Central Queenslanders aren’t strangers to natural disasters, and while cyclones are more prevalent than earthquakes, having sturdy structures in place is still paramount and can provide peace of mind.
In this blog, we look at which of Bris Aluminium’s partition systems are most suitable for key locations across Central Queensland, based on their hazard factor.
But first, what are the Australian standards for seismic movements?
Australian Standards for Seismic Movements
Bris Aluminium has had our entire range of aluminium internal partition systems independently assessed in relation to AS 1170.4 – 2007 “Structural design actions Part 4: Earthquake actions in Australia”. You can download a copy of the report from our website here.
This standard sets out data and procedures for determining earthquake loads on structures and their components, and also minimum detailing requirements for structures, including Hazard Factor (Z) for specific Australian locations, including towns and cities in Central Queensland.
Additionally, AS 1170.0-2002 is also referenced in the independent report, which relates to “Structural Design Actions – General principles.”
Does My Fit Out Need to Comply with Seismic Design Requirements?
First and foremost, we’d recommend discussing your local requirements with your designer, engineer or builder.
It’s important to note that if you specify and use Bris Aluminium internal partitioning products in your fit out, you can be confident that they have been independently assessed and meet the Australian seismic standards.
While the risk of an earthquake is still relatively low for Central Queensland, it is slightly higher than South-East Queensland or North Queensland (Townsville, Cairns).
We do recommend checking the specific Hazard Factor for the location of your project and reviewing which Bris Aluminium system may be more suitable for your needs (which are covered below).
Earthquake Hazard Factors for Central Queensland
The below list shows the AS1170.4 hazard factors set out in a report by the Australian Earthquake Engineering Society.
- Bundaberg has a hazard factor of 0.11
- Gladstone has a hazard factor of 0.09
- Rockhampton has hazard factor of 0.08
- Mackay has a hazard factor of 0.07
Aluminium Partitions for Regional Queensland
With the above figures in mind, we wanted to outline which of Bris Aluminium’s quality-assured ISO-9001 certified partition systems will be suitable for your regional city.
All of our aluminium framing systems – with the exception of the Supreme 64 Slimline System – are adequate for buildings with an importance level of 4 and a maximum hazard factor of 0.08.
So that means the following systems can be used in those structures in Rockhampton and Mackay:
- Supreme 92 System
- Supreme 76 System
- Supreme 64 System
- Econo 76 system
- Econo 64 system,
- Adjustable System
- Cavity slider System
- Light duty shopfront System
Only two of our systems are adequate for importance level 4 structures in localities with a maximum hazard factor of 0.22 – the Supreme 76 and Supreme 92.
That means, if you intend to go through the formal seismic approval process, these two framing solutions are the only partition systems suitable for homes and businesses in Bundaberg and Gladstone.
You can access the independent report for Bris Aluminium products here. In this report, all Bris Aluminium framings have been reviewed under an SLS1 Seismic event only.
