Outlook for earthquake early warning for Aotearoa New Zealand: Insights from initiating a community-of-practice
(New Zealand Society for Earthquake Engineering, 2021-04-14)
A community-of-practice (CoP) is a community that comprises of members that build relationships with each other to create technical advancements motivated by shared goals. Establishing communities-of-practice has been ...
Evaluation of the ShakeOut earthquake drill and use of protective actions in Aotearoa New Zealand
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Many earthquake injuries in Aotearoa New Zealand result from people falling or being struck by flying objects during shaking. Since 2012, the ShakeOut earthquake (and now tsunami) drill has aimed to teach the protective ...
Source modelling insights from ground motion simulation validation of moderate magnitude active shallow crustal earthquakes in New Zealand
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Hybrid broadband ground motion simulation validation has been an ongoing effort in NZ with recent studies focussed on active shallow crustal earthquakes of large magnitude (Mw>7.0) and small magnitude (3.5<Mw≤5.0). Lessons ...
Application of the Geotechnical Step-Change Provisions of the 2017 MBIE Guidelines for the Seismic Assessment of Buildings
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The Seismic Assessment of Existing Buildings, Technical Guidelines for Engineering Assessments (“the Guidelines”) provides engineers with a consistent means to assess the seismic behaviour of existing buildings with respect ...
Assessment of boundary conditions for 2D geotechnical site-response analysis with soil heterogeneity
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This paper examines various boundary condition assumptions for modelling 2D geotechnical site response, which requires a more sophisticated treatment of the boundary and loading conditions than what is typically required ...
Developing LSN-based pipe repair rate functions utilising data from the 2011 Canterbury earthquakes
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The Canterbury Earthquake Sequence adversely impacted built, economic and social environments. This included widespread physical damage to the water supply pipe network in Christchurch, resulting in long service disruptions. ...
Investigation of vertical reinforcement termination in lightly reinforced concrete walls
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Reinforced concrete (RC) structural walls are effective lateral force-resisting components commonly implemented in tall buildings. Recent studies have investigated the impact of minimum vertical reinforcement limits on the ...
Adequacy and Retro-Fitting of Timber Frame House Foundations on Slopes
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Previous studies have indicated that there are significant issues with the structural strength and stability of many existing house foundations on sloping sites. This was confirmed after the Christchurch earthquakes, where ...
Hazard-consistent collapse risk assessment of steel moment frame buildings in Wellington
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study evaluates the seismic collapse risk of two modern ductile steel moment frame buildings designed as per the NZS 1170.5 seismic design standard. A four and twelve storey steel moment frame buildings located in ...
Wellington basin amplification: research goals and update from the National Seismic Hazard Model Programme
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In Wellington, 3D basin amplification effects observed at 1 – 2 second spectral periods were identified as one factor likely to have exacerbated damage to mid-rise structures during the 2016 Mw 7.8 Kaikōura earthquake ...
