A proposed design by John Raven for a new cathedral, tied to a cordon fence. Clarendon Tower can be seen in the background. The photographer comments, "Someone is asking for designs for a new Christchurch Cathedral after it was announced that the old historical building will not be repaired, to be put on the fences through which people can see the de-construction of the old one. This design looks a great one to me".

Describes an extensive experimental program at the University of Canterbury, for the development of new structural systems and connections for multi-storey laminated veneer lumber (LVL) timber buildings in earthquake-prone areas. The proposed innovative ductile timber connections are conceptually similar to recent seismic solutions successfully developed for precast concrete multi- storey buildings. The paper gives an overview of the research program, and the results of quasi-static cyclic tests on frame subassemblies, including exterior beam-column joints and cantilever columns, as well as pseudo-dynamic tests on cantilever columns. The experimental results showed significant dissipation of hysteretic energy, good self-centering capacity and no appreciable damage of the structural elements, confirming the expected enhanced performance of the proposed structural systems.

A digitally manipulated photograph of broken windows on Shadbolt House. The photographer comments, "This was close to the start of the demolition of the earthquake damaged Shadbolt House building in the Port of Lyttelton, New Zealand. In the bright sun the glass reflected the blue sky, but the broken windows only reflected the blackness of the interior of the empty broken building".

The Canterbury Earthquake Sequence (CES), induced extensive damage in residential buildings and led to over NZ$40 billion in total economic losses. Due to the unique insurance setting in New Zealand, up to 80% of the financial losses were insured. Over the CES, the Earthquake Commission (EQC) received more than 412,000 insurance claims for residential buildings. The 4 September 2010 earthquake is the event for which most of the claims have been lodged with more than 138,000 residential claims for this event only. This research project uses EQC claim database to develop a seismic loss prediction model for residential buildings in Christchurch. It uses machine learning to create a procedure capable of highlighting critical features that affected the most buildings loss. A future study of those features enables the generation of insights that can be used by various stakeholders, for example, to better understand the influence of a structural system on the building loss or to select appropriate risk mitigation measures. Previous to the training of the machine learning model, the claim dataset was supplemented with additional data sourced from private and open access databases giving complementary information related to the building characteristics, seismic demand, liquefaction occurrence and soil conditions. This poster presents results of a machine learning model trained on a merged dataset using residential claims from the 4 September 2010.

A crane topples over on Victoria Street while taking glass up to some windows. No one was hurt and the glass never broke. Victoria Street was closed from 7:30am to later in the evening. This all happen on the Knox Plaza building site. Christchurch October 13, 2014 New Zealand.

One landscape colour digital photograph taken on 6 September 2010 showing earthquake damage to buildings on Victoria Street near Bealey Avenue. The red brick building is the Knox Church; it still stands on the corner of Bealey Avenue and Victoria Street following the earthquake, though some extreme measures were taken to make it safe. The red b...
