Seismic retrofitting of unreinforced masonry buildings using posttensioning has been the topic of many recent experimental research projects. However, the performance of such retrofit designs in actual design level earthquakes has previously been poorly documented. In 1984 two stone masonry buildings within The Arts Centre of Christchurch received posttensioned seismic retrofits, which were subsequently subjected to design level seismic loads during the 2010/2011 Canterbury earthquake sequence. These 26 year old retrofits were part of a global scheme to strengthen and secure the historic building complex and were subject to considerable budgetary constraints. Given the limited resources available at the time of construction and the current degraded state of the steel posttension tendons, the posttensioned retrofits performed well in preventing major damage to the overall structure of the two buildings in the Canterbury earthquakes. When compared to other similar unretrofitted structures within The Arts Centre, it is demonstrated that the posttensioning significantly improved the in-plane and out-of-plane wall strength and the ability to limit residual wall displacements. The history of The Arts Centre buildings and the details of the Canterbury earthquakes is discussed, followed by examination of the performance of the posttension retrofits and the suitability of this technique for future retrofitting of other historic unreinforced masonry buildings. http://www.aees.org.au/downloads/conference-papers/

The title reads 'CBD: High water table, flood/liquefaction risk...' The cartoon shows several Southern Right whales being used to ferry people around Christchurch City. Someone says 'Who needs light rail when you can have right whale!' Context: discussion about building a light rail system as a part of Christchurch post-earthquake development. Context: Several large Southern right whales have found Akaroa Harbour to their liking this week, sticking around rather than heading back south as part of their annual migration back to Antarctica. Quantity: 1 digital cartoon(s).

A video of Hon. Nicky Wagner, Associate Minister for Canterbury Earthquake Recovery, Hon. Lianne Dalziel, Mayor of Christchurch, and Peter Townsend, CEO of the Canterbury Employers' Chamber of Commerce, responding to questions from the floor during a panel at the 2016 Seismics in the City Conference. The panel has three themes:A City on the Move: Collaboration and Regeneration: "'Christchurch is now moving rapidly from the recovery phase into a regeneration stage with Central and Local Government working with the wider community, including the business community to ensure we get optimal outcomes for greater Christchurch' (CECC)."Looking Back: Remembering and Learning: "What are the milestones? What are the millstones? What have we learnt? What have we applied?"Looking Forward: Visioning and Building: "What do we aspire to? What are the roadblocks? What is the way forward?"

Please contact supervisor Lin Roberts at Lincoln University to request a copy of this dissertation to read.Cities around the world are becoming greener, with many striving to make their cities as green as possible. Christchurch was devastated by an Earthquake in 2011, which resulted in many fatalities. Though this impacted the city negatively, this sad event was used as an opportunity for the broken city to become a better one. The Christchurch City Council (CCC) ran an exercise called ‘Share an Idea’, which asked the public what they wanted the new city to look like. The main theme extrapolated by researchers was that people wanted the city to be greener. A draft plan was created by the CCC but was deemed not good enough and replaced by a new plan called the Blueprint Plan created by the government. Through the process of public consultation to the finalized plan and the implementation of the finalized plan, there were many changes made to the inclusion of nature into Central Christchurch’s urban regeneration. The aim of this research is to assess the role of nature in the urban regeneration of Christchurch, by evaluating the recovery process, and comparing the level of greenness the public wanted by looking at what they said in Share an Idea, and then seeing how that translated into the proposed plans, and then finally looking at what is being implemented.
