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 ... -
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 ... -
Seaview Wharf: risk-based thinking underpins the future
(2021-04-14)Wellington’s Seaview Wharf is a critical asset in the Lower North Island fuel supply system, including after significant seismic events. Recent annual fuel supply for the region has exceeded 1 Million tonnes, and there is ... -
CentrePort Wellington: Resilient regeneration activity
(2021-04-14)Wellington’s Pipitea port precinct - a critical lifeline and economic contributor to Wellington and surrounding regions – suffered significant damage and associated operational disruption as a result of the 2016 Kaikoura ... -
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 ... -
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 ... -
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 ... -
Development of Dissipative Controlled Rocking Bridge Columns on Monopile Foundations
(2021-04-14)In this research, a low-damage seismic design detail is developed for bridge columns supported on monopile foundations. The low-damage system aims to minimise, and potentially eliminate, the repair time and costs to a ... -
Wellington Building Inventory: Rapid Earthquake Response Framework
(2021-04-14)This paper is focused on the design and implementation of a functional tool to evaluate and communicate the seismic risk to increase resilience and reduce human and economic loss. Wellington has been selected as the case ... -
The Assessment of Liquefaction induced Settlement - application within Engineering Practice
(2021-04-14)The assessment of the magnitude of liquefaction-induced settlements affecting shallow founded buildings and buried services is an important yet challenging task for geotechnical engineers. It is often required when assessing ... -
Case studies on low damage mass timber structures with resilient connections
(2021-04-14)There is increasing public pressure to have seismic-resistant structures made with massive wooden panels such as Cross Laminated Timber (CLT). It is well-known that the type and behaviour of the connections govern the ... -
Philosophical reflexions following the Lyttleton 2011 New Zealand Earthquake: Ten years after
(2021-04-14)At 12:51 p. m. on 22 February 2011, the Mw 6.3 Lyttelton earthquake struck the Canterbury region of New Zealand. The seismic event was reported as the result of the rupture of a previously unknown geological fault, 5.9 km ... -
Base isolation: the good, the bad and the ugly
(2021-04-14)In the light of the recent Christchurch and Kaikoura earthquakes and the life safety and economic uncertainties they pose, the need for “low damage design” has become more important. In theory a “low damage design” should ... -
Cyclic behaviour of hold-downs using mixed angle self-tapping screws in Douglas-fir CLT
(2021-04-14)Long self-tapping screws are now commonly used in mass timber construction in New Zealand and globally due to their high strength and ease of installation on site. Under axial loads, self-tapping screws are strong and stiff ... -
Rebuilding Christchurch following the Canterbury earthquakes – implementation of geotechnical lessons learnt
(2021-04-14)Liquefaction during the Canterbury Earthquakes caused significant damage to the built environment of Christchurch and posed a significant challenge to the rebuild effort. This paper describes the process the geotechnical ... -
A comparison of New Zealand seismic code requirements with other major design codes in the implementation of seismic resilient devices
(2021-04-14)In the ever-evolving earthquake engineering field, the need of the hour is to achieve earthquake-resistant buildings which have immediate occupancy following an earthquake. This implies that the demand for resilient dampers ... -
Shake table testing of fire sprinkler piping systems typical of New Zealand practices
(2021-04-14)An automatic fire sprinkler piping system requires an intricate piping network to feed individual sprinklers spread across the plenum space. In practice, this elaborate piping network is braced against seismic demands ... -
The top enablers and barriers of seismic technology adoption in construction
(2021-04-14)The slow process of adoption of the new technologies has been identified as a significant issue in the construction industry. In order to address this issue, the top enablers and barriers of the adoption process are needed ... -
