A photograph captioned, "After the September earthquake, it was more a simple case of something gets broken and it gets repaired. Then came February, and June as well, and suddenly it's just not so straightforward anymore".

Articles, Christchurch uncovered

During recent earthquake repairs at a residential property on well-known Sumner Road in Lyttelton, our archaeologists uncovered a small assemblage of artefacts that represented everyday Victorian household items. At first glance these appeared a somewhat ordinary – but when Lydia … Continue readi...

In order to provide information related to seismic vulnerability of non-ductile reinforced concrete (RC) frame buildings, and as a complementary investigation on innovative feasible retrofit solutions developed in the past six years at the University of Canterbury on pre-19170 reinforced concrete buildings, a frame building representative of older construction practice was tested on the shake table. The specimen, 1/2.5 scale, consists of two 3-storey 2-bay asymmetric frames in parallel, one interior and one exterior, jointed together by transverse beams and floor slabs. The as-built (benchmark) specimen was first tested under increasing ground motion amplitudes using records from Loma Prieta Earthquake (California, 1989) and suffered significant damage at the upper floor, most of it due to lap splices failure. As a consequence, in a second stage, the specimen was repaired and modified by removing the concrete in the lap splice region, welding the column longitudinal bars, replacing the removed concrete with structural mortar, and injecting cracks with epoxy resin. The modified as-built specimen was then tested using data recorded during Darfield (New Zealand, 2010) and Maule (Chile, 2010) Earthquakes, with whom the specimen showed remarkably different responses attributed to the main variation in frequency content and duration. In this contribution, the seismic performance of the three series of experiments are presented and compared.

Text reads 'Solution to Christchurch sewage problems?...' A woman, with a roll of toilet paper in her hand, climbs a ladder to a toilet that is positioned on a sewage pipe high above the ground. There are further toilets at intervals on the pipe. Her husband stands in the garden and observes that it is 'Easy to access and easy to repair'. Context - the Christchurch earthquakes and continuing aftershocks have done huge damage to sewage infrastructures which suggests having the pipes above ground as a solution.

The title reads 'Future Christchurch CBD?...' Two people stare at numerous large featureless blocks across the Avon River. One says 'Those buildings look pretty ugly' and the other points out that they are 'just the piles'. Context: The Christchurch City Council is moving to impose urban-design etiquette and avert architectural mistakes such as clashing with the neighbours, glaring corporate colours and the long, blank walls common to most suburban shopping malls. The proposed rules will be overseen by an urban-design panel of four experts drawn from a pool of 12 architects, designers, planners and valuers. Quantity: 1 digital cartoon(s).
