Enhancing seismic performance of existing buildings using viscous dampers for Forward-Directivity Earthquakes – The Challenges
(2021-04-14)Enhancing the performance of an existing building with viscous dampers for a Wellington site requires thorough consideration of near-fault effects, the Wellington Fault being so close. Earthquake records with forward-directivity ... -
Enhancing seismic performance of structure with different configuration of passive D3 viscous damper
(2021-04-14)For each structure and project, there is a unique desire. Seismic building performance can be increased using dissipation systems like viscous dampers. However, these improvements are offset by the added cost if the total ... -
Evaluation of assessment approaches for soil-foundation-structure interaction of frame buildings
(2021-04-14)The consideration of soil and foundation deformations within the seismic assessment of buildings can be critical for evaluating the likely load paths and consequent deformations. Frame buildings provide numerous complexities ... -
Evaluation of seismic performance of buildings and infrastructure
(2021-04-14)Observations from the Canterbury and Kaikoura earthquakes are used to illustrate some important factors that often govern the seismic performance of ground, buildings and infrastructure. The talk examines some of the ... -
Experimental and analytical evaluation of different failure modes of self-centring braces
(2022-04-27)As resilience of structures during seismic events is currently a main structural engineering topic, Low-damage self-centring braces have the potential to serve this purpose by becoming a common low-damage lateral load ... -
Experimental loading protocols to evaluate the seismic performance of floor systems
(2021-04-14)Major earthquakes, such as the Canterbury and Kaikoura events recorded in New Zealand in 2010 and 2016 respectively, highlighted that floor systems can be heavily damaged. At a reduced or full scale, quasi-static experimental ... -
Experimental seismic characterisation of gravel-granulated tyre mixtures and design implications
(2021-04-14)Worldwide, due to the large amount of end-of-life tyre (ELT) stockpiles, reusing and recycling of ELTs in civil engineering applications have become a priority, significantly contributing to lessen environmental and health ... -
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 ... -
Geotechnical challenges and design solutions for Yarrow Stadium redevelopment
(2022-04-27)New Plymouth Yarrow Stadium’s two grandstands were declared earthquake-prone and closed in 2017-2018. The $50m repair and refurbishment project was approved in 2019 and subsequently reviewed and modified to allow for the ... -
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 ... -
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 ... -
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) ... -
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 ... -
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 ... -
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 ... -
Numerical modelling of a concrete wall-steel frame building
(2021-04-14)Buildings that use concrete walls together with steel frames have become increasingly common in Christchurch, with around 35% of post-earthquake buildings using such mixed-material structural systems. This rapid shift in ...
