Factors affecting the balancing of Gender Representation in the Engineering Industry
(2021-04-14)Gender disparity in the engineering industry is a well-recognised problem. Engineering is a growing industry, and the lack of gender balance affects the diversity of thought available to it, as well as the potential ... -
Finite Element Analyses of Hollow Core Units Subjected to Shear and Torsion
(2021-04-14)A building boom in the 1980s allowed pre-stressed hollow-core floor construction to be widely adopted in New Zealand, even though the behaviour of these prefabricated elements within buildings was still uncertain. Inspections ... -
From mud to modules and beyond - the post-2011 Christchurch evolution of earthquake geotechnical engineering in New Zealand
(2021-04-14)The extent of land damage during the Canterbury earthquakes was a wake up call. It disproportionately impacted many aspects of the recovery, including costs, time, community cohesion and individual welfare. The earthquake ... -
Full Waveform Tomography for the upper South Island region, New Zealand
(2021-04-14)In this paper, we apply Full Waveform Tomography (FWT) based on the Adjoint-Wavefield (AW) method to iteratively invert an existing 3-D geophysical velocity model for the upper South Island region, New Zealand. Through the ... -
Future Shake-table testing of a concrete building incorporating low-damage technologies
(2021-04-14)Implementation of low-damage buildings has been rapidly increasing with a range of alternative structural components, devices, and technologies available. In order to achieve low-damage outcomes the entire building needs ... -
Ground motion simulation validation with explicit uncertainty incorporation for small magnitude earthquakes in New Zealand
(2021-04-14)This study investigates the uncertainty of simulated earthquake ground motions for small-magnitude events (Mw 3.5 – 5) in Canterbury, New Zealand. 148 events were simulated with specified uncertainties in: event magnitude, ... -
Hazard-consistent collapse risk assessment of steel moment frame buildings in Wellington
(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 ... -
How effective is a composting toilet system for protecting human health in an emergency context?
(2021-04-14)The Wellington Region is highly vulnerable to large earthquakes as it is crossed by active faults. Expected timeframes of 1 to 2 years for the re-establishment of networked wastewater management services provide urgency ... -
How practitioners can work together to achieve better seismic performance outcomes for buildings and infrastructure
(2021-04-14)A key recommendation from the Canterbury Earthquakes Royal Commission was that there should be “greater cooperation and dialogue between geotechnical and structural engineers” to help improve the seismic performance of ... -
Identifying vulnerable reinforced concrete buildings in Wellington using a simple assessment methodology
(2021-04-14)The application of a simple yet effective method to assess reinforced concrete buildings in New Zealand is discussed. It is proposed that this method be used to identify and prioritise the most vulnerable reinforced concrete ... -
Identifying attributes influencing failure mechanisms in unreinforced masonry buildings using machine learning
(2021-04-14)Unreinforced masonry buildings comprise a major part of New Zealand's built heritage and were significantly damaged during the 2010-2011 Canterbury Earthquake sequence. There were 627 URM building assessed in the surveys ... -
Impact of Canterbury earthquakes on the evolution of earthquake geotechnical engineering practice
(2021-04-14)Earthquake geotechnical engineering practice has evolved in New Zealand during the past 40 years. The 2010-2011 Canterbury earthquakes provided significant impetus to the research and practice. Early evolution commenced ... -
Improvements to state school building design including the implementation of low-damage design criteria
(2021-04-14)The Ministry of Education (the Ministry) owns one of the largest property portfolios in New Zealand, with more than 15,000 buildings spread across nearly 2,100 state schools. Following the 2010 Canterbury earthquake sequence, ... -
Improving earthquake resilience in the Taupō Volcanic Zone (TVZ) using school-based seismometers and connected education programmes
(2021-04-14)Over the past decade several “seismometers in schools” programmes have been developed in Aotearoa New Zealand by a range of organisations, for a variety of reasons and aiming to achieve a range of educational outcomes. ... -
Incorporating the influence of duration on dynamic deformation capacity in seismic assessment
(2021-04-14)The dynamic deformation capacity of a structure is the peak storey drift ratio it can safely withstand without collapsing due to dynamic instability. In a previous study, the authors developed a robust procedure to compute ... -
Influence of damping models on nonlinear seismic response of a base isolated building
(2021-04-14)This paper discusses the effect of different damping models on nonlinear seismic response of a 8 storey 2D base isolated (BI) building: (1) Rayleigh damping proportional to the mass and initial stiffness matrices, (2) ... -
Innovative seismic upgrade of Left Bank Art Gallery, Greymouth.
(2021-04-14)The Grey District Council commissioned the strengthening of the C1910 Left Bank Art Galley building in 2018 to preserve its historical value and improve the building’s seismic safety rating. Formally the Bank of New Zealand ... -
Investigating CLT Lateral Load Resisting Systems for Taller Timber Buildings
(2021-04-14)Recent taller timber buildings worldwide have often utilized hybrid systems of mixed materials and have been built in regions of low seismicity. Designers often adopt the hybrid material solution of utilizing mass timber ... -
