Evaluation of Current Standards in Designing Cold-rolled Aluminium Channel Beams

Abstract

Cold-rolled aluminium alloy sections have been well known as new products of BlueScope Permalite, and have been produced by utilising the existing rolling system for cold-formed steel sections to successfully roll-form Channel and Zed sections in Australian market. The roll-forming approach is proven to be faster and more cost-effective as compared to the conventional extrusion method. This method has attracted the attention from the manufacturers and users as well as researchers which resulted in the ARC Linkage Research Project-LP140100863 grant funded by the Australian Research Council and BlueScope Permalite to perform research on these types of cold-rolled aluminium sections. One of the objects in this project is to evaluate the application of current design standards in designing cold-rolled aluminium alloy members which are necessary to propose modifications in Aluminium design standards. This paper presents the applicability of current Aluminium design standards including Australian Standard, American Specification and Euro code in designing cold-rolled Aluminium Alloy Channel Beams by using reliability analysis.
