Wāhine tapuhi ō te parawhenua mea kia mataara- Wāhine-led, community-based research on earthquake resilience
(2020-04-22)Despite increasing attention on the importance of earthquake risk reduction for Aotearoa New Zealand communities, there are limited Māori-medium resources available, and more representation of Māori wāhine (women) researchers ... -
Seismic response of half-scale seven-storey RC systems with torsional irregularities: blind prediction
(2020-04-22)Past earthquakes have highlighted vulnerabilities to damage or collapse of building structures due to torsional response. While methodologies to capture torsional demand due to strength and stiffness irregularities have ... -
Developing guidelines for the seismic assessment of glazing systems
(2020-04-22)There is an increasing recognition that the seismic performance of buildings will be affected by the behaviour of both structural and non-structural elements. In light of this, work has been progressing at the University ... -
Design scenarios for piles in ground subject to liquefaction
(2020-04-22)Seismic shaking and liquefaction with its associated loss of soil strength and ground movements/deformations can be damaging to buildings and their foundations. Understanding ground behaviours and soil-structure interaction ... -
Shear Wall Design Tool - Structural Engineering Design Society NZ (SESOC)
(2020-04-22)SESOC has, over a period of time, developed and acquired a number of structural software design programs. This paper will preview a new development, namely “Gen-Wall”, a software program developed specifically for the ... -
The Scott Base redevelopment: Ross Sea geological hazards
(2020-04-22)To inform Scott Base development planning, we discuss the effects of historical earthquakes, tsunamis and volcanism on Antarctica and then focus on assessing the potential hazard from future tsunamis in the Ross Sea region. ... -
Influence of failure mode uncertainty on the collapse capacity of RC components
(2020-04-22)Acceptance criteria for reinforced concrete components are selected based on the assumption that the failure mode of a component is deterministic. This paper makes a case suggesting that such an assumption may be untrue ... -
Earthquake-resilience of storage tanks: using an innovative anchorage system
(2020-04-22)In this study, a new anchorage system has been introduced by employing the recently developed Resilient Slip Friction Dampers (RSFDs) as ductile self-centring hold-downs for liquid storage tanks. This new anchorage mechanism ... -
Element exchange search algorithm for optimal placement of viscous dampers for building structures
(2020-04-22)Optimal design of supplemental dampers efficiently enhances the seismic performance of structures. Existing methods of optimal damper placement design either require a large amount of iteration or can only reliably arrive ... -
Self-centring bracing system: avoidance of elastic buckling for braces with one intermediate damper
(2020-04-22)Today, more attention is being given to timber material by practitioners as a structural member owing to benefits that this material can offer such as high strength to weight ratio, being environmentally friendly and ... -
Mitigation of liquefaction induced lateral spread using jet grout shear walls
(2020-04-22)The load transfer mechanism between ground subject to liquefaction induced lateral spreading and jet grout shear walls is complex. The shear walls comprise rows of jet grout columns, constructed in a primary-secondary ... -
EQRNet: New Zealand's densest urban seismic monitoring network
(2020-04-22)An ultra-dense urban earthquake monitoring and effects management system is presented. We describe our learnings from the 2016 M 7.8 Kaikōura earthquake and how these motivated us to create a globally unique system of ... -
Geotechnical outputs from the EQC – Quake Centre Industry Fellowship programme
(2020-04-22)The Earthquake Commission (EQC) has, for a long time, been an important investor in high quality research in New Zealand. EQC’s research programme spans science, engineering and social science and has played a vital role ... -
Correlation between standard penetration test and shear-wave velocity in Wellington, New Zealand
(2020-04-22)The New Zealand standard NZS1170.5:2004 (amendment 1; Sep 2016; Earthquake actions) recommends seven methods for the determination of site classification as defined in Section 3.1.3.1. The most preferable method is direct ... -
A study of current research achievements and challenges on the application of High Strength Steel (HSS) endplates in seismic resisting systems
(2020-04-22)High strength steel is increasing in demand due to economic and mechanical benefits. A typical mechanical characteristic of HSS is that the ductility of the material decreases along with the increase in strength. This has ... -
Seismic base isolation of high-rise RC shear wall building using lead core rubber bearings
(2020-04-22)The use of base isolation technique is an effective way to control the seismic demands in buildings. The RC shear wall buildings represent the typical high-rise construction in several parts of the world. The seismic story ... -
Influence of ground motion orientation on predicted seismic compression
(2020-04-22)Seismic compression is the accrual of contractive volumetric strain in unsaturated or partially saturated sandy soils during earthquake shaking and has caused significant distress to overlying and nearby structures. The ... -
Earthquake prone building policy implementation in Lower Hutt
(2020-04-22)Lower Hutt building stock dates back to early nineteenth century, with the majority of older buildings concentrated in central business district and around historic precincts in Jackson Street. Inevitably, buildings built ... -
Prioritization of seismic retrofit using scoring system
(2020-04-22)As the research and engineering communities advance in their understanding of earthquakes and the associated effects, it becomes apparent that retrofit of old structures is necessary in order to protect the lives and assets ... -
How would changes to serviceability limit state design criteria impact likely repair costs?
(2020-04-22)The earthquake engineering community is currently grappling with the need to improve the post-earthquake reparability of buildings. As part of this, proposals exist to change design criteria for the serviceability limit ...
