Detail of the Christchurch Anglicain Cathedral viewed from a path between the new Cashel Mall shopping area and Cathedral Square which was opened two weekends ago. This is the first time this section of the city has been open to the public since the 22 February 2011 earthquake. It will be closed off again after 11 December 2011 for the demolitio...

Broken stained glass in a window of the ChristChurch Cathedral. The photographer comments, "I only managed to get one picture of the badly earthquake damaged Christchurch Cathedral and I did not want to get the buttresses holding it up like some Medieval siege engine, so I thought this one was perfect. Looking through the window notice that the adjacent wall has gone and the blue windows belong to an office block across the road".

Broken windows on Leicester House. Broken filing cabinets and other fittings lie on the ground in front of the building. The photographer comments, "As you can see the game did not last very long".

A video of an interview with stonemason Mark Whyte, about the demolition of the Holy Trinity Church in Avonside. Whyte discusses how the building should have been deconstructed slowly in order to salvage unique heritage material such as stained-glass windows and hand-painted ceilings.

The damaged clock tower on Victoria Street, wrapped and braced to prevent further damage. The photographer comments, "Diamond Jubilee Clock Tower in Christchurch. Its legs wrapped up for protection. Volcanic stone and limestone clock tower with ornate wrought iron work with coloured glass around part of the tower and four clock faces. Clock Tower built in this location to commemorate the Diamond Jubilee of Queen Victoria. Has two white marble plaques and one bronze plaque set on stone work above arches".

Text at the top of the cartoon reads 'NZ city strengthening?' A whole city enclosed in a glass dome and balanced on huge springs intended to make it earthquake resistant rocks as another aftershock hits. Context - Two earthquakes and hundreds of aftershocks have hit Christchurch, the first on 4 September 2010 and a second more devastating one on 22 February 2011. There has been great emphasis on making heritage buildings that are rebuilt and all new buildings earthquake resistant. The example in the cartoon is perhaps a Springs-with-damper base isolator.

In the living room of a house half-ruined by the Christchurch earthquake a decrepit and useless-looking man in a grubby white singlet doses in his armchair with a glass of beer in his hand; his wife whispers to a friend 'Just between you and me, I'm hoping to have him red-stickered!' Context - The two Christchurch earthquakes of 4 September 2010 and 22 February 2011 and the technique of using different coloured stickers to designate the degree of damage to buildings - 'red' indicates that it needs to be demolished. Colour and black and white versions available Quantity: 2 digital cartoon(s).

An as-built reinforced concrete (RC) frame building designed and constructed according to pre-1970s code design construction practice has been recently tested on the shake table at the University of Canterbury. The specimen, 1/2.5 scaled version of the original prototype, consists of two 3-storey 2-bay asymmetric frames in parallel, one interior and one exterior, jointed together by transverse beams and floor slabs. Following the benchmark test, a retrofit intervention has been proposed to rehabilitate the tested specimen. In this paper, detailed information on the assessment and design of the seismic retrofit procedure using GFRP (glass fibre reinforced polymer) materials is given for the whole frame. Hierarchy of strength and sequence of events (damage mechanisms) in the panel zone region are evaluated using a moment-axial load (M-N) interaction performance domain, according to a performance-based retrofit philosophy. Specific limit states or design objectives are targeted with attention given to both strength and deformation limits. In addition, an innovative retrofit solution using FRP anchor dowels for the corner beam-column joints with slabs is proposed. Finally, in order to provide a practical tool for engineering practice, the retrofit procedure is provided in a step-by step flowchart fashion.

Text above the image reads 'Time capsules unearthed in Christchurch' A man reads a newspaper which says 'Petrol is so cheap you can actually afford to run one of these new-fangled motor cars...' Context - when a bronze statue of Christchurch founder John Robert Godley, which stood in Cathedral Square, toppled during the Christchurch earthquake of 22 February 2011, a crane driver clearing rubble discovered two time capsules. One is a small glass capsule with a hand-written letter on gold parchment inside, while the other is a large metal-like object, yet to be opened. A Nelson newspaper 'The Colonist' in an article published in 1918, about the time capsule in Christchurch said, "This statute of John Robert Godley executed by Thomas Woolner was erected in the west side of the Cathedral Square by the Provincial Government of Canterbury, and unveiled by the late Sir Charles Christopher Bowen on August 6 1867, it was moved to this site in March 1918." The man in the cartoon reads a bout the cost of petrol being incredibly cheap and thinks it refers to today's prices. Quantity: 1 digital cartoon(s).
