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, ... -
Towards a better understanding of the development of the strength in Asymmetrical Friction Connections (AFCs)
(2020-04-22)In the current design practice, the strength of Asymmetric Friction Connections (AFCs) is calculated considering the friction force developed at both sliding interfaces using the bolt tension reduced by the moment – shear ... -
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 ... -
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 ... -
Structural engineering observations from the 26 November 2019 M6.4 Albanian earthquake
(2020-04-22)The Mw 6.4 earthquake that occurred near the city of Durres, located on the west coast of Albania, may be considered small in comparison to the design earthquake, yet it caused an enormous amount of damage to buildings. ... -
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 ... -
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 ... -
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 ... -
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 ... -
The New Zealand Building Code - a rethink?
(2020-04-22)Are the regulatory settings for structural and geotechnical design of structures in New Zealand currently appropriate? It is contended that they are not. New Zealand led the world in performance based building regulation ... -
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 ... -
The Scott Base Redevelopment: design response to natural hazards
(2020-04-22)The Antarctic environment is extreme, making consideration of resilience crucial for survival. This paper outlines how site-specific hazards are being considered within a resilient design framework for the Scott Base ... -
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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
A simple method to predict floor response spectral demands on nonstructural components
