Prioritization of seismic retrofit using scoring system
(New Zealand Society for Earthquake Engineering, 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?
(New Zealand Society for Earthquake Engineering, 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 ...
Implimenting the NZSEE Seismic Isolation Guidlines: a practioners view over three new designs
(New Zealand Society for Earthquake Engineering, 2020-04-22)
The draft seismic isolation guidelines provide a significant step forward in promoting a consistent NZ approach to designing and demonstrating compliance in isolated buildings. This paper provides a practitioners’ point ...
Real world investigation of seismic performance of buildings with hollowcore floors
(New Zealand Society for Earthquake Engineering, 2020-04-22)
The cyclic test on a super-assembly of hollowcore floor and frames at the University of Canterbury around 2003 revealed the seismic vulnerability of hollowcore floor practice at that time. Subsequent tests were conducted ...
Wellington's sedimentary basin and its role in amplifying earthquake ground motions: new CBD 3D model and maps
(New Zealand Society for Earthquake Engineering, 2020-04-22)
During the Mw7.8 Kaikōura earthquake, ground motions in central Wellington were clearly influenced by both the nature of the earthquake source and local amplification effects due to the sedimentary basin. These effects ...
The seismic performance of structural steel buildings in the 2010/2011 Christchurch Earthquake series and the 2016 Kaikoura earthquake: lessons learned, ongoing research and needs of industry
(New Zealand Society for Earthquake Engineering, 2020-04-22)
At least 20 earthquakes greater than Ms 7 have taken place in New Zealand since 1850. The recent earthquake that occurred in Kaikoura (Ms 7.8) is considered one of the largest earthquakes since 1855, but Christchurch's ...
Full-scale shaking table testing of a low-damage steel structure using Resilient Slip Friction Joint
(New Zealand Society for Earthquake Engineering, 2020-04-22)
The objective of this study is to give an overview of the design and numerical analyses related to a full-scale steel structure shaking table test that includes some structural applications of Resilient Slip Friction Joint ...
Slip rate variations on major strike-slip faults in central New Zealand and potential impacts on hazard estimation
(New Zealand Society for Earthquake Engineering, 2020-04-22)
Geological investigations over the last two decades have demonstrated that major strike-slip faults
in central New Zealand (e.g., Awatere, Clarence, Wellington faults) have experienced significant
millennial-scale variations ...
Numerical modelling of reinforced concrete walls with minimum vertical reinforcement contents
(New Zealand Society for Earthquake Engineering, 2020-04-22)
Reinforced concrete (RC) structural walls are effective lateral force-resisting components that are commonly implemented in tall buildings. Recent studies have investigated the impact of minimum vertical reinforcement ...
A pilot study on effectiveness of flow depth as sole intensity measure of tsunami damage potential
(New Zealand Society for Earthquake Engineering, 2020-04-22)
Current practices have commonly used tsunami flow depth as the sole hazard Intensity Measure (IM) in fragility functions underpinning tsunami damage, loss and risk assessments. Tsunami flow depth is often obtained from ...
