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 ...
Advancing NZ Hospital seismic readiness: creating a post-earthquake functionality dashboard
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Continued functionality of critical infrastructure systems, such as hospitals, shortly after an earthquake is expected. However, experience indicates that there may be some disruption due to damage, outages, or access that ...
Shake Table Tests of a Six-Span Steel Bridge Model for Nonlinerality Identification
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Most of real structures exhibit nonlinear behaviour during their lifetime. Nonlinear behaviour of a structure can be as a result of a local effect (friction in joints, joint and link flexibility, and nonlinear contact) or ...
A case study of Soil-Foundation-Structure-Interaction for aseismic design of wind turbines
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Wind farms in New Zealand have a combined capacity of about 690 MW and supply around 6% of New Zealand’s annual electricity generation. This is about the amount of electricity 300,000 kiwi homes use in a year. Wind farms ...
Ductile timber connections: Understanding the factors contributing to their ductility
(New Zealand Society for Earthquake Engineering, 2022-04-27)
It is well accepted that ductility in a timber structure is achieved through its conections as the behaviour of timber is inherently brittle. It is thus important to understand the diferent parameters that contribute to ...
Seismic structural monitoring in Wellington using advanced seismological techniques
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Sklodowska et al. (2021) employed advanced seismological techniques usually applied to Earth studies to the Te Puni building (instrumented as part of the GeoNet building instrumentation programme) for the 2009-2017 ...
