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 ... -
Investigating the impact of design criteria on the expected seismic losses of an office building
(2021-04-14)Low Damage Seismic Design (LDSD) guidance material being developed by Engineering NZ is considering a design drift limit for multi-storey buildings of 0.5% at a new damage control limit state (DCLS). The impact of this new ... -
Investigation of the Plastic Drift Capacity of RC Frames with Beam-Column Joint Failure
(2021-04-14)MBIE/NZSEE guidelines have various methods to assess existing buildings, of which Displacement Based Assessment (DBA) is one. This paper reports on the application of DBA to reinforced concrete (RC) frames where beam-column ... -
Investigation of vertical reinforcement termination in lightly reinforced concrete walls
(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 ... -
Is the bar too high? Foundation settlement in post-earthquake Christchurch
(2021-04-14)Three case studies are presented to show how significant ground deformation occurred with the Canterbury earthquake sequence, which in turn resulted in slopes to shallow foundations. The case studies are all from the ... -
Liquefaction Assessment of Reclaimed Land at CentrePort
(2021-04-14)The 2016 Mw7.8 Kaikōura earthquake caused widespread liquefaction in the port of Wellington (CentrePort), New Zealand which produced substantial lateral ground movements along with global and differential settlement. ... -
Liquefaction Risk Analysis of Native and Reclaimed Soil Deposits in Central Wellington
(2021-04-14)Following the 2016 Kaikōura earthquake, severe and damaging liquefaction was observed at the port of Wellington in areas of reclamation fills built at the beginning of or mid 20th century. However, little or no damage was ... -
Low damage solution for a biomass boiler structure by a new three-dimensional seismic isolation
(2021-04-14)The February 2011 Christchurch earthquake caused significant property damage within Christchurch city. Since this devastating event, there has been a shift in engineering practice to Performance Based Design (PBD), to limit ... -
Managing Seismic Risk across Process and Manufacturing Facilities
(2021-04-14)To manage seismic risk at large Process and Manufacturing Facilities requires a PCBU to understand the compliance requirements from legislation. However this is not an easy task as there are multiple Acts, Regulations, ... -
Monitoring of lateral stiffness changes for a real building using hysteresis loop analysis
(2021-04-14)The BNZ building in Wellington, New Zealand was significantly damaged, and eventually demolished, due to the cumulative impact of three main earthquakes between 2013 and 2016. Although the building was equipped with a set ... -
