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 ... -
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 ... -
Resin Injection ground improvement for liquefaction mitigation at Poverty Bay Rugby Club, Gisborne
(2024-04-09)Gisborne is located near the Hikurangi Subduction Zone which contributes to a significant amount of the seismic activity in New Zealand. This coupled with Gisborne’s soil profile consisting of liquefiable sands has resulted ... -
Geotechnical design for severe liquefiable ground improvement with SCRR technique: Waikato case study
(2024-04-09)This paper introduces an innovative earthquake geotechnical design approach for severe liquefiable ground, adopting ground improvement using the patented Subsurface Compacted Rubble Raft (SCRR) technology in a Waikato ... -
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 ... -
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 ... -
Coordinating for Success - Enhancing Seismic Restraint Through Early Design Involvement
(2024-04-09)Tuhiraki is a new agricultural science facility for AgResearch Ltd., situated in Lincoln, Canterbury. The workplace and laboratory structures witnessed significant improvements in design efficiency and coordination of ... -
Recommended practice for seismic restraint design of suspended ceilings
(2024-04-09)Seismic restraint of suspended ceilings in the New Zealand environment has seen significant evolution over the past decade. Amendments to NZS1170.5 and updates to AS/NZS2785 are intended to drive better earthquake resilience ... -
Seismic response of frames with building cladding elements
(2024-04-09)This paper presents the concept, methodology and findings of the analysis of frames with building cladding elements exposed to seismic events. Inelastic nonlinear push-pull analyses, and hand analyses, are conducted to ... -
Evaluating and Communicating Seismic Risk for Low Rating Buildings
(2024-04-09)There are many challenges for owners and occupiers of buildings where seismic assessments produce ratings of less than 34%NBS, including addressing questions about whether they should continue to occupy the building. MBIE’s ... -
Residential Reconstruction of Christchurch City Centre: Is sustainability the key to promoting inner-city living?
(2024-04-09)The aftermath of the 12 years following the earthquake has posed persistent challenges in achieving attracting permanent residents into the Christchurch City Centre. Despite City Council’s initiatives like the Central City ... -
Impact of seismic demand on construction costs
(2024-04-09)The legally binding earthquake performance requirements in New Zealand's Building Act and Building Code emphasise building collapse prevention, allowing for a certain degree of damage to resist the seismic load. However, ... -
The role of risk perception, risk communication, and comparative risk principles in resilience building
(2024-04-09)Increasing resilience to earthquakes through choices such as building design requires people to understand, evaluate, and act on risk. Therefore, any communication efforts, either formal or informal, which are aimed at ... -
Rapid Earthquake Rupture Characterisation for New Zealand Using the FinDer Algorithm
(2024-04-09)For large and damaging earthquakes, rupture location and extent are critical inputs for impact forecasts and response decision-making. This information has the potential to significantly improve estimates of ground shaking, ... -
Implications for Design of Parts and Components from Updates to New Zealand Seismic Loading Standard and National Seismic Hazard Model
(2024-04-09)New Zealand engineering practitioners will see revisions to the seismic loading standards for non-structural elements (parts and components) in the draft technical specification TS1170.5. This paper considers the implications ... -
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 ... -
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 ... -
Time History Analysis is easy, and you should do it: Here’s how.
(2024-04-09)Time history analysis is generally regarded as a highly specialised and deeply technical process. There is also a growing divide between different schools of thought around how analysis should be done. On the one hand, ... -
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. ... -
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 ...
