Applies to design and construction of prestressed concrete structures, including composite structures comprising prestressed concrete members and plain and reinforced concrete members. It excludes concrete pipes. It covers a wide spectrum of structures including prestressed concrete with untensioned reinforcement, post-tensioned flat slabs and liquid-retaining structures, and includes rational methods of design which provide for estimation of losses of prestress taking into account the properties of Australian materials. It also covers ground anchorages which have been successfully used in Australia under a wide variety of conditions.
