Aluminium alloys are increasingly used in the construction industry, as they offer high strength-to-weight ratios,good durability and ease of fabrication. An aluminium helideck structure should satisfy the requirements of offshoreregulations and rule notations such as the Australian/New Zealand Standard and EUROCODE 9, in which the width-tothickness ratio and yield stress are the recognised governing parameters for the design of cross-sections. Aluminiumhelideck structures are composed of several structural units, which can be aluminium or steel. The aluminium partsare the pancake, girder, safety net, etc. In this study, the aluminium helideck design with the relevant EUROCODE 9is based on the strength calculation. It may be possible to reduce the calculation time and thus provide a reasonablesolution in terms of a practical design. The static and nonlinear collapse behaviour of a developed structure isinvestigated in this study. The primary aim is to provide a reasonable solution that can improve product quality bychecking both strength and deformation criteria. The effect of de?ection during the fabrication stage is considered inthe structural design based on the newly proposed EUROCODE 9. Lastly, a comparison between the results of thisstudy and those from fnite element analysis is presented.
