Matthew McEachen should have had most of his life ahead of him when he died on February 22, 2011.
The 25-year-old was a talented artist and designer, putting his skills to good use at the Southern Ink tattoo shop on Colombo St.
But when the earthquake struck, Bruce, Jeanette and Sarah McEachen lost their much-loved son and older brother.
Ten years on, Matti's legacy lives on. Checkpoint reporter Nick Truebridge and cameraman Nate McKinnon with his story.
Glazing systems are non-structural elements in a building that, more often than not, appear to be given little consideration in seismic design. Recent experimental work into glazing systems at the University of Canterbury, however, has shown that glazing systems can be very susceptible to serviceability damage, defined as loss of water-tightness. The focus of this paper is to highlight the difference in vulnerability of standard and seismic glazing systems and consider the implications of this for future repair costs and losses. The paper first describes the damage states chosen for glazing units according to the repair strategies required and expected repair costs. This includes three damage states: DS1: Water Leakage, DS2: Gasket Failure and DS3: Frame/Glass Failure. Implementing modern performance-based earthquake engineering, the paper proceeds to highlight a case study comparing costs and expected losses of a standard glazing unit and a seismic glazing unit installed on a case study building. It is shown that the use of seismic glazing units is generally beneficial over time, due to the early onset of serviceability damage in standard glazing units. Finally, the paper provides suggestions for designers aimed at reducing costs related to earthquake induced repairs of glazing.
