Drift Demand Estimates for Inelastic Torsional Response of Half-scale Seven-storey RC Specimens
(2021-04-14)Existing reinforced concrete buildings with irregularities are susceptible to torsional response and resulting localised damage or collapse under seismic excitation. Primary source of torsional response can be inherent ... -
Earthquake prone public buildings: balancing life safety risks and community costs
(2021-04-14)The focus on seismic risk following the 2011 Christchurch and 2016 Kaikoura earthquakes has seen the closure of several public buildings across the country. The introduction of the Building (Earthquake-prone Buildings) ... -
Earthquake Stories: Experiences of Building Performance in Earthquakes to enhance future building performance
(2021-04-14)The performance of the built environment during earthquakes plays an important role in reducing risk and enhancing the resilience of New Zealand’s urban centres. Although engineering codes and building standards regulate ... -
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 a geospatial liquefaction model using land damage data from the 2016 Kaikoura earthquake
(2021-04-14)Earthquake induced liquefaction and lateral spreading can cause major damage to buildings and infrastructure networks. Common procedures to identify exposed areas such as cone penetration testing require extensive resources ... -
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 ... -
Evaluation of the ShakeOut earthquake drill and use of protective actions in Aotearoa New Zealand
(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 ... -
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 ... -
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
