Modelling of residential house perimeter foundation beams subjected to ground deformations
(2023-04-19)The 2010-11 Canterbury earthquake sequence is the most damaging and disruptive seismic event to affect New Zealand, resulting in repair costs totalling approximately NZ$40 billion. Liquefaction induced ground deformations ... -
Multidirectional cyclic testing of self-centering cross-laminated timber shear wall sub-assemblies
(2023-04-19)Driven by demand for sustainable buildings, mass timber, specifically cross-laminated timber (CLT), is being more widely used in mid-rise buildings in the US. In areas of the US with a significant seismic (i.e., earthquake) ... -
Multistage Friction Connections
(2023-04-19)Multistage friction connections (MFCs) are bolted connections for dissipating seismic energy while reducing peak displacements and encouraging recentring. MFCs comprise two symmetric friction connections co-linearly ... -
Numerical Investigation of Australasian Cold-Formed Steel strap-braced walls under lateral and vertical load
(2023-04-19)Cold-Formed Steel (CFS) gained popularity in residential buildings due to its dimensional accuracy, lightweight, resistance to shrinking and creeping, durability, low embodied carbon and CNC manufacturing abilities. The ... -
Numerical parametric analysis of gravity column base-plate connections
(2023-04-19)Gravity column base-plate connections are normally treated as pinned connections in design. Correspondingly, a low rotational stiffness value is specified in the New Zealand steel design standard, NZS 3404. However, previous ... -
Optimisation through an Alternative Solution approach to incorporating soil-structure interaction
(2023-04-19)The New Zealand Building Code is performance based. However, the most commonly adopted design methods utilise capacity-based Verification Methods such as B1/VM1. Although considerable time and cost is typically associated ... -
Optimising seismic resilience assessments -Part II:Integrating geophysical and geotechnical investigations
(2023-04-19)In a country frequently shaken by earthquakes, understanding the risk to infrastructure from seismic shaking is a vital part of any construction project. With no single technique able to fully capture the seismic hazard ... -
Optimum service and seismic structural protection with adaptive dampers and base isolators for immediate occupancy after the earthquake
(2023-04-19)To improve serviceability of important civil structures during seismic action, base isolators and dampers need to perform with high efficiency independent of the ground shaking level. In service and seismic actions, base ... -
Performance assessment of shallow founded buildings on liquefiable soils
(2023-04-19)In evaluating foundation options for sites featuring liquefiable soils, shallow raft foundations may remain a suitable and preferred solution, provided the seismic performance can be demonstrated to be adequate. In evaluating ... -
Performing Structural Assessment using Acoustic Measurements
(2023-04-19)Natural hazards, such as earthquakes, could be catastrophic. One challenge that society faces is how to provide a rapid and accurate evaluation of the structural damages after the events. Traditional visual inspection is ... -
Post-disaster building functionality: preliminary findings of a systematic review
(2023-04-19)During a natural hazard event, buildings are likely to experience some sort of damage, thus limiting their ability to function as intended. The severity of the ensuing consequences for various stakeholders and the community ... -
Predictive models for changes in reinforcement characteristics due to strain ageing effects
(2023-04-19)One of the factors affecting repair feasibility of buildings damaged by earthquakes is the potential effects of strain ageing of reinforcement. Since strain ageing can lead to an increase in structural member strength and ... -
Public expectations of damage and disruption to existing multi-storey buildings in earthquakes
(2023-04-19)The seismic performance of both structural and non-structural building components have the potential to affect the lives of building occupants, with poor performance likely to cause undue disruptions to the lives of building ... -
Reimagining Community Resilience through a Te Ao Maori Worldview
(2023-04-19)Efforts to improve community resilience have seen universal efforts to grow capabilities in disaster management for the built environment. Although comprehensive frameworks exist, the perspective used to derive these ... -
Response of Retrofitted 3D RC Frames under Dynamic Loading Conditions
(2023-04-19)In this study, the response of 3D double story reinforced concrete (RC) frames retrofitted through a diagonal friction damper under dynamic loading conditions, was evaluated using shaking table tests. A friction damper ... -
Retrofit and Repair of Reinforced Concrete Columns with Active Confinement
(2023-04-19)There are too many reinforced concrete (RC) columns built before the 1970s without sufficient transverse reinforcement. Past earthquakes have demonstrated the vulnerability of such columns and the need for their retrofit. ... -
Review and suggestions on timber buildings with hybrid lateral force resisting systems
(2023-04-19)Timber-framed structures have long been the default structural form for residential construction in many countries, including New Zealand. However, for some complex low-rise and mid-rise buildings, hybrid Lateral Force ... -
Risk thresholds in the built environment
(2023-04-19)Engineering and building design inherently deal with risk. But risk is rarely—if ever—explicitly considered. Most building design in Aotearoa New Zealand (i.e., to B1/VM1 NZS1170) targets an annual individual fatality risk ... -
Seismic application of fillet and partial penetration butt welds
(2023-04-19)Fillet and partial (incomplete) penetration butt welds are the most cost-effective weld details for structural steel connections. Correctly sized and executed, double-sided, balanced fillet welds and partial penetration ... -
Seismic Behaviour of Slender Rectangular Reinforced Concrete Walls based on analytical methods
(2023-04-19)In the seismic design and assessment of structures, one of the key parameters is the displacement capacity of the structural elements. Slender reinforced concrete (RC) structural walls are one of the more commonly used ...
