
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 ... -
Seismic retrofit of historic timber structures: Uncertainties and adaption on site
(2022-04-27)Existing timber structures, containing more hand-adapted and degradable components than other materials, provide challenges in ensuring your design intent is followed through on site. Often these buildings are flexible ... -
Seismic strengthening of the Seatoun Tunnel
(2022-04-27)The Seatoun tunnel is a 147m long, vehicle and pedestrian tunnel built in 1906-1907 to provide a tram connection between the suburb of Seatoun the city of Wellington. In 2011, the Seatoun tunnel structure was assessed as ... -
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 ... -
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 ... -
Social Influences on behavioural response to earthquake shaking
(2022-04-27)Many earthquake injuries in Aotearoa New Zealand occur because people either do not act quickly to protect themselves or act in a way which can lead to harm. Earthquakes are an uncertain context in which to make behavioural ...
