A revised Commentary document complementing the Australian Standard AS 3600, Concrete Structures Standard provides additional industry guidance on the design and construction of concrete structures.
The commentary document, AS 3600:2018 Sup 1:2022, is a resource that industry can use in conjunction with the Concrete Structures Standard. It provides explanation and interpretation, gives background and guidance, highlights changes in previous practices, and provides references and further readings.
The Commentary aims to help users of the Concrete Structures Standard understand and interpret design and classification requirements. Significantly, it includes guidance on what can be often misunderstood requirements for the design of concrete structures to resist earthquakes, particularly, the use of force-based design procedures and the rationale behind detailing rules, which are intended to ensure ductility of streel reinforcements.
The document also aims to give guidance on classifications that assist industry in determining what level of ‘resilience’ buildings need according to their intended use. For example, authorities may dictate that critical structures such as hospitals, emergency services or similar buildings should be better protected.
”It is vital these buildings have a higher level of resilience so that Australia’s government and crucial services can continue to operate.

BD-002, the Concrete Structure committie, was prompted to revise the earthquake requirements of the Standard and Commentary document following the most recent earthquake in Christchurch, New Zealand.
Earthquakes aren’t commonplace in Australia, and are therefore sometimes misunderstood. But the risk remains that one could occur tomorrow or in 100 years, thus it is important to be as prepared as possible for when it does happen.
Additionally, the document has been updated on steel fibre reinforcement, providing further explanation. It also provides guidance on a new approach to shear, a common part of structural analysis, with the aim of ensuring the industry is keeping up to date with current technology.
Standards Australia is supporting industry with this Commentary in order to help users interpret and implement AS 3600.
Standards have a significant role to play in improving safety in the construction and design sector, as the changing dynamics and risks of earthquakes continue on into the future.
