Abstract:
Australian Standard AS 3610-1990 was the first national Standard to introduce limit states formwork design method; however, until all material Standards converted to limit states design, permissible stress design rules remained part of the Standard. At the time, the new limit states design rules were controversial. Even now, when limit states Standards are available for all formwork materials, few designers have opted to use limit states design methods. To some extent, this inertia has been vindicated by the results of recent research that casts doubt on the reliability of the limit states design rules in AS 3610. Thus it is not without some controversy that Standards Australia publishes AS 3610.0:2003 Formwork for concrete, which omits permissible stress methods and introduces new limit states design rules. This paper reviews the new design rules, highlighting and providing the background to the changes.
