As part of the 'Project Masonry' Recovery Project funded by the New Zealand Natural Hazards Research Platform, commencing in March 2011, an international team of researchers was deployed to document and interpret the observed earthquake damage to masonry buildings and to churches as a result of the 22nd February 2011 Christchurch earthquake. The study focused on investigating commonly encountered failure patterns and collapse mechanisms. A brief summary of activities undertaken is presented, detailing the observations that were made on the performance of and the deficiencies that contributed to the damage to approximately 650 inspected unreinforced clay brick masonry (URM) buildings, to 90 unreinforced stone masonry buildings, to 342 reinforced concrete masonry (RCM) buildings, to 112 churches in the Canterbury region, and to just under 1100 residential dwellings having external masonry veneer cladding. In addition, details are provided of retrofit techniques that were implemented within relevant Christchurch URM buildings prior to the 22nd February earthquake and brief suggestions are provided regarding appropriate seismic retrofit and remediation techniques for stone masonry buildings. http://www.nzsee.org.nz/publications/nzsee-quarterly-bulletin/

Currently there is a worldwide renaissance in timber building design. At the University of Canterbury, new structural systems for commercial multistorey timber buildings have been under development since 2005. These systems incorporate large timber sections connected by high strength post-tensioning tendons, and timber-concrete composite floor systems, and aim to compete with existing structural systems in terms of cost, constructability, operational and seismic performance. The development of post-tensioned timber systems has created a need for improved lateral force design approaches for timber buildings. Current code provisions for seismic design are based on the strength of the structure, and do not adequately account for its deformation. Because timber buildings are often governed by deflection, rather than strength, this can lead to the exceedence of design displacement limitations imposed by New Zealand codes. Therefore, accurate modeling approaches which define both the strength and deformation of post-tensioned timber buildings are required. Furthermore, experimental testing is required to verify the accuracy of these models. This thesis focuses on the development and experimental verification of modeling approaches for the lateral force design of post-tensioned timber frame and wall buildings. The experimentation consisted of uni-direcitonal and bi-directional quasi-static earthquake simulation on a two-thirds scale, two-storey post-tensioned timber frame and wall building with timber-concrete composite floors. The building was subjected to lateral drifts of up to 3% and demonstrated excellent seismic performance, exhibiting little damage. The building was instrumented and analyzed, providing data for the calibration of analytical and numerical models. Analytical and numerical models were developed for frame, wall and floor systems that account for significant deformation components. The models predicted the strength of the structural systems for a given design performance level. The static responses predicted by the models were compared with both experimental data and finite element models to evaluate their accuracy. The frame, wall and floor models were then incorporated into an existing lateral force design procedure known as displacement-based design and used to design several frame and wall structural systems. Predictions of key engineering demand parameters, such as displacement, drift, interstorey shear, interstorey moment and floor accelerations, were compared with the results of dynamic time-history analysis. It was concluded that the numerical and analytical models, presented in this thesis, are a sound basis for determining the lateral response of post-tensioned timber buildings. However, future research is required to further verify and improve these prediction models.

The extent of liquefaction in the eastern suburbs of Christchurch (Aranui, Bexley, Avonside, Avonhead and Dallington) from the February 22 2011 Earthquake resulted in extensive damage to in-ground waste water pipe systems. This caused a huge demand for portable toilets (or port-a-loos) and companies were importing them from outside Canterbury and in some instances from Australia. However, because they were deemed “assets of importance” under legislation, their allocation had to be coordinated by Civil Defence and Emergency Management (CDEM). Consequently, companies supplying them had to ignore requests from residents, businesses and rest homes; and commitments to large events outside of the city such as the Hamilton 400 V8 Supercars and the Pasifika Festival in Auckland were impacted. Frustrations started to show as neighbourhoods questioned the equity of the port-a-loos distribution. The Prime Minister was reported as reassuring citizens in the eastern suburbs in the first week of March that1 “a report about the distribution of port-a-loos and chemical toilets shows allocation has been fair. Key said he has asked Civil Defence about the distribution process and where the toilets been sent. He said there aren’t enough for the scale of the event but that is quickly being rectified and the need for toilets is being reassessed all the time.” Nonetheless, there still remained a deep sense of frustration and exclusion over the equity of the port-a-loos distribution. This study took the simple approach of mapping where those port-a-loos were on 11-12 March for several areas in the eastern suburbs and this suggested that their distribution was not equitable and was not well done. It reviews the predictive tools available for estimating damage to waste water pipes and asks the question could this situation have been better planned so that pot-a-loo locations could have been better prioritised? And finally it reviews the integral roles of communication and monitoring as part of disaster management strategy. The impression from this study is that other New Zealand urban centres could or would also be at risk and that work is need to developed more rational management approaches for disaster planning.

Christchurch City has to be rebuilt after the earthquakes of 4 September 2010 and 22 February 2011. People are being invited to contribute ideas about how to rebuild on a city council website. A group of people look at ideas on computers; a boy comments that 'this one looks just like the old city' and his father comments 'but built fifty miles up the road!' A woman looks at what appears to be pre European Maori pa site and says 'Hone Harawira wants something pre-European!' Another woman looks at a map of the middle of the South Island and says 'Rodney Hide doesn't care as long as Christchurch combines with Timaru and Westport!' Context - Former ACT leader Rodney Hide in his role as Minister for Local Government likes 'supercities' and Hone Harawira has left the Maori Party, fed up with the compromises he believes they have to make to suit their coalition agreement with the National government. He seems to prefer a city that will reflect simpler pre-European times. Colour and black and white versions available Quantity: 2 digital cartoon(s).

There is a critical strand of literature suggesting that there are no ‘natural’ disasters (Abramovitz, 2001; Anderson and Woodrow, 1998; Clarke, 2008; Hinchliffe, 2004). There are only those that leave us – the people - more or less shaken and disturbed. There may be some substance to this; for example, how many readers recall the 7.8 magnitude earthquake centred in Fiordland in July 2009? Because it was so far away from a major centre and very few people suffered any consequences, the number is likely to be far fewer than those who remember (all too vividly) the relatively smaller 7.1 magnitude Canterbury quake of September 4th 2010 and the more recent 6.3 magnitude February 22nd 2011 event. One implication of this construction of disasters is that seismic events, like those in Canterbury, are as much socio-political as they are geological. Yet, as this paper shows, the temptation in recovery is to tick boxes and rebuild rather than recover, and to focus on hard infrastructure rather than civic expertise and community involvement. In this paper I draw upon different models of community engagement and use Putnam’s (1995) notion of ‘social capital’ to frame the argument that ‘building bridges’ after a disaster is a complex blend of engineering, communication and collaboration. I then present the results of a qualitative research project undertaken after the September 4th earthquake. This research helps to illustrate the important connections between technical rebuilding, social capital, recovery processes and overall urban resilience.

The cartoon shows Christchurch obscured by ash. Text reads 'Christchurch recovery package' and below are the words 'Cash cloud'. Context - Beginning on the 6th of June the Puyehue-Cordon Caulle volcano has been erupting for more than a week. Drifting ash clouds have been interupting flights. On Thursday 23 June Prime Minister John Key, Canterbury Earthquake Recovery Minister Gerry Brownlee and representatives from engineering consultants Tonkin & Taylor announced the first part of the Government's long-awaited land report that revealed the fate of up to 5000 quake-damaged homes. These homes were in the 'red zone'. But 10,500 owners in the orange zone were left in limbo, with their properties requiring further assessment. One of the options presented to residents in the red zone, ideal for people with replacement policies, was the government bought your land, and you dealt directly with your insurers about your house. However they got a shock when insurers told them they won't replace their homes, they'll only repair them, even though they're earmarked for certain demolition. Quantity: 1 digital cartoon(s).

An often overlooked aspect of urban housing development is the composition of the space between buildings; the streetscape. The pressures of suppressing suburban sprawl have seen housing developments respond by increasing residential density within more centralised city sites. Medium-density housing typologies are often used as urban infill in response to the challenge of accommodating an increasing population. A by-product of these renewed areas is the creation of new open space which serves as the fundamental public space for sociability to develop in communities. Street space should emphasise this public expression by encouraging social exchange and interaction. As a result, a neighbourhood owes its liveliness (or lack thereof) to its streets. The issue of density when applied to the urban housing landscape encompasses two major components: the occupancy of both the private realms, constituting the residential built form, and the public spaces that adjoins them, the streets. STREETSCAPE: dialogues of street + house. Continual transition between the realms of public and private (building and street space) enact active edges, giving way to public stimulation; the opportunity for experiencing other people. The advent of seeing and hearing other people in connection with daily comings and goings encourages social events to evolve, enhancing the notion of neighbourly conduct. Within New Zealand, and specifically in Christchurch as considered here, the compositions of current streetscapes lack the demeanor to really encourage and facilitate the idea of neighbourly interaction and public expression. Here lies the potential for new street design to significantly heighten the interplay of human activity. In response, this research project operates under the notion that the street spaces of urban residential areas are largely underutilised. This lack is particularly evident in the street. Street design should strive to produce spaces which stimulate the public life of residents. There exists a need to reassert eminence of the street as a space for vibrant neighbourhood life. This thesis employs design as a tool for researching and will involve using numerous concept generators to trigger the production of multiple scenarios. These scenarios are to explore the ways in which the streetscapes within medium-density urban communities could respond in the event of (re) development.

Surface rupture of the previously unrecognised Greendale Fault extended west-east for ~30 km across alluvial plains west of Christchurch, New Zealand, during the Mw 7.1 Darfield (Canterbury) earthquake of September 2010. Surface rupture displacement was predominantly dextral strike-slip, averaging ~2.5 m, with maxima of ~5 m. Vertical displacement was generally less than 0.75 m. The surface rupture deformation zone ranged in width from ~30 to 300 m, and comprised discrete shears, localised bulges and, primarily, horizontal dextral flexure. About a dozen buildings, mainly single-storey houses and farm sheds, were affected by surface rupture, but none collapsed, largely because most of the buildings were relatively flexible and resilient timber-framed structures and also because deformation was distributed over a relatively wide zone. There were, however, notable differences in the respective performances of the buildings. Houses with only lightly-reinforced concrete slab foundations suffered moderate to severe structural and non-structural damage. Three other buildings performed more favourably: one had a robust concrete slab foundation, another had a shallow-seated pile foundation that isolated ground deformation from the superstructure, and the third had a structural system that enabled the house to tilt and rotate as a rigid body. Roads, power lines, underground pipes, and fences were also deformed by surface fault rupture and suffered damage commensurate with the type of feature, its orientation to the fault, and the amount, sense and width of surface rupture deformation.

The scene shows a tract of land with a jagged crack running through it. An arm representing the 'Council' reaches out of the crack and points a finger. Someone from the 'Tibetan Community' whose head cannot be seen says 'Surely you can lift finger higher than that?' Context: The Dalai Lama visited Christchurch after the earthquakes but The Dalai Lama's New Zealand representative is accusing the Christchurch City Council of snubbing the spiritual leader during his visit, suggesting ties with China are to blame. In a letter to Christchurch Mayor Bob Parker, New Zealand Tibetan community representative Thuten Kesang said he was disappointed the council "did not lift a finger to help" the Dalai Lama during his visit to the earthquake-hit city in June. Christchurch has a sister-city relationship with the Chinese Gansu Province and Wuhan City. Kesang said he believed this relationship made the council reluctant to engage with the exiled Tibetan leader. (Press - 10 August 2011) Quantity: 1 digital cartoon(s).
