Observations in major earthquakes have shown that rockable structures suffered less to no damage. During rocking, that is, partial and temporary footing separations, the influx of seismic energy is interrupted and thus the impact of the base excitation is reduced. Rocking causes the structure to deform more rigid like. Consequently, the structure experiences less deformation along the height and thus a lower damage potential. Although many researchers have studied the influence of rockable footings, most of these are either analytical or numerical, and only a very few structures have been built with rockable footings worldwide, for example, the chimney at Christchurch Airport and the South Rangitikei Viaduct in New Zealand. Despite these studies, a thorough and understanding is not yet available, especially with respect to experimental validations. This work is the first to investigate the rocking behaviour of bridges with different slenderness using large‐scale shake table experiments. To limit the number of influence factors, a stiff footing support and the same fixed‐base fundamental frequency of the bridges were assumed. The result shows that the girder displacement and the footing rotation of the tall bridge do not always move in phase, which cannot be observed in the short bridge. The results demonstrate the important role of slenderness in the overall responses of rockable bridges. This behaviour cannot be observed in bridges with a commonly assumed fixed base since the slenderness effect cannot be activated.

University of Canterbury Vice-Chancellor Rod Carr conferring with former Chancellor Rex Williams, inside the UCSA's "Big Top" tent. The tent was erected in the UCSA car park to provide support for students in the aftermath of the 22 February 2011 earthquake. Around them students have gathered to watch a local musician play. The student have spent the day clearing liquefaction from Christchurch properties as part of the Student Volunteer Army.

The ruins of the historic Durham Street Methodist Church in the aftermath of the 22 February 2011 earthquake. The only parts of the building still upright are those supported by steel braces placed there after the 4 September 2010 earthquake to strengthen the building as it awaited repairs. Rubble has spilled out onto the street, knocking over the safety fences that were also erected after September. Silt from liquefaction has covered the road around the church.

A photograph of Ashleigh (left), Nigel (back), Chantal (front) and Kadyn Palmer (right) in front of their former Kaiapoi residence. The photograph was taken by Cosmo Kentish-Barnes for Still Here, an artistic project supported by All Right?. Kentish-Barnes produced a series of photographs of exiled residents, accompanied with a first-person account of their life since the earthquakes.

An image designed to promote the 'Write Now' 2014 young writers workshops. Some of the best pieces from the workshop were published in a chapbook and on posters for the Christchurch 2014 WORD Festival. The workshops were supported by All Right?, Christchurch City Libraries and The School for Young Writers. All Right? posted the image on their Facebook page on 15 July 2014 at 4:31pm.

Abstract This study provides a simplified methodology for pre-event data collection to support a faster and more accurate seismic loss estimation. Existing pre-event data collection frameworks are reviewed. Data gathered after the Canterbury earthquake sequences are analysed to evaluate the relative importance of different sources of building damage. Conclusions drawns are used to explore new approaches to conduct pre-event building assessment.

A sign on a fence on Marine Parade in North New Brighton reads "We need your support. We say yes to a new local high school. Northeast Secondary Education Committee." The photographer comments, "A bike ride to New Brighton and the beach 3 weeks after the Feb 22 quake. Roads were still very rough and under reconstruction. I think this issue may be shelved for a while. Unless Shirley Boys High and Avonside Girls High can't be rebuilt, of course".

A sign above the 3 Wise Men shop in the Re:Start mall, reading "Re:Start, supported by ASB". The photographer comments, "The new temporary city mall has been open in Christchurch now for a week. Buildings damaged in the earthquake have been demolished and replaced with cargo containers to create a new, temporary, Cashel Mall. I visited the mall yesterday and was quite impressed with what they have done. The cargo containers have been nicely converted, brightly painted and smartly branded to create some good looking stores".
