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 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 ... -
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 ... -
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 ... -
EQRNet: New Zealand's densest urban seismic monitoring network
(2020-04-22)An ultra-dense urban earthquake monitoring and effects management system is presented. We describe our learnings from the 2016 M 7.8 Kaikōura earthquake and how these motivated us to create a globally unique system of ... -
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 ... -
Finite element method for designing HF2V device force capacity
(2020-04-22)Supplemental energy dissipation devices are increasingly used to protect structures, limiting loads transferred to structural elements and absorbing significant response energy without sacrificial structural damage. High ... -
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 ... -
How would changes to serviceability limit state design criteria impact likely repair costs?
(2020-04-22)The earthquake engineering community is currently grappling with the need to improve the post-earthquake reparability of buildings. As part of this, proposals exist to change design criteria for the serviceability limit ... -
Impacts of innovation in performance-based building code
(2020-04-22)The purpose of this study is to assess the benefits and the unintended consequences of innovation in performance-based building code with an emphasis in New Zealand building code. Also, this paper examines how innovative ... -
Implimenting the NZSEE Seismic Isolation Guidlines: a practioners view over three new designs
(2020-04-22)The draft seismic isolation guidelines provide a significant step forward in promoting a consistent NZ approach to designing and demonstrating compliance in isolated buildings. This paper provides a practitioners’ point ... -
Influence of failure mode uncertainty on the collapse capacity of RC components
(2020-04-22)Acceptance criteria for reinforced concrete components are selected based on the assumption that the failure mode of a component is deterministic. This paper makes a case suggesting that such an assumption may be untrue ... -
Influence of ground motion orientation on predicted seismic compression
(2020-04-22)Seismic compression is the accrual of contractive volumetric strain in unsaturated or partially saturated sandy soils during earthquake shaking and has caused significant distress to overlying and nearby structures. The ... -
Introducing a low damage system incorporating rocking braced frame and resilient slip friction joint as a shear key
(2020-04-22)In this paper, to achieve a self-centring damage avoidance rocking framed system, RSFJ has been employed as a shear link between braced frame and its boundary columns. Such a system could be used for a single or coupled ... -
Mitigation of liquefaction induced lateral spread using jet grout shear walls
(2020-04-22)The load transfer mechanism between ground subject to liquefaction induced lateral spreading and jet grout shear walls is complex. The shear walls comprise rows of jet grout columns, constructed in a primary-secondary ... -
Modelling of vertical control in magnetic levitation for building isolation during earthquakes
(2020-04-22)Earthquakes cause significant damage to buildings due to strong vibration of the ground. Levitating houses using magnets and electromagnets would provide a complete isolation of ground motion for protecting buildings from ... -
Numerical modelling of reinforced concrete walls with minimum vertical reinforcement contents
(2020-04-22)Reinforced concrete (RC) structural walls are effective lateral force-resisting components that are commonly implemented in tall buildings. Recent studies have investigated the impact of minimum vertical reinforcement ... -
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 ... -
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 ...
