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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...
