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 ... -
Seismic Damage States and Damage Quantification of Light Timber Framed Walls in Residential Houses
(2023-04-19)New Zealand (NZ) has a performance-based code environment. The essence of performance-based seismic design of buildings is to achieve multiple performance requirements including damage control. However, the current seismic ... -
Seismic design for temporary works: Recommendations for a Temporary Works forum NZ design note
(2023-04-19)The Temporary Works forum NZ (TWf NZ) aims to improve construction safety by addressing risk in the design and execution of temporary works. Anecdotal evidence suggests that seismic actions on temporary works are often ... -
Seismic design of an XblocPlus® revetment using multi-model approach
(2023-04-19)When designing and constructing revetments, there is often a drive to reduce the footprint due to space constraints and a limited supply of suitable rock armour materials. Concrete armour units present a potentially more ... -
Seismic design of suspended lightweight ceilings – what’s the ductility?
(2023-04-19)In the last few years, the design of suspended ceilings has gone through significant change and the level of compliance required has increased substantially. This was largely due to the generally poor performance of these ... -
Seismic hazard analysis for a bridge across Marikina River with consideration of near-fault effects
(2023-04-19)The Valley Fault System in Metro Manila, Philippines is widely considered to be an impending threat in releasing a large-scale earthquake. Such earthquake is forecasted to impose severe casualties and economic losses to ...
