Source modelling considerations for ground motion simulation validation of moderate magnitude active shallow crustal earthquakes in New Zealand
(2020-04-22)This paper summarises progress toward NZ-wide physics-based hybrid broadband ground motion simulation validation of moderate magnitude (5.0 < Mw < 7.0), active shallow crustal earthquake events through low spatial resolution ... -
A statistical approach to determine the seismic design parameters in the asymmetric sliding hinge joint using Belleville Springs
(2020-04-22)The design philosophy has changed over the past 20 years in seismic engineering. Structures moved from failing in a controlled ductile manner, to low damage design, to more recently, nearly no damage design (S. Ramhormozian, ... -
Seismic assessment and restraint of non-structural element - practical solutions and implementation challenges
(2020-04-22)Almost 10 years have passed since the 2010 - 2011 Canterbury Earthquake Sequence (CES). These major events, and more recently the 2016 Kaikoura Earthquake have confirmed the poor performance of non-structural elements ... -
Unbonded post-tensioning of face loaded URM cavity walls under semi-cyclic and dynamic loading
(2020-04-22)An unbonded post-tensioning (PT) system installed into full-scale face loaded (out-of-plane) URM cavity walls using threaded rod and steel anchor plates spanning the cavity was investigated through experimental testing. ... -
Estimating deformation demands on steel EBF systems
(2020-04-22)The deformation capacity of a steel eccentrically braced frame (EBF) structure is typically governed by the chord rotation capacity of the EBF links. Codes allow these chord rotation demands to be estimated a variety of ... -
Cybershake NZ v19.5: New Zealand simulation-based probabilistic seismic hazard analysis
(2020-04-22)This paper presents a concise summary of the computational workflow and results of the May 2019 version (v19.5) of probabilistic seismic hazard analysis (PSHA) in New Zealand based on physics-based ground motion simulations ... -
Seismic retrofitting of RC-frames using Resilient Slip Friction Joint toggle-bracing system
(2020-04-22)Seismic retrofitting of the current non-ductile or limited ductile RC buildings is one of the challenging design topics among the scholars and engineers. The common technique for RC-frame retrofitting involves adding ... -
Full-scale shaking table testing of a low-damage steel structure using Resilient Slip Friction Joint
(2020-04-22)The objective of this study is to give an overview of the design and numerical analyses related to a full-scale steel structure shaking table test that includes some structural applications of Resilient Slip Friction Joint ... -
Geotechnical outputs from the EQC – Quake Centre Industry Fellowship programme
(2020-04-22)The Earthquake Commission (EQC) has, for a long time, been an important investor in high quality research in New Zealand. EQC’s research programme spans science, engineering and social science and has played a vital role ... -
Predicting yielding of gusset plates in seismic frames using finite element modelling
(2020-04-22)Gusset plates connect lateral bracing to a building by fixing two perpendicular edges into the corners of a frame. This results in a gusset plate having a non-uniform cross-sectional area and generally, each gusset plate ... -
Real world investigation of seismic performance of buildings with hollowcore floors
(2020-04-22)The cyclic test on a super-assembly of hollowcore floor and frames at the University of Canterbury around 2003 revealed the seismic vulnerability of hollowcore floor practice at that time. Subsequent tests were conducted ... -
Annexes G and H of the Dutch Seismic Practice Directive NPR9998
(2020-04-22)The province of Groningen in the north-east of the Netherlands is currently experiencing a period of induced seismicity as the result of sustained gas extraction from an underlying gas field. These anthropogenic earthquakes ... -
Prioritization of seismic retrofit using scoring system
(2020-04-22)As the research and engineering communities advance in their understanding of earthquakes and the associated effects, it becomes apparent that retrofit of old structures is necessary in order to protect the lives and assets ... -
Element exchange search algorithm for optimal placement of viscous dampers for building structures
(2020-04-22)Optimal design of supplemental dampers efficiently enhances the seismic performance of structures. Existing methods of optimal damper placement design either require a large amount of iteration or can only reliably arrive ... -
Earthquake Science at University of Otago
(2020-04-22)Since the establishment of University of Otago’s Earthquake Science Chair in early 2016, our activities have been multidisciplinary, comprising: paleoseismology; earthquake statistics; ground motion simulations; seismic ... -
Wāhine tapuhi ō te parawhenua mea kia mataara- Wāhine-led, community-based research on earthquake resilience
(2020-04-22)Despite increasing attention on the importance of earthquake risk reduction for Aotearoa New Zealand communities, there are limited Māori-medium resources available, and more representation of Māori wāhine (women) researchers ... -
An automated wireless-based system for real-time health monitoring of civil infrastructures
(2020-04-22)This paper presents a structural health monitoring (SHM) system based on wireless smart sensor network for real-time condition assessment of civil infrastructures. The system consists of a new wireless smart sensor network ... -
Earthquake prone building policy implementation in Lower Hutt
(2020-04-22)Lower Hutt building stock dates back to early nineteenth century, with the majority of older buildings concentrated in central business district and around historic precincts in Jackson Street. Inevitably, buildings built ... -
Earthquake-resilience of storage tanks: using an innovative anchorage system
(2020-04-22)In this study, a new anchorage system has been introduced by employing the recently developed Resilient Slip Friction Dampers (RSFDs) as ductile self-centring hold-downs for liquid storage tanks. This new anchorage mechanism ... -
