Testing the cyclic strain softening behaviour of an ageing puddled clay core dam
(2024-04-09)Seismic resilience of the 150-year-old Ross Creek puddled clay core water supply dam in Dunedin has recently been enhanced through a programme of refurbishment. The very low permeability moderately plastic soils comprising ... -
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 ... -
The ROBUST Steel Building Response
(2024-04-09)The ROBUST test programme describes the full-scale shaking table testing of nine different steel frame building configurations on the Tongji University shaking tables. Energy dissipation occurs by means of friction devices ... -
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 ... -
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 ... -
Finite Element Method Analysis of Reinforced Concrete Exterior Beam-Column Joint Structures Subjected to High Varying Axial Forces
(2024-04-09)Large variation of axial forces in columns in the lower stories of a high-rise reinforced concrete buildings during a severe earthquake can cause significant changes in the column-to-beam strength ratio in the exterior ... -
Shallow Shear Wave Reflection Surveys in the Wellington CBD
(2024-04-09)Seismic reflection profiles using shear waves provide constraints on the thickness of sediments beneath the Wellington CBD. New shear wave source and acquisition methods were trialled for use in urban environments to ... -
Towards 3D ground motion simulation-based site amplification: a Wellington case study considering multiple basin geometries
(2024-04-09)This paper presents a study on 3D ground motion simulation-based site amplification using the Wellington region of New Zealand as a case study. Several recent models of the Wellington sedimentary basin have been developed ... -
Proposal of repair index and strategy for recovery of reinforced concrete buildings damaged by earthquakes
(2024-04-09)Restoration of damaged buildings is an important issue for achieving smooth recovery of society after a devastating earthquake disaster. In general, in past earthquake disasters in Japan, demolition or repair judgement was ... -
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, ... -
Heritage Buildings and Community Sense of Place: Towards Addressing the Challenge of Earthquake Prone Heritage Buildings
(2024-04-09)New Zealand is a nation that has a significant amount of built heritage, of which there are several internationally recognised landmarks, including the Christchurch Cathedral, the Church of the Good Shepherd, and the Chateau ... -
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 ... -
Highbank Power Station Redevelopment – Design Process for a Concrete Encased Turbine and Generator Plinth Replacement
(2024-04-09)Manawa Energy, a renewable energy provider in New Zealand, operates a network of 26 power schemes from the Bay of Plenty in the North to Otago in the South. The Highbank Power Station stands as one of Manawa’s highest ... -
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 ... -
Turnbull Library: Strengthening for Heritage and Resilience
(2024-04-09)Turnbull House is a Category 1 Heritage building on Bowen Street in Wellington. It was built in the 1910s as a residence and library, primarily from unreinforced masonry. Although some strengthening was carried out in the ... -
Seismic Performance of Prefabricated Modular Mass Timber Structures with Inter-Story Isolation.
(2024-04-09)Prefabricated Modular Mass Timber (MMT) construction provides an alternative to traditional on-site light timber construction. MMT buildings comprise of prefabricated volumetric modules assembled on-site to form a larger, ... -
Effective and economic combination of seismic isolation and vibration insulation within one innovative device
(2024-04-09)Seismic isolation is a well-known approach to reduce the risk of casualties as well as structural and content damage due to earthquakes. Vibration insulation on the other hand is increasingly a requirement in urban areas ... -
Prediction of crack widths in NZS 3101 and its significance in the seismic design of connections
(2024-04-09)Cracking of reinforced concrete structures due to bending or tension has usually great significance on structural behaviour. Design codes limit crack widths for durability and aesthetic purposes. The research of cracking ... -
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 ... -
Evaluating the Effect of Initial Gravity Forces in Buckling-Restrained Brace Frame Braces
(2024-04-09)It is common practice to design buckling-restrained braces (BRBs) for seismic forces only, and to neglect any initial gravity that occurs in them. This practice assumes that these gravity loads simply “shed” upon first ...
