A video of a tour through the Christchurch central city Red Zone. The video includes footage of Armagh Street, Madras Street, Latimer Square, St John's Anglican Church, Hereford Street, the Octagon Live restaurant, the Design and Arts building, the High Street mall, and the Grand Chancellor Hotel. It also includes footage of construction workers cutting up metal beams, and clearing rubble from a building on Manchester Street.

Shaking table testing of a full-scale three storey resilient and reparable complete composite steel framed building system is being conducted. The building incorporates a number of interchangeable seismic resisting systems of New Zealand and Chinese origin. The building has a steel frame and cold formed steel-concrete composite deck. Energy is dissipated by means of friction connections. These connections are arranged in a number of structural configurations. Typical building nonskeletal elements (NSEs) are also included. Testing is performed on the Jiading Campus shaking table at Tongji University, Shanghai, China. This RObust BUilding SysTem (ROBUST) project is a collaborative China-New Zealand project sponsored by the International Joint Research Laboratory of Earthquake Engineering (ILEE), Tongji University, and a number of agencies and universities within New Zealand including BRANZ, Comflor, Earthquake Commission, HERA, QuakeCoRE, QuakeCentre, University of Auckland, and the University of Canterbury. This paper provides a general overview of the project describing a number of issues encountered in the planning of this programme including issues related to international collaboration, the test plan, and technical issues.

About two hundred of those who lost loved ones in collapsed buildings in Christchurch's 2011 earthquake, heard an apology from the city's mayor, Lianne Dalziel yesterday. A royal commission in to faulty buildings found serious errors by engineers and the Christchurch City Council 185 people died during the earthquake on the 22nd of February, 2011. David Selway who lost his sister Susan Selway in the CTV Building, said it was good to hear a heartfelt apology from the mayor for the role her council played in signing off the building as safe.

Base isolation is arguably the most reliable method for providing enhanced protection of buildings against earthquake-induced actions, by virtue of a physical separation between the structure and the ground through elements/devices with controlled force capacity, significant lateral deformation capacity and (often) enhanced energy dissipation. Such a design solution has shown its effectiveness in protecting both structural and non-structural components, hence preserving their functionality even in the aftermath of a major seismic event. Despite lead rubber bearings being invented in New Zealand almost forty years ago, the Christchurch Women's hospital was the only isolated building in Christchurch when the Canterbury earthquake sequence struck in 2010/11. Furthermore, a reference code for designing base-isolated buildings in New Zealand is still missing. The absence of a design standard or at least of a consensus on design guidelines is a potential source for a lack of uniformity in terms of performance criteria and compliance design approaches. It may also limit more widespread use of the technology in New Zealand. The present paper provides an overview of the major international codes (American, Japanese and European) for the design of base-isolated buildings. The design performance requirements, the analysis procedures, the design review process and approval/quality control of devices outlined in each code are discussed and their respective pros and cons are compared through a design application on a benchmark building in New Zealand. The results gathered from this comparison are intended to set the basis for the development of guidelines specific for the New Zealand environment.

The brick facade has fallen from the former Princess Cinema in New Brighton, exposing the rooms inside, and crushing a car parked below. The photographer comments, "The front of the old Princess Cinema in New Brighton after the earthquake in Christchurch, New Zealand on 22 February. Under the pile of bricks is a luckily unoccupied blue car. The word CLEAR on the broken facade is to show that there is no one in the car. This building has now been knocked down as it was so dangerous".
