Over 6.3 million waste tyres are produced annually in New Zealand (Tyrewise, 2021), leading to socioeconomic and environmental concerns. The 2010-11 Canterbury Earthquake Sequence inflicted extensive damage to ~6,000 residential buildings, highlighting the need to improve the seismic resilience of the residential housing sector. A cost-effective and sustainable eco-rubber geotechnical seismic isolation (ERGSI) foundation system for new low-rise buildings was developed by the authors. The ERGSI system integrates a horizontal geotechnical seismic isolation (GSI) layer i.e., a deformable seismic energy dissipative filter made of granulated tyre rubber (GTR) and gravel (G) – and a flexible rubberised concrete raft footing. Geotechnical experimental and numerical investigations demonstrated the effectiveness of the ERGSI system in reducing the seismic demand at the foundation level (i.e., reduced peak ground acceleration) (Hernandez et al., 2019; Tasalloti et al., 2021). However, it is essential to ensure that the ERGSI system has minimal leaching attributes and does not result in long-term negative impacts on the environment.
Two people stare at a demolition scene. The man thinks there must have been an earthquake but the woman advises him that it was the city council. Refers to plans to demolish three buildings in Wellington's Willis Street without public consultation. The buildings due for demolition are owned by Singaporean Grand Complex Properties, which plans eventually to build a multimillion-dollar high-rise on the site, reports stuff.co.nz. The Canterbury earthquake happened 4th September and as a result there has been a lot of discussion about the need to preserve historic buildings if at all possible. Quantity: 1 digital cartoon(s).
At 12.51pm it will be 10 years since a devastating 6.2 earthquake struck Ōtautahi Christchurch, bringing down buildings and killing 185 people. A National service will get underway at half-past-12 at the city's Canterbury Earthquake Memorial site, to mark the anniversary. Maurice Gardiner's sister, Donna Manning, died in the CTV building collapse. Mr Gardiner told Māni Dunlop that at the Avonhead Cemetery this morning, he and his family joined others who have whānau buried there for a private service, where they remembered those they lost 10 years ago.
The effects of soil-foundation-structure interaction (SFSI) have been a topic of discussion amongst the structural and geotechnical community for many decades. The complexity of the mechanisms, as well as the need for inter-disciplinary knowledge of geotechnical and structural dynamics has plagued the advancement and the consequent inclusion of SFSI effects in design. A rigorous performance-based design methodology should not just consider the performance of the superstructure but the supporting foundation system as well. Case studies throughout history (eg. Kobe 1995, Kocaeli 1999 and Christchurch earthquakes 2010-2011) have demonstrated that a poor performance at the foundation level can result in a full demolition of the structure and, in general terms, that the extent of damage to, and repairability of, the building system as a whole, is given by the combination of the damage to the soil, foundation and superstructure. The lack of consideration of the modifying factors of SFSI and an absence of intuitive performance levels for controlling foundation and soil behaviour under seismic loads has resulted in inadequate designs for buildings sited on soft soil. For engineers to be satisfied that their designs meet the given performance levels they must first, understand how SFSI affects the overall system performance and secondly have tools available to adequately account for it in their design/assessment. This dissertation presents an integrated performance-based design procedure for buildingfoundation systems that considers all of the major mechanisms of SFSI. A new soil-foundation macro-element model was implemented into a nonlinear finite element software and validated against several experimental tests. The numerical model was used to provide insights in to the mechanisms of SFSI and statistical analysis on the results yielded simple expressions that allow the behaviour to be quantified. Particular attention was paid to the effects of shear force on the foundation response and the quantification of the rocking mode of response. The residual deformations of the superstructure and distribution of forces up the structure were also investigated. All of the major SFSI mechanisms are discussed in detail and targeted numerical studies are used to explain and demonstrate concepts. The design procedure was validated through the design and assessment of a series of concrete buildings that were designed to account for the effects of SFSI.
An experienced builder says he couldn't wait to get out of the Canterbury Television Building after seeing how damaged it was in the September 2010 earthquake.
Churches are an important part of New Zealand's historical and architectural heritage. Various earthquakes around the world have highlighted the significant seismic vulnerability of religious buildings, with the extensive damage that occurred to stone and clay-brick unreinforced masonry churches after the 2010-2011 Canterbury earthquakes emphasising the necessity to better understand this structural type. Consequently, a country-wide inventory of unreinforced masonry churches is here identified. After a bibliographic and archival investigation, and a 10 000 km field trip, it is estimated that currently 297 unreinforced masonry churches are present throughout New Zealand, excluding 12 churches demolished in Christchurch because of heavy damage sustained during the Canterbury earthquake sequence. The compiled database includes general information about the buildings, their architectural features and structural characteristics, and any architectural and structural transformations that have occurred in the past. Statistics about the occurrence of each feature are provided and preliminary interpretations of their role on seismic vulnerability are discussed. The list of identified churches is reported in annexes, supporting their identification and providing their address.

The video also includes a tour of the Arts Centre, including the Boys' High School swimming pool and gymnasium which was exposed after another building was demolished.

An exceedingly large 'Gerry' Brownlee, the Minister for Earthquake Recovery, rises from a chair, holding a briefcase labeled 'CERA' and calling for 'Bob' Parker, the mayor of Christchurch. The thin Parker was flattened against Brownlee's enormous rear, when Brownlee sat on the chair. Brownlee and Parker had a strained relationship, with the government taking an increasing amount of control in local decision making. After ongoing assurances by Parker that Christchurch City Council would meet all of International Accreditation New Zealand's requirements on issuing building consents, Brownlee announced in June 2013 without Parker's prior knowledge that the authority had withdrawn its accreditation.
