Seismic upgrading of friction-damped steel frames integrated with self-centring devices
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Conventional friction-based damping devices are known for their large energy dissipation capacity and economic benefits compared to other seismic mitigation systems. These devices have been implemented in many practical ...
Is the bar too high? Foundation settlement in post-earthquake Christchurch
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Three case studies are presented to show how significant ground deformation occurred with the Canterbury earthquake sequence, which in turn resulted in slopes to shallow foundations. The case studies are all from the ...
Earthquake Stories: Experiences of Building Performance in Earthquakes to enhance future building performance
(New Zealand Society for Earthquake Engineering, 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 ...
ATC-145: Influence of prior shaking on earthquake response and repair requirements for structures and elements
(New Zealand Society for Earthquake Engineering, 2021-04-14)
ATC-145 is a FEMA funded project aimed at developing a Guide for repair of earthquake damaged buildings to achieve future resilience. Thanks in part to EQC funding, the project includes substantial New Zealand representation.

Design of RSFJ Self-centring Brace for Ultimate Limit State
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In previous studies, it was shown that the RSFJ brace assembly is prone to elastic buckling for which a new mechanism composed of two telescopic sections was introduced as a remedy to increase the elastic buckling load, ...
Improvements to state school building design including the implementation of low-damage design criteria
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The Ministry of Education (the Ministry) owns one of the largest property portfolios in New Zealand, with more than 15,000 buildings spread across nearly 2,100 state schools. Following the 2010 Canterbury earthquake sequence, ...
Experimental seismic characterisation of gravel-granulated tyre mixtures and design implications
(New Zealand Society for Earthquake Engineering, 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 ...
Directing Low-Damage Seismic Design with Building Functionality
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The upcoming New Zealand Low-Damage Seismic Design (LDSD) guidance information, currently in preparation, is widely anticipated to provide a reference point for aligning low-damage seismic performance targets. A key aspect ...
Quantifying the Embodied Carbon Cost from Demolitions Following the Canterbury Earthquakes
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The 2010/2011 Canterbury Earthquake Sequence resulted in severe financial loss, loss of life and disruption in Christchurch due to liquefaction and damage from strong shaking, which led to the widespread displacement of ...
Incorporating the influence of duration on dynamic deformation capacity in seismic assessment
(New Zealand Society for Earthquake Engineering, 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 ...
