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 ... -
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 ... -
Review of recently constructed buildings that combine steel frames and concrete walls
(2020-04-22)Recent building construction in New Zealand has exhibited an increase in the use of structural steel due to its availability and perception of good seismic performance. Despite the renewed popularity of structural steel ... -
Robustness and accuracy of model-free structural health monitoring
(2020-04-22)Rapid, accurate structural health monitoring (SHM) assesses damage to optimise decision-making. Many SHM methods are designed to track nonlinear stiffness changes as damage. However, highly nonlinear pinched hysteretic ... -
Scion Hub: A three storey seismically resilient timber diagrid
(2020-04-22)The new three storey Hub building at Scion’s campus in Rotorua is an innovative approach to providing seismic resilience in timber. A demonstration project for Scion’s work in the timber industry it utilises several forms ... -
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 ... -
Seismic base isolation of high-rise RC shear wall building using lead core rubber bearings
