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 ... -
Standardised timber moment-resisting frames for multistorey buildings
(2024-04-09)The paper presents preliminary findings from an extensive experimental testing campaign (Project Skyscraper) performed on full-scale moment-resisting timber frames intended for application in multistorey buildings. The ... -
Dynamic Shaking Layer models for large New Zealand earthquakes (M6.5+): from rapid source characterization to landslide and impact forecasting
(2024-04-09)GNS Science has developed a new Shaking Layers tool to rapidly deliver near-real time ground shaking maps for New Zealand, available directly through GeoNet. Shaking Layers combines observed strong motion data with ground ... -
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 ... -
Seismic Retrofitting Concrete Structures with Post-installed Connections in New Zealand
(2024-04-09)Seismic Retrofitting of concrete structures in New Zealand is of utmost importance, as highlighted by the most recent catastrophic Canterbury earthquakes in 2010 and 2011. With more than 2,800 earthquake-prone buildings ... -
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 ... -
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, ... -
Experimental Testing of Brittle RC frames Strengthened by RSFJ-toggle bracing system
(2024-04-09)This paper investigates the performance of the new retrofitting system, consisting of self-centering damper resilient slip friction joint (RSFJ)-toggle bracing system, as a global retrofitting method for deficient RC frame ... -
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 ... -
Improving structural performance of an existing EBF and moment frame structure using fluid viscous dampers
(2024-04-09)Improving the performance of existing buildings is a critical function for engineers and one of the most impactful ways we can improve the sustainability of buildings. By re-using and upgrading existing building stock, we ... -
