Method for the explicit consideration of ground motion duration in NZS 1170.5
(2023-04-19)Recent studies have demonstrated that longer earthquake ground motion duration can reduce structural deformation capacity and increase collapse risk. This study introduces a method to explicitly account for such effects ... -
Behaviour of Unreinforced R.C. Beam-Column Joints Under Bidirectional Loading
(2023-04-19)Modern building codes for reinforced concrete (RC) frame structures in areas susceptible to earthquakes prescribe detailing requirements for the beam-column joint to prevent shear failure and subsequent loss of gravity ... -
Trends in systematic site residuals with geomorphic categories for New Zealand ground-motion instrument sites
(2023-04-19)This study investigates systematic site-effects from prediction residuals of physics-based ground-motion simulations for a database of small magnitude (i.e., 3.5 ≤ MW ≤ 5) shallow crustal earthquakes in New Zealand. The ... -
Dynamic analysis of tall reinforced concrete walls designed with minimum vertical reinforcement
(2023-04-19)Analysis of tall walls subjected to the earthquake ground motions highlights the amplified dynamic moment response at the mid-height due to the higher mode effect. The amplified moment demand may result in unexpected ... -
Estimates of site periods from mHVSR analysis of IRIS temporary seismograph networks
(2023-04-19)The effects of soil stratigraphy and sedimentary basins on earthquake ground shaking are well-established. These effects can be represented using a range of site metrics, with the focus of this paper being the fundamental ... -
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 ... -
Testing of heavily damaged reinforced concrete walls repaired using concrete and steel replacement
(2023-04-19)Post-earthquake damage assessments are essential to decisions on the need for and extent of structural repairs. Despite this, New Zealand currently has no official guidelines to evaluate the residual capacity of ... -
Experimental study on structural performance and damage characteristics of repaired flexural RC members
(2023-04-19)Understanding the expected seismic performance recovery of repaired members is important to make an effective recovery plan for damaged buildings. In this research, three RC beam and three RC wall specimens were subjected ... -
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 ... -
Seismic Performance Comparison of New Zealand and Japanese Concrete Moment Frames
(2023-04-19)Observations of the performance of reinforced concrete (RC) buildings after the 2016 Kumamoto earthquake in Japan showed buildings designed using Japanese standards resulted in less damage and downtime compared to buildings ... -
Wellington Children’s Hospital - a different approach to a seismic restraint project
(2023-04-19)The seismic restraint design for non-structural elements in the new, Importance Level 3, Wellington Childrens Hospital building utilised a considered and efficient design approach that minimise the number of seismic ... -
Lincoln University Waimarie building: An application of friction damping devices with recentring for low damage design
(2023-04-19)The experience from Christchurch and Kaikoura seismic events demonstrated well that the ‘life safety’ criteria is not sufficient to protect the community from earthquake impact. Currently, the community expects more measures ... -
Understanding and Improving the Seismic Resilience of Hospital Buildings
(2023-04-19)The establishment of Te Whatu Ora – Health New Zealand has enabled more direct national oversight of public hospital buildings across New Zealand. This has also led to the need for a more comprehensive understanding of ... -
Developing Construction 4.0 transformation of Aotearoa New Zealand's construction sector
(2023-04-19)Aotearoa’s construction industry reached over $20.5 billion in 2019 and it became the fourth largest workplace in the year ended June 2021, significantly contributing to New Zealand’s economy. However, it has long been ... -
Simplified approach to rapidly predict road blockages caused by co-seismic landslides
(2023-04-19)The 2016 Kaikōura earthquake triggered tens of thousands of landslides leading to several road blockages which isolated the population in Kaikōura and disrupted the transport services across the South Island. The prediction ... -
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 ... -
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 ... -
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 ... -
Earthquake Design Pressures from Soil Interaction on Building Basement Walls
(2023-04-19)Free-standing retaining walls are usually designed for earthquake loads using the Mononobe-Okabe method and assuming cohesionless soil backfill. The method assumes active pressure develops as a consequence of a failure ...
