Seismic upgrading of friction-damped steel frames integrated with self-centring devices
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Conventional friction-based damping devices are known for their large energy dissipation capacity and economic benefits compared to other seismic mitigation systems. These devices have been implemented in many practical ...
Is the bar too high? Foundation settlement in post-earthquake Christchurch
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Three case studies are presented to show how significant ground deformation occurred with the Canterbury earthquake sequence, which in turn resulted in slopes to shallow foundations. The case studies are all from the ...
Evaluation of a geospatial liquefaction model using land damage data from the 2016 Kaikoura earthquake
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Earthquake induced liquefaction and lateral spreading can cause major damage to buildings and infrastructure networks. Common procedures to identify exposed areas such as cone penetration testing require extensive resources ...
Wall-to-floor connection behavior in a low-damage concrete wall building
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Following the 2010/2011 Canterbury earthquakes, approximately 60% of multi-story buildings with reinforced concrete walls required demolition. Both practitioners and researchers have increasingly realized that low-damage ...
Identifying attributes influencing failure mechanisms in unreinforced masonry buildings using machine learning
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Unreinforced masonry buildings comprise a major part of New Zealand's built heritage and were significantly damaged during the 2010-2011 Canterbury Earthquake sequence. There were 627 URM building assessed in the surveys ...
Depth and Shape of the Basement Surface Beneath Wellington City, Based on Gravity and Seismic Constraints
(New Zealand Society for Earthquake Engineering, 2022-04-27)
A new basin-depth map for the Wellington Central Business District shows a maximum depth of 540 m near the Wellington Stadium. This is twice that previously proposed. Our new basin geometry constraints are from a residual ...
Interim Results from empirical ground motion model evaluation for the NZ National Seismic Hazard Model Update
(New Zealand Society for Earthquake Engineering, 2022-04-27)
As a part of the ongoing 2022 NZ National Seismic Hazard Model (NSHM) Update, the predictive capabilities of candidate empirical ground motion models are evaluated to ascertain models which provide good prediction for NZ ...
Dealing with uncertainty in prediction of lateral spread
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Prediction of lateral spread for seismic assessment and design includes considerable uncertainty. Two widely used prediction methods are Youd et al. (2002) and Zhang et al. (2004). Five case studies across the Wellington ...
Seismic strengthening of the Seatoun Tunnel
(New Zealand Society for Earthquake Engineering, 2022-04-27)
The Seatoun tunnel is a 147m long, vehicle and pedestrian tunnel built in 1906-1907 to provide a tram connection between the suburb of Seatoun the city of Wellington. In 2011, the Seatoun tunnel structure was assessed as ...
Post-earthquake functional recovery: A critical review
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Functional recovery not only transforms the retrofit of damaged buildings from an earthquake event but also contributes to community resilience. This paper aims to provide a state-of-the-art literature review of functional ...
