Site-specific seismic hazard analysis - evolving developments in practice
(2023-04-19)Site-specific hazard analyses (SSHAs) are undertaken to inform seismic actions for the design of important projects in New Zealand. These have typically adopted the 2010 National Seismic Hazard Model (NSHM) as the reference ... -
Finite Element Convergence Study of the Asymmetric Friction Connection (AFC) in the Optimised Sliding Hinge Joint (OSHJ)
(2023-04-19)The Optimised Sliding Hinge Joint (OSHJ) is a cost-effective, low damage seismic resisting beam-column connection developed for Moment Resisting Steel Framed (MRSF) buildings. The OSHJ is the optimised version of the ... -
A quantitative risk assessment of seismic slope stability for a tailings dam
(2023-04-19)Tailings are a by-product of mining, consisting of silts and sands from the processed rock or soils and susceptible to liquefaction under earthquakes. Tailings Storage Facilities (TSFs) include dams that are designed and ... -
Influence of remedial ground densification on seismic site amplification
(2023-04-19)While the capability of remedial ground densification techniques to mitigate the adverse effects of liquefaction has been widely investigated in recent decades, the characterization of ground motion amplification in the ... -
Accounting for the Influence of Intrinsic Soil Properties and State Variables on Liquefaction Triggering
(2023-04-19)Current simplified liquefaction triggering procedures are limited in their ability to capture the effects of intrinsic properties (grain size, mineralogy, grain shape, etc.) and the state properties (stress state, void ... -
Meet EDDIE – QuakeCoRE’s new earthquake test dummy
(2023-04-19)Until recently there has been limited understanding of the relationship between behaviour during earthquake shaking and risk of injury. Studying human behaviour during shaking is important, however, because with a better ... -
International alignment and update of the New Zealand earthquake intensity scale
(2023-04-19)The New Zealand Modified Mercalli intensity (MMI) scale was last revised in 2008. Even so, the scale's lack of specificity on New Zealand's structures for MMI>8 intensity levels has made it difficult to assign values for ... -
Seismic Behaviour of Slender Rectangular Reinforced Concrete Walls based on analytical methods
(2023-04-19)In the seismic design and assessment of structures, one of the key parameters is the displacement capacity of the structural elements. Slender reinforced concrete (RC) structural walls are one of the more commonly used ... -
Seismic design of an XblocPlus® revetment using multi-model approach
(2023-04-19)When designing and constructing revetments, there is often a drive to reduce the footprint due to space constraints and a limited supply of suitable rock armour materials. Concrete armour units present a potentially more ... -
Using holistic design to improve the seismic performance of non-structural elements and building resilience
(2023-04-19)Non-structural elements typically contribute around 80% of the total cost of a building. Damage to these components as well as works to repair and replace earthquake damaged non-structural elements can mean buildings are ... -
Displaced But Not Moved: Performance-Based Foundation Design
(2023-04-19)Improved understanding of seismicity within New Zealand and globally has led to an increase in seismic hazard for many locations. High seismic acceleration demands (e.g. >1g) for buildings and infrastructure have led to ... -
GeoNet’s Shaking Layer Tool: Generation of near-real time ground shaking for post-event response
(2023-04-19)Information on ground shaking following an earthquake is important for many applications from emergency response, engineering assessments, infrastructure management, insurance claim estimation and research. GeoNet, along ... -
Public expectations of damage and disruption to existing multi-storey buildings in earthquakes
(2023-04-19)The seismic performance of both structural and non-structural building components have the potential to affect the lives of building occupants, with poor performance likely to cause undue disruptions to the lives of building ... -
Elongating plastic hinge element for nonlinear analysis of RC structures using OPENSEES
(2023-04-19)During inelastic cyclic loading, the length of plastic hinges in reinforced concrete (RC) members increases irreversibly which significantly affects the seismic performance of RC structures. It is hence necessary for ... -
Enhancing earthquake and tsunami preparedness and response in Kura Kaupapa Māori/Schools in Tairāwhiti and Waiāriki, Aotearoa New Zealand
(2023-04-19)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 ... -
“Modal crimes” in structural engineering
(2023-04-19)With increasing seismic hazard as advised by the NSHM 2022 for entire New Zealand, there is a huge demand for the retrofit of existing building stock to achieve higher earthquake resilience. One of the ways to achieve a ... -
Experimental proof of the effectiveness of timber panels in the seismic retrofit of URM buildings
(2023-04-19)Recently there has been a growing interest by both academia and the industry in the possibility of using timber as a strengthening material for the seismic retrofit of unreinforced masonry (URM) buildings. This possibility ... -
Shake-table testing of resilient, low-cost seismic isolators based on rolling rubber spheres
(2023-04-19)This study presents the results of a large-scale experimental investigation of resilient, low-cost seismic isolators based on deformable rubber spheres. The isolators roll on flat or spherical (concave) concrete surfaces. ... -
Effect of Periodic Unit Cell Volume on Attenuation Zones of 1D-Meta-material based Periodic Foundations
(2023-04-19)The meta-material-based periodic foundations are being investigated by researchers for earthquake engineering applications due to their wave-filtering ability. The periodic foundations are characterized by frequency bandgaps, ... -
