Unreinforced masonry (URM) cavity-wall construction is a form of masonry where two leaves of clay brick masonry are separated by a continuous air cavity and are interconnected using some form of tie system. A brief historical introduction is followed by details of a survey undertaken to determine the prevalence of URM cavity-wall buildings in New Zealand. Following the 2010/2011 Canterbury earthquakes it was observed that URM cavity-walls generally suffered irreparable damage due to a lack of effective wall restraint and deficient cavity-tie connections, combined with weak mortar strength. It was found that the original cavity-ties were typically corroded due to moisture ingress, resulting in decreased lateral loadbearing capacity of the cavity-walls. Using photographic data pertaining to Christchurch URM buildings that were obtained during post-earthquake reconnaissance, 252 cavity-walls were identified and utilised to study typical construction details and seismic performance. The majority (72%, 182) of the observed damage to URM cavity-wall construction was a result of out-of-plane type wall failures. Three types of out-of-plane wall failure were recognised: (1) overturning response, (2) one-way bending, and (3) two-way bending. In-plane damage was less widely observed (28%) and commonly included diagonal shear cracking through mortar bed joints or bricks. The collected data was used to develop an overview of the most commonly-encountered construction details and to identify typical deficiencies in earthquake response that can be addressed via the selection and implementation of appropriate mitigation interventions. http://www.journals.elsevier.com/structures
A photograph of the earthquake damage to the Base Packpackers building behind the former Canterbury Times building on Gloucester Street. The corner of Base Backpackers has collapsed, exposing a bunkroom inside. Scaffolding has been constructed up the side of the building.

A photograph of the earthquake damage to a stairwell in the Crowne Plaza Hotel on the corner of Kilmore and Durham Streets. Large sections of the concrete wall behind the stair rail have broken away to reveal the steel reinforcement underneath.
A photograph of the earthquake damage to Kudos Hairdressers on the corner of Papanui Road and Mansfield Avenue. The façade of the building has crumbled, the bricks falling to the footpath. Police tape has been draped around the building as a cordon.
A photograph of the earthquake damage to the Loyal Benevolent Lodge on Canon Street. Bricks at the top of the façade have crumbled and fallen to the ground, bringing the awning with them. Large cracks can be seen in the remaining brick wall.
A photograph of the earthquake damage to the Asko Design building on Victoria Street. The front facade and side wall have crumpled, exposing the inside of the buildings. The awnings over the windows have been twisted and ripped off by the falling bricks.
A photograph looking north up Colombo Street across the intersection of Kilmore Street. The buildings on either side of the street have been severely damaged by the earthquakes. The rubble and other debris has since been cleared from the street and footpaths.
A photograph of the second storey of the partially-demolished Westende Jewellers Building on the corner of Manchester and Worcester Streets, which housed Alva Rados Mexican restaurant. The building was severely damage during the 4 September 2010 earthquake and had to be demolished.
Earthquake damage down New Brighton Road. There is cracking on the footpath and cars are parked on the front lawns as silt from liquefaction still remains on the street curb. A van with a 'school' sign can be seen driving down the road.
A photograph of the earthquake damage to a Stonehurst Accommodation building on Gloucester. The bottom storey of the building has collapsed and the top two storeys are resting on the rubble. One wall of the building has also collapsed, exposing the rooms inside.
A photograph of the earthquake damage to a house on Woodham Road. The house has come off its foundations as the bricks wall have crumbled, spilling onto the footpath in front. Road cones have been placed along the street to warn road users.
A photograph of the earthquake damage to a house. Large cracks have formed in between the bricks in the wall of the house. There is also a large crack on the left side of the second storey where the column has shifted.
A photograph of the earthquake damage to the Domo furniture store on Tuam Street. A large section of the building has collapsed and the rubble has spilled onto the street below. Wire fencing has been placed around the building as a cordon.
A photograph of the earthquake damage to a concrete beam inside a building. The wall around the beam has been removed to access the beam. Concrete near the bottom of the beam has crumbled and the steel reinforcement inside is now exposed.

A yellow sticker on the door of a house in Worcester Street reading, "Restricted use. No entry except on essential business. Warning: This building has been damaged and its structural safety is questionable. Earthquake aftershocks present danger. Enter only at own risk. Subsequent events may result in increased damage and danger, changing this assessment. Reinspection may be required. The damage is as described below: partial collapse of longitudinal walls". Following on from this are the specific conditions that must be complied with to enable entry into the property, the inspector's identification details, and the date and time the building was inspected. At the bottom the form reads, "Do not remove this placard. Placed by order of the territorial authority Christchurch City Council".
The earthquake re-pair work has started on the Knox Church on Bealey Avenue, August 14, 2013 Christchurch New Zealand. While building after building is torn down in Christchurch, plans are in place to ensure as much of a 131-year-old church is retained as possible. Knox Church on Bealey Avenue suffered major damage in the February 22 earthquak...
Damage to buildings along Norwich Quay in Lyttelton. To the left is the Lyttelton Hotel with a crumbled top. Bricks have fallen on the awning and all along the footpath. To the right is a cafe that was damaged severely in the earthquake. The front wall of the top storey has crumbled onto the street, crushing a car. Wire fencing and road cones have been used to create a cordon around the buildings.
The damaged Cranmer Courts on the corner of Kilmore and Montreal Streets. The corner of the building has crumbled onto the street, which is now littered with broken masonry. Wire fencing placed around the building after the 4 September 2010 earthquake has managed to keep the debris away from the road.
A photograph of a fence on the Greendale Fault line which has been damaged by the 4 September 2010 earthquake. The wire has been pulled off the posts and is hanging loose. The ground has also shifted so the fence is no longer straight.
