A Case for Resilience in New Zealand
(2024-04-09)The concepts of resilience and holistic building performance drive the seismic design approach for structures with national significance or special post-disaster functions. Although considerable advancements have been made ... -
A Review on Nonlinear Time History Analysis of Structures
(2024-04-09)Nonlinear time history analysis (NTHA) is a powerful approach for assessing the seismic response of buildings, enabling engineers to better understand and predict the structural behavior under dynamic loading. This review ... -
A risk-based framework to account for step-change behaviour in seismic assessment
(2024-04-09)In New Zealand, the seismic assessment of existing buildings focuses on life safety risk. The assessed capacity of a building is limited by the capacity corresponding to any vulnerability (or weakness) that can potentially ... -
An energy dissipation and seismic reduction design of a hospital inpatient building using viscous fluid dampers
(2024-04-09)Viscous fluid damper is commonly used in China to reduce building seismic response. This paper introduces the design methodology and key-points of viscous fluid damper in China using an energy dissipation design of an ... -
Analysis of Felt Detailed ‘Final Comments’ for the 2016 Kaikōura earthquake
(2024-04-09)The GeoNet “Felt Detailed” survey collects information about people’s experiences after earthquakes - from behavioural responses through to damage to buildings and infrastructure. One of the questions asked at the end of ... -
Analysis of Site-Response Residuals from Empirical Ground-Motion Models to Account for Observed Sedimentary Basin Effects in Wellington, New Zealand
(2024-04-09)Analysis of prediction-observation residuals from the empirical ground motion models (GMMs) used in the 2022 New Zealand National Seismic Hazard Model (NZ NSHM) update indicates a general underprediction of ground motions ... -
Applicability of existing CPT-Vs correlations to direct-push crosshole and cone penetration test data for shallow Holocene-aged New Zealand soil deposits
(2024-04-09)A number of empirical correlations have been proposed to estimate shear wave velocity (Vs) using cone penetration test (CPT) data as a result of the growing availability of global databases. The performance of four existing ... -
Application of Low Damage Tension Braces in Top Extensions of Existing Buildings: A Case Study for Seismic Upgrade
(2024-04-09)Tension-only braces are generally used as diagonal cross members (rods, flat bars or similar) to resist lateral loads. The application of these braces has been limited to low-rise buildings (generally up to two stories) ... -
Assessing the Impact of Drilling Techniques on the Tensile Strength of Mechanical Screw Anchors in Masonry
(2024-04-09)Mechanical screw anchors are used for a range of structural connections on masonry buildings, including as part of earthquake retrofit solutions. While extensive research has been devoted to understanding the working ... -
Bridging engineering and social perspectives of post-earthquake functional recovery of commercial buildings
(2024-04-09)The emerging post-earthquake functional recovery concept is gaining momentum among building professionals and policymakers. It highlights the importance of incorporating recovery-oriented objectives into building codes, ... -
Building collapse due to P-delta – what is the risk?
(2024-04-09)Second-order P-delta effects require consideration as part of the seismic design and assessment of buildings, as they can amplify lateral displacement demands and potentially cause collapse through dynamic instability. ... -
Challenges associated with geotechnical design of Te Kaha – Canterbury’s Multi-Use Arena
(2024-04-09)Te Kaha is a new 36,000-seat permanently covered multi-use arena in Christchurch and is the final anchor project in the Christchurch Central Recovery Plan, following the Canterbury earthquake sequence of 2010-2011. The ... -
Code Based Design vs. Performance Based Design
(2024-04-09)Modern day design codes are the result of six decades of seismic engineering developments most of which have been focused on elastic modal methods. Modal methods are strictly not applicable to inelastic systems and hence ... -
Communicating seismic risk with commercial building tenants: Preliminary results
(2024-04-09)In Aotearoa New Zealand, the interpretation of seismic risk information and the subsequent demands put on building owners and developers, are shaping the performance of our building stock. Commercial building tenants, in ... -
Comparing alternative methods to account for shallow site effects in hybrid broadband ground-motion simulations
(2024-04-09)Shallow site effects are usually not explicitly modelled in hybrid broadband ground-motion simulations, and their proper incorporation may be key to improving prediction at soil sites. This paper examines five methods to ... -
Comparison between weld sizing methods included in steel structure standards
(2024-04-09)Although the weld sizing methods given in standards look simple, the actual stress distribution in most welds is complex. Some simplifications are assumed to make designing welds easier for design engineers in different ... -
