“When it comes to the structural design of a deck, the Australian Standards AS1170.1-2011 (Structural design Actions – Permanent, imposed and other actions), clearly sets out the required live load (traffic load) required for each application. In the case of the deck at Oxygen Apartments, this called for a design live load of 4.0 kPa (approximately 400 kg/m2). With such as heavy live load, the deck structure needed to be robust enough to pull the dynamic deflection (bounce) out of the structure under this loading.
This was achieved via the use of pre-welded aluminium bearer/column frames. The main advantage of using aluminium in external salinic environments such as coastal areas and around pools, is that its corrosion rate is much slower then compared to the rapid corrosion rate of steel (assuming the PH of the pool water is controlled). Aluminium also has the advantage over that of a conventional timber framed deck, in that it is not subject to timber rot as a result of constant wetting and drying.
The use of Rubicab’s Eco Composite Wood decking, which will not rot, and is termite and pest resistant, in addition to the aluminium structural frames, results in a deck that is virtually maintenance free, and will outlive that of conventional steel and timber decks.”
