Concept design of a steel frames post-disaster shelter utilising containers
(2020-04-22)Nowadays, numerous earthquakes happen every year with many resulting in large potential aftershocks. Tents and portable dwellings are widely used as emergency shelters. However, tents can only be used for days or weeks, ... -
Correlation between standard penetration test and shear-wave velocity in Wellington, New Zealand
(2020-04-22)The New Zealand standard NZS1170.5:2004 (amendment 1; Sep 2016; Earthquake actions) recommends seven methods for the determination of site classification as defined in Section 3.1.3.1. The most preferable method is direct ... -
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 ... -
Cyclic tests of an innovative seismic bracing member - multiple U-shaped flexural plates dissipater
(2020-04-22)Following Canterbury earthquake sequence, there has been an increasing interest in development of low-damage structural design using supplemental damping such as the use of metallic dissipaters. In this research, an ... -
Design scenarios for piles in ground subject to liquefaction
(2020-04-22)Seismic shaking and liquefaction with its associated loss of soil strength and ground movements/deformations can be damaging to buildings and their foundations. Understanding ground behaviours and soil-structure interaction ... -
Developing guidelines for the seismic assessment of glazing systems
(2020-04-22)There is an increasing recognition that the seismic performance of buildings will be affected by the behaviour of both structural and non-structural elements. In light of this, work has been progressing at the University ... -
Developing hysteresis curves for the optimised sliding hinge joint with asymmetric friction connections
(2020-04-22)The semi-rigid Sliding Hinge Joint (SHJ) beam-column connection for steel moment resisting frames is a successful low damage system that shows a lot of promise in earthquake engineering. It allows for relative beam-column ... -
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 ... -
