A holisic methodology for assessing post-earthquake hospital functionality
(2021-04-14)Hospitals play a critical role in ensuring community safety. Hospitals must remain operational during and after an earthquake. However, physical damage, utility outages, or supply shortages can cause closures and/or ... -
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 ... -
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 ... -
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 ... -
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 ... -
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, ... -
Monotonic and Cyclic Pushover Testing of Isolated Piles of the Whirokino Trestle
(2021-04-14)In New Zealand, over 60% of State Highway bridges were designed and built during eras with low seismic provisions and most of these bridges are supported by pile foundations. An improved understanding of the in-service ... -
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 ... -
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 ... -
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 ... -
Seismic Restraint Design and Documentation for the Christchuch Acute Services Building
(2021-04-14)Seismic restraint design in New Zealand for large services intense buildings is a developing field. There are few examples of services intense Importance Level 4 buildings where fully compliant and modelled seismic restraint ... -
Seismic Strengthening Auckland's Waterfront
(2021-04-14)Seawalls were constructed in sections between 1879 and 1925 to form Quay Street on the waterfront of Downtown Auckland. These seawalls have essentially remained structurally unchanged since they were first constructed and ... -
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 ... -
Using a self-centring friction damper as anchorage system for industrial tanks and vessels
(2021-04-14)The conventional tank’s connections make the tanks to be either fully restrained or free for rocking motion, which generally creates a high level of force due to lack of ductility or large displacement demand due to uplift ...
