During the Christchurch earthquake of February 2011, several midrise buildings of Reinforced Concrete Masonry (RCM) construction achieved performance levels in the range of life safety to near collapse levels. These buildings were subjected to seismic demands higher than the building code requirements of the time and higher than the current New Zealand Loadings Standard (NZS-1170.5:2004). Structural damage to these buildings has been documented and is currently being studied to establish lessons to be learned from their performance and how to incorporate these lessons into future RCM design and construction practices. This paper presents a case study of a six story RCM building deemed to have reached the near collapse performance level. The RCM walls on the 2nd floor failed due to toe crushing reducing the building’s lateral resistance in the east-west direction. A nonlinear dynamic analysis on a 3D model was conducted to simulate the development of the governing failure mechanism. Preliminary analysis results show that the damaged walls were initially under large compression forces from gravity loads which caused increase in their lateral strength and reduced their ductility. After toe crushing failure developed, axial instability of the model was prevented by a redistribution of gravity loads.

A digital copy of a painting by Julia Holden. The painting is of Lichfield Street, looking east from the intersection of Colombo Street. The road has been fenced off and there are damaged buildings in the background.
Tents set up in the Arts car park at the University of Canterbury after the 22 February 2011 earthquake. The tents were used as temporary lecture rooms while the buildings were being checked for damage.
A view of Colombo Street, looking north from Kilmore Street. Many of the buildings on the left side have been demolished, and on the right they are badly damaged. Piles of gravel have been heaped on the side of the road.

Structural damage to St Elmo Courts with diagonal cracks between the windows of the building. These cracks show that there has been rocking of the masonry piers which means there is no vertical reinforcement provided in the walls.
The Oxford Terrace Baptist Church with cracks on the front facade. Bracing has been placed under the roof and at the front of the church to support the building and limit further damage from aftershocks.

A photograph of an earthquake damaged building on Armagh Street with a tarpaulin draped over the roof. In the distance, a pile of bricks have been laid on the road in front of the Cranmer Centre.
A photograph of the earthquake damage to the Cranmer Centre on the corner of Montreal and Armagh Streets. The front wall of the building has crumbled, and the bricks have spilt onto the pavement below.
A photograph looking south-west along Williams Street, from the Williams Street bridge, in Kaiapoi. In the distance is the rebuilt Blackwell's Department Store. The department store was rebuilt after the previous building was damaged in the 2010 and 2011 Canterbury earthquakes.

A photograph of the Durham Street Methodist Church blocked off by wire fencing. The top right corner of the building is damaged and some of the masonry has fallen onto to the footpath below.
Winnie Bagoes on Gloucester Street. The top storey of the building has collapsed, bringing the roof down with it. Bricks and rubble lie in a pile on Gloucester Street where they fell.
The badly-damaged Knox Presbyterian Church on the corner of Bealey Avenue and Victoria Street. The brickwork in the gables has crumbled, exposing the wooden structure underneath. Spray-painted USAR codes can be seen on the brick wall.
Forbes' Store on Norwich Quay with a broken awning and damage visible on the brick walls. Scaffolding placed around the building since the 4 September 2010 earthquake has tumbled during the 22 February 2011 earthquake.
