AS 5146.2:2018 PDF Download

The AS 5146.2:2018 standard provides requirements and methods for determining the characteristic properties of Reinforced Autoclaved Aerated Concrete (AAC) members. This standard applies to members with a minimum thickness of 50 mm and is intended for use in structures that comply with AS 5146.1.

Reinforced AAC refers to walls, floor or roof panels, or other members made of AAC in which steel reinforcement has been cast. These members can be used for various purposes, such as loadbearing and non-loadbearing wall panels, fascias, cladding, roofs, floors, beams, lintels, piers, noise barriers, and earth retaining structures.

Notably, the standard does not cover the design or use of unreinforced AAC blocks or the use of Reinforced AAC subjected to dynamic loads, except for earthquake loads. It also does not address finishes, fixings, supporting structures, or the design of members using alternative materials or methods. The execution of work under this standard should be carried out by appropriately qualified individuals experienced in Reinforced AAC construction.

The standard emphasizes the importance of experienced structural engineers in performing the design and determining design actions, material properties, section properties, bending moments, shears, and deflections according to the provisions of this standard. It also provides means for demonstrating conformance with the standard, which are detailed in Appendix AA.
