A year after the first earthquake on 4 September 2010, aftershocks continue to be felt in Canterbury, and they're not always seismic ones. When buildings collapse or are cordoned off, or even just closed for repairs - what happens to the lives and livelihoods of those who used to fill them with noise and energy? Kris Vavasour returns to Lyttelton to catch up with performers and friends, to hear about life in an altered landscape.

A photograph of participants in the walk to celebrate Chinese National Day and the Moon Festival. In the foreground, there are two performers doing a lion dance. The walk was held at the Upper Riccarton Library in September 2015. It was organised by the Canterbury Migrants Centre (formerly the Christchurch Migrants Centre) and was part of the Christchurch City Council's Walking Festival.

An audio documentary created by Kris Vavasour about the multitude of challenge the musicians, performers and venue owners in Lyttelton face in the aftermath of the Canterbury earthquakes. All songs are from the 'Harbour Union' album (2011), in alphabetical order: 'Even Keel' (Lindon Puffin); 'Ghost of this Town' (Marlon Williams); 'How Lucky You Are' (Delaney Davidson & Marlon Williams); 'Human Enough' (Lindon Puffin); 'It's So Good' (Delaney Davidson); 'Little Mountain Town' (Marlon Williams); 'Rocking Bell' (Adam McGrath); 'The Waterside' (Adam McGrath).

A poster advertising performers Maryrose Crook, Purple Pilgrims and Thje. The photographer comments, "Maryrose Crook, Purple Pilgrims, Thje. Saturday 26 Feb (2011). HSP 9PM $5. HSP stands for High Street Project. Here is the introduction for her concert 'Maryrose Crook's spectral voice and calenture tunes float through New Zealand giants, The Renderers' psychic country-punk and splatter rock, and emerge in her solo encounters with horripilated grace and filigree menace. Purple pilgrims' wraithish hymns evolve through a braided field of curled nautical drone and distant littoral roar, abstract thrums and change-rung celestial rustle'. She was supposed to perform on 26 February, but I am guessing the concert was cancelled due to the major earthquake in Christchurch on the 22nd. The horrendous quake made the venue at 84 Lichfield Street out of limits due to it being in the dangerous earthquake red zone. It looks like she next performed on the 17 May at the Loons in Lyttelton".

This thesis aims to find a new weld sizing criterion for the steel construction industry in New Zealand. Current standards, such as NZS 3404, ANSI/AISC 360-16, and Eurocode 3 use a factor of 0.6 to calculate weld capacity from the weld metal’s ultimate tensile strength (UTS). This difference between weld capacity and UTS is thought to have arisen from the need for a large factor of safety to ensure welds perform correctly during an earthquake. The events in Christchurch proved that this criterion was able to work as intended. Several papers have been published by P. Dong from University of Michigan, and alongside other researchers, they investigate a new definition of weld shear strength by using a traction stress-based method. This new method not only allows realistic angles of weld fracture to be investigated, but also different weld geometries such as partial penetration butt welds. Ongoing research at HERA is showing how this welding technique is a more economical option than larger fillet welds with similar performance. For this thesis a range of sample types were statically tested until failure. UTS of several weld metals was found and then compared with transverse shear results to see if 0.6 is indeed correct. It was found that if the results from the standardized transverse shear samples was used, this ratio could be increased to 1.0. But if the results from cruciform joint samples was used, which still load the weld in a transverse direction but with a higher stress concentration, required the ratio to be 0.8 for welds that could be welded with a single pass, and decreased further to 0.75 for large welds with 3 passes. Two types of partial penetration butt weld (PPBW) geometries were compared to a comparatively sized fillet weld. These tests showed the PPBWs were the best performers, with all PPBWs surviving testing compared to only 33% of fillet welds.
