Seismic Isolation of bridges: Case Studies
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Seismic isolation is one of the most effective means of earthquake hazard mitigation. Seismic isolation bearings are typically placed in a bridge between the substructure and superstructure and physically decouple the ...
Experimental and analytical evaluation of different failure modes of self-centring braces
(New Zealand Society for Earthquake Engineering, 2022-04-27)
As resilience of structures during seismic events is currently a main structural engineering topic, Low-damage self-centring braces have the potential to serve this purpose by becoming a common low-damage lateral load ...
Application of resilient rocking cores in low damage mass timber structures: A case study
(New Zealand Society for Earthquake Engineering, 2022-04-27)
The application of mass timber structures made with massive wooden panels such as Cross Laminated Timber (CLT) has significantly increased in the last few years owing to their many architectural and structural advantages, ...
Sustainability in enhancing the resilience of major route in Wellington
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Uncertainty in the seismicity of Wellington and climate change were key issues that influenced the design of strengthening of a key arterial route in Wellington. The abstract describes the innovations and technology adopted ...
Mechanical Anchor Supplementary Shear Reinforcing as a Retrofit Technique for Hollowcore Floors
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Hollowcore floor systems have been prevalent in New Zealand construction since the 1980s. The susceptibility of these elements to fail under seismic action has been highlighted through numerous post-earthquake observations, ...
A preliminary investigation of validity of conventional single-mode pushover analysis in multi-mode systems
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Pushover analysis is a simplified inelastic analysis approach where a structure is subjected to increasing increments of monotonic imposed force or displacements to estimate the inelastic deformations in the structural ...
Seismic response of a base-isolated building under pulse-like near-fault ground motions
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Pulse-Like Near-fault ground motions are known to challenge base-isolated buildings with their capacity to create large isolation system displacements. Such earthquake records typically contain velocity pulses with long ...
Risk-targeted framework for seismic design: Maintaining serviceability
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Changes to how seismic loads are determined for building design are imminent, as necessitated by the ongoing National Seismic Hazard Model update. The authors recently proposed a framework to produce risk-targeted hazard ...
A bespoke analytical methodology for seismic safety assessment of spillway gates: case study of Waipapa dam spillway on the Waikato River
(New Zealand Society for Earthquake Engineering, 2022-04-27)
This paper presents a seismic assessment methodology tailor-made for the Waipapa Dam Spillway gates on the Waikato River which were found to have potential dam safety issues under the 1 in 2500-year annual exceedance ...
A review of international guidance for tsunami loading on buildings
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Tsunami loading on structures creates a potentially controlling structural demand that is less understood than other design loads. Guidance for tsunami loading scenarios is sparce, and there is a great deal of variation ...
