The cartoon shows two images of cars nose-down in ditches, the first is caused by 'liquifaction' and the second by 'stupifaction'. Context: there was another large aftershock on Boxing Day in Christchurch which resulted in quite a lot of liquefaction. There is always concern over the Christmas holidays about drinking while driving. Other Titles - Liquefaction Quantity: 1 digital cartoon(s).

A video about the reopening of Alice in Videoland, in the back of the former Post Office on the corner of Tuam and High Streets. The redesigned space has allowed Alice in Videoland to expand from a DVD rental store to include an art-house cinema as well.

Text reads 'Pet of the day... ' Below is a notice tacked to a wall which has an image of a cat wearing spectacles on it. Text reads 'LOST. Large moggy, last seen roaming in Christchurch. Answers to the name of "Gerry" or "Dinners ready". Has a loud purr, looks cuddly but can turn...' Context: This is a reference to Gerry Brownlee, the Minister for Earthquake Recovery. When National announced its offer based on the 2007 rating valuation to red-zone property owners on 23 June, Gerry Brownlee specifically told people who had made improvements between the time of the valuation and the September quake to 'keep their receipts'. The offer from CERA dated August 19 now says quite clearly that people can only seek an adjustment to the purchase price if the rating valuation is based on an incorrect floor area, or if 'you have received a code compliance certificate for consented building work undertaken after the rating valuation and that work increased the floor area of your house'.

Canterbury novelist Joanna Orwin has a new, futurist story of a New Zealand changed by cataclysmic volcanoes and tsunami, Sacrifice. And we hear about some of the stories in a post-earthquake Christchurch anthology, Tales for Canterbury.

A video of an interview with Andy Dodd, archaeologist at Underground Overground Archaeology, and Rewi Couch, representative for Te Hapu o Ngai Te Wheke, about the excavation of the site of the former Lyttelton Post Office on Norwich Quay. A Maori adze was found by the archaeologists deep beneath the concrete foundations of the building. The adze is a woodworking tool which indicates that early Maori settlers may have carved and launched waka on the site.

An extensive research program is on-going at the University of Canterbury, New Zealand to develop new technologies to permit the construction of multi-storey timber buildings in earthquake prone areas. The system combines engineered timber beams, columns and walls with ductile moment resisting connections using post-tensioned tendons and eventually energy dissipaters. The extensive experimental testing on post-tensioned timber building systems has proved a remarkable lateral response of the proposed solutions. A wide number of post-tensioned timber subassemblies, including beam-column connections, single or coupled walls and column-foundation connections, have been analysed in static or quasi-static tests. This contribution presents the results of the first dynamic tests carried out with a shake-table. Model frame buildings (3-storey and 5-storey) on one-quarter scale were tested on the shake-table to quantify the response of post-tensioned timber frames during real-time earthquake loading. Equivalent viscous damping values were computed for post-tensioned timber frames in order to properly predict their response using numerical models. The dynamic tests were then complemented with quasi-static push and pull tests performed to a 3-storey post-tensioned timber frame. Numerical models were included to compare empirical estimations versus dynamic and quasi-static experimental results. Different techniques to model the dynamic behaviour of post-tensioned timber frames were explored. A sensitivity analysis of alternative damping models and an examination of the influence of designer choices for the post-tensioning force and utilization of column armouring were made. The design procedure for post-tensioned timber frames was summarized and it was applied to two examples. Inter-storey drift, base shear and overturning moments were compared between numerical modelling and predicted/targeted design values.

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.
