Film and TV reviewer Tamar Munch takes a look at the new US drama The Outsider, based on the Stephen King novel of the same name, and Help Is On The Way, a Kiwi documentary based on the 6.3 Christchurch earthquake and what happened to the 36 guest trapped on the top floors of the Hotel Grand Chancellor.

A photograph taken from the top of the BNZ building. The photograph is captioned by BeckerFraserPhotos, "Finally, the mess outside Coffee Culture on High Street has been cleared and demolition work will complete what the earthquake began. The red containers in the background are Fletchers containers, servicing the Hotel Grand Chancellor deconstruction".

On 22 February 2011, Christchurch police sargeant Dave Harvey was outside the earthquake-damaged Hotel Grand Chancellor on Cashel Street, unsure if anyone was trapped inside. In case they were, he grabbed a can of spray paint and painted 'Help is on the way' in one-metre high letters on the road. Harvey's quick thinking really helped the people trapped in the hotel, says Clare Mackey, producer of the new documentary Help is on the Way.

An aerial photograph of the Christchurch central city. The photograph has been captioned by BeckerFraserPhotos, "High Street runs across this photograph in the top third from the old Majestic Theatre at the intersection of Manchester and Lichfield Streets to the intersection of Madras and St Asaph Street which is just beyond the edge of the photo".

Following the recent earthquakes in Chile (2010) and New Zealand (2010/2011), peculiar failure modes were observed in Reinforced Concrete (RC) walls. These observations have raised a global concern on the contribution of bi-directional loading to these failure mechanisms. One of the failure modes that could potentially result from bidirectional excitations is out-of-plane shear failure. In this paper an overview of the recent experimental and numerical findings regarding out-of-plane shear failure in RC walls are presented. The numerical study presents the Finite Element (FE) simulation of wall D5-6 from the Grand Chancellor Hotel that failed in shear in the out-of-plane direction in the February 2011 Christchurch earthquake. The main objective of the numerical study was to investigate the reasons for this failure mode. The experimental campaign includes the recent experiments conducted in the Structural Engineering Laboratory of the University of Canterbury. The experimental study included three rectangular slender RC walls designed based on NZS3101: 2006-A3 (2017) for three different ductility levels, namely: nominally ductile, limited ductile and ductile. The numerical results showed that high axial load combined with bi-directional loading caused the out-of-plane shear failure in wall D5-6 from the Grand Chancellor Hotel. This was also confirmed and further investigated in the experimental phase of the study.

An aerial photograph of the Copthorne Hotel on Colombo Street. The photograph has been captioned by BeckerFraserPhotos, "When the PricewaterhouseCoopers building is demolished, the Copthorne Central Hotel will be alone on the block. Oxford on the Avon and Plunket House are also gone from Oxford Terrace, and on the other side of the river is the demolition site of the PGC building where 18 people died".

Photographs of central Christchurch after the 2010-2012 earthquakes taken 25 February 2012 by Sean McMahon. Locations are chiefly Manchester, Saint Asaph, Cashel, Columbo and Lichfield Streets, and the Bridge of Remembrance. Images show fencing around areas closed to the public, damaged and collapsed commercial buildings, cleared sites, re-opened Cashel Street area with shops and a cafe.

An aerial photograph of the Christchurch central city. The photograph has been captioned by BeckerFraserPhotos, "This photograph shows nearly all of the CBD. The two streets which are prominent in this photograph are Manchester Street on the left and Colombo Street on the right of the photograph. This photograph is from the north, looking towards the southern part of the city. Cathedral Square is about half way up, towards the right. It shows the extent of demolition that has happened already close to the river and near the Manchester/Gloucester Street intersection where there is a lot of bare land surrounding Radio Network House".

An aerial photograph captioned by BeckerFraserPhotos, "Victoria Square is at the centre of this picture with its green lawns and trees. The bare patch of earth in front s the demolition sites of the Allan McLean building, the Oxford on Avon, and Plunket House. The contract to demolish the Crowne Plaza Hotel has been let, while the fate of the Town Hall is still undecided. The Convention Centre is coming down. On the very bottom, slightly to the right is the Medlab building which is also to be demolished. In the bottom left corner is the PWC building which is also to be demolished".

One of the failure modes that got the attention of researchers in the 2011 February New Zealand earthquake was the collapse of a key supporting structural wall of Grand Chancellor Hotel in Christchurch which failed in a brittle manner. However, until now this failure mode has been still a bit of a mystery for the researchers in the field of structural engineering. Moreover, there is no method to identify, assess and design the walls prone to such failure mode. Following the recent break through regarding the mechanism of this failure mode based on experimental observations (out-of-plane shear failure), a numerical model that can capture this failure was developed using the FE software DIANA. A comprehensive numerical parametric study was conducted to identify the key parameters contributing to the development of out-of-plane shear failure in reinforced concrete (RC) walls. Based on the earthquake observations, experimental and numerical studies conducted by the authors of this paper, an analytical method to identify walls prone to out-of-plane shear failure that can be used in practice by engineers is proposed. The method is developed based on the key parameters affecting the seismic performance of RC walls prone to out-of-plane shear failure and can be used for both design and assessment purposes
