One of the failure modes that got the attention of researchers in the 2011 February New Zealand earthquake was the collapse of a key supporting structural wall of Grand Chancellor Hotel in Christchurch which failed in a brittle manner. However, until now this failure mode has been still a bit of a mystery for the researchers in the field of structural engineering. Moreover, there is no method to identify, assess and design the walls prone to such failure mode. Following the recent break through regarding the mechanism of this failure mode based on experimental observations (out-of-plane shear failure), a numerical model that can capture this failure was developed using the FE software DIANA. A comprehensive numerical parametric study was conducted to identify the key parameters contributing to the development of out-of-plane shear failure in reinforced concrete (RC) walls. Based on the earthquake observations, experimental and numerical studies conducted by the authors of this paper, an analytical method to identify walls prone to out-of-plane shear failure that can be used in practice by engineers is proposed. The method is developed based on the key parameters affecting the seismic performance of RC walls prone to out-of-plane shear failure and can be used for both design and assessment purposes

Shows a postman who has just put an 'Earthquake bill' for '$8.5 billion' into the government's letterbox. Context - The New Zealand government will spend about 8.5 billion NZ dollars (6.6 billion U.S. dollars) over the next few years rebuilding Christchurch. New Zealand Finance Minister Bill English said on Tuesday that the Treasury has estimated the direct cost of the two earthquakes is about 5.5 billion NZ dollars), which will be fully provided for in the Budget in May. He said about 3 billion NZ dollars of that relates to thegovernment's share of local government infrastructure, roads, insurance excesses on schools and housing, land remediation from the September quake, demolition, Accidents Compensation Corporation scheme and the business support package.

Text reads 'City's old chimneys are considered the no. 1 earthquake danger'. Below are several angry-looking chimneys which sing 'Chim chim-in-ey. Chim chim-in-ey, chim chim cher-oo! When the big shake's on - we're coming to get you!' Context - Invercargill City council building services manager Simon Tonkin has seen first-hand the massive damage falling chimneys inflicted on homes and nearby vehicles following the massive Christchurch quake, and says that Invercargill's old brick chimneys are the No1 danger to the city's residents and homes if a major earthquake strikes and should be removed if they are not being used.

In a series of five out of six caricatures Christchurch Mayor Bob Parker shows photographs of himself helping people hurt by the 4th September earthquake and helping Christchurch after the earthquake. In the sixth caricature he disingenuously smirks and says that he has been so busy helping Christchurch that he forgot about the Mayoral election; he then affects a philosophical stance about his chances. Refers to the advantage that the earthquake of 4th September has given the incumbent mayor Bob Parker in the local body elections of 9th October. Black and white and colour versions of this cartoon are available Quantity: 2 digital cartoon(s).

Text top left reads 'Downsizemic activity' and a seismic graph zigzags wildly but gradually tails off into the words 'Interest rates' which take a serious downwards trend. Context - The Christchurch earthquakes of 4 September 2010 and 22 February 2011 which have had an impact on an already stagnating economy. The Reserve Bank has made a relatively large 50-point cut in its benchmark interest rate, the Official Cash Rate (from 3% to 2.5 per cent). Critics say that inflation is already running unacceptably high and there is a threat of much higher inflation in a year or two when the rebuilding of Christchurch begins to put pressure on limited resources. The Reserve Bank acknowledged these factors, but it has chosen instead to focus on the immediate impact of the earthquake on the economy and particularly on all-important business and consumer sentiment.
