There are occasional sewerage spills into the Avon River while all the sewer and road repairs are carried out. This rock wall was level and well above high tide level prior to the eathquakes. All the houses that can been seen here (except for those on the distant Port Hills) are in the suburban "red zone" and are still to be demolished.

Between September 4, 2010 and December 23, 2011, a series of earthquakes struck the South Island of New Zealand including the city of Christchurch producing heavy damage. During the strongest shaking, the unreinforced masonry (URM) building stock in Christchurch was subjected to seismic loading equal to approximately 150-200% of code values. Post-earthquake reconnaissance suggested numerous failures of adhesive anchors used for retrofit connection of roof and floor diaphragms to masonry walls. A team of researchers from the Universities of Auckland (NZ) and Minnesota (USA) conducted a field investigation on the performance of new adhesive anchors installed in existing masonry walls. Variables included adhesive type, anchor diameter, embedment length, anchor inclination, and masonry quality. Buildings were selected that had been slated for demolition but which featured exterior walls that had not been damaged. A summary of the deformation response measured during the field tests are presented. AM - Accepted Manuscript

Its budget may have blown out by almost a third more than the original figure, but this weekend the doors to the Christchurch Town Hall will re-open for the first time since the 2011 earthquakes. It was touch and go whether the 47 year-old building would even be repaired after the 6.2 quake eight years ago today. 167-million-dollars later and the city is finally getting its town hall back. Conan Young was allowed inside for a sneak peak ahead of Saturday's official opening.

Reinforced concrete buildings that satisfied modern seismic design criteria generally behaved as expected during the recent Canterbury and Kaikoura earthquakes in New Zealand, forming plastic hinges in intended locations. While this meant that life-safety performance objectives were met, widespread demolition and heavy economic losses took place in the aftermath of the earthquakes.The Christchurch central business district was particularly hard hit, with over 60% of the multistorey reinforced concrete buildings being demolished. A lack of knowledge on the post-earthquake residual capacity of reinforced concrete buildings was a contributing factor to the mass demolition.Many aspects related to the assessment of earthquake-damaged reinforced concrete buildings require further research. This thesis focusses on improving the state of knowledge on the post earthquakeresidual capacity and reparability of moderately damaged plastic hinges, with an emphasis on plastic hinges typical of modern moment frame structures. The repair method focussed on is epoxy injection of cracks and patching of spalled concrete. A targeted test program on seventeen nominally identical large-scale ductile reinforced concrete beams, three of which were repaired by epoxy injection following initial damaging loadings, was conducted to support these objectives. Test variables included the loading protocol, the loading rate, and the level of restraint to axial elongation.The information that can be gleaned from post-earthquake damage surveys is investigated. It is shown that residual crack widths are dependent on residual deformations, and are not necessarily indicative of the maximum rotation demands or the plastic hinge residual capacity. The implications of various other types of damage typical of beam and column plastic hinges are also discussed.Experimental data are used to demonstrate that the strength and deformation capacity of plastic hinges with modern seismic detailing are often unreduced as a result of moderate earthquake induced damage, albeit with certain exceptions. Special attention is given to the effects of prior yielding of the longitudinal reinforcement, accounting for the low-cycle fatigue and strain ageing phenomena. A material-level testing program on the low-cycle fatigue behaviour of grade 300E reinforcing steel was conducted to supplement the data available in the literature.A reduction in stiffness, relative to the initial secant stiffness to yield, occurs due to moderate plastic hinging damage. This reduction in stiffness is shown to be correlated with the ductility demand,and a proposed model gives a conservative lower-bound estimate of the residual stiffness following an arbitrary earthquake-type loading. Repair by epoxy injection is shown to be effective in restoring the majority of stiffness to plastic hinges in beams. Epoxy injection is also shown to have implications for the residual strength and elongation characteristics of repaired plastic hinges.

Hundreds of children and 12 schools have pre-registered for swimming lessons at Christchurch's new Taiora QE2 sports centre, which opens today. The Canterbury earthquakes damaged the complex beyond repair, and almost six years after it was demolished, a new QE2 has risen from rubble - admittedly smaller and without the athletics track the old one was so well known for. Schools in particular are welcoming today's opening, after having to spend big bucks on transport to get their students to pools for lessons since the quakes. Logan Church reports.

A scathing inquiry into the Earthquake Commission's handling of the 2010 and 2011 Canterbury earthquakes could mean huge change for how it handles claims. The Government says it's committed to implementing all of the recommendations from the inquiry, including improving its communication, planning and preparedness and dispute resolution. John Goddard, an insurance and employment law barrister who dealt with more than 4000 claims at the time, says repairs were handled poorly and the new recommendations won't cover all the bases. John Goddard and Melanie Bourke of EQC Fix speak to Corin Dann.

A digitally manipulated image of two chairs sitting among rubble. The photographer comments, "There is a strip of land that has been declared as the red zone. This means that the houses facing towards the tidal estuary must be abandoned as they are on land that has been declared uneconomic to repair after the Christchurch earthquakes. These chairs are at the front of one of these properties that will be bulldozed. These seem to be saying come hell or high water we will not be moved".

Topics - it's been described as the 'Downton Effect' - a revival of more formal dinner parties as the British try to bring back fine dining. Today we learned that insurance companies have completed just 15 per cent of rebuilds and 10 per cent of over-cap repairs more than three years after the Canterbury earthquakes. A series of rallies are being held in five Australian cities today by New Zealanders protesting against legislation which denies them rights to welfare. Commuters are cautiously optimistic about a radical revamp proposed for Wellington's rush-hour rail service.

he 2016 Building (Earthquake Prone Building) Amendment Act aims to improve the system for managing earthquake-prone buildings. The proposed changes to the Act were precipitated by the Canterbury earthquakes, and the need to improve the seismic safety of New Zealand’s building stock. However, the Act has significant ramifications for territorial authorities, organisations and individuals in small New Zealand towns, since assessing and repairing heritage buildings poses a major cost to districts with low populations and poor rental returns on commercial buildings.
