Liquefaction-Induced Parabolic Subsidence Method for analysis of shallow foundations
(2024-04-09)In New Zealand, the document “Repairing and Rebuilding Houses Affected by the Canterbury Earthquakes" issued by the MBIE, has been widely embraced by consulting engineers and local authorities as a reference for building ... -
Low-Rise Buildings Guideline – Stage 1 Review
(2024-04-09)The seismic assessment of low-rise buildings is an important area of seismic assessment in New Zealand given the prevalence of these types of structures, especially outside the main centres. The Joint Committee for the ... -
Machine Learning Correction of Overpredicted Liquefaction Manifestation using Liquefaction Severity Number
(2024-04-09)Many of state-of-practice methods for predicting liquefaction manifestation, such as the Liquefaction Severity Number (LSN) of van Ballegooy et al. (2014) are known to suffer from significant overprediction in regions ... -
Moment Curvature Analysis of wide-flange steel columns with local buckling dominant mode of failure
(2024-04-09)One of the key information that can provide an insight into the seismic behaviour of structural elements is their force-displacement curve. Such a curve can be obtained based on a moment-curvature analysis and using an ... -
Multi-scenario approach for the assessment of liquefaction exposure and impact across New Zealand State Highways
(2024-04-09)Events such as the 2010-2011 Canterbury Earthquake Sequence or the 2016 Kaikōura earthquake demonstrated the impacts of liquefaction and lateral spreading across New Zealand infrastructure networks. Statistical liquefaction ... -
Multistage Friction Connection Optimisation
(2024-04-09)This paper describes the use of multi-stage friction connections (MFCs) to modify hysteresis curve characteristics of structures in order to decrease their peak and residual displacements. Both cases with and without P-delta ... -
Nationwide investigation of systematic site effects in New Zealand: Residual analysis of physics-based ground motion simulations
(2024-04-09)This study examines systematic site effects from the prediction residuals of physics-based ground motion simulations using a dataset of small magnitude (3.5 ≤ Mw ≤ 5.0) active shallow crustal earthquakes recorded in New ... -
New Zealand National Seismic Hazard Model Revision 2022: Hazard changes with respect to NZ NSHM 2010
(2024-04-09)Revision of New Zealand National Seismic Hazard Model (NZ NSHM 2022) represents a significant change not only in hazard results but also in terms of methods and processes in comparison to NZ NSHM 2010. The changes span ... -
Non-contact Structural Damage Detection by Natural Frequency Measurement using Microphone
(2024-04-09)Structural Damage Detection methods are crucial for infrastructure maintenance. The general principle involves the identification of changes in natural frequencies induced by stiffness reductions. This paper introduces an ... -
NZ Industry Nonlinear Response History Guidelines
(2024-04-09)Nonlinear response history analysis (NLRHA) provisions in NZS 1170.5 were developed 20 years ago. Significant developments in the selection and scaling of ground motion records have occurred since this standard was ... -
Omāroro Reservoir: A Case Study. It’s Cheaper to Work with Nature
(2024-04-09)By all accounts, Wellington, New Zealand is a challenging seismic environment for the design and construction of infrastructure. In recent years, this challenge has increased with our deeper understanding of Aotearoa’s ... -
Out-of-plane capacity of low-damage partition wall systems: the balance between maintaining robustness and allowing relative movement
(2024-04-09)The need for low-damage non-structural systems has been apparent following many major earthquakes, where significant damage has commonly been observed to the non-structural contents of buildings. Damage to non-structural ... -
P-delta or P-theta analysis?
(2024-04-09)Engineers have methods to estimating the displacements of inelastically responding structures in earthquakes. Rules to estimate such displacements for a structure with a certain period, damping, and hysteretic behaviour ... -
Panel Zone Strength in Moment Frames with Slabs
(2024-04-09)Despite the common occurrence of composite slabs in steel structures, they are often excluded from design considerations, which may lead to undesirable panel zone yielding due to increased demands. Through the utilisation ... -
Performance of RC buildings in the 2023 Turkey-Syria earthquakes
(2024-04-09)The 2023 Mw 7.7-7.8 Turkey-Syria earthquakes were devastating events that resulted in widespread damage throughout several regions of western Turkey. In March 2023, the Architectural Institute of Japan deployed a team of ... -
Performance of Seismically Isolated High-Speed Railway Bridges against Near-Fault Ground Motions
(2024-04-09)The first high-speed rail (HSR) corridor in India, built on viaducts and bridge structures, is currently under construction between Mumbai and Ahmedabad. This corridor passes through seismic Zone III, whereas future corridors ... -
Performance-based Assessment and Seismic Strengthening of the Christ Church Cathedral
(2024-04-09)The Christ Church Cathedral is a significant landmark for New Zealand. It was severely damaged in the 2011 Canterbury earthquakes – the Tower and Rose Window/western façade of the Cathedral suffered partial collapses while ... -
Post-Earthquake Response: Update on the Improvements to the Rapid Building Assessment Process and Building Management In Emergencies
(2024-04-09)It is vital that New Zealand has both the systems in place and trained personnel ready to respond to earthquakes and other natural disasters. Rapidly assessing the usability of affected buildings and identifying an ... -
Practical issues in time-history analysis of low-rise concrete wall buildings with subterranean levels
