The Insight: Redundant Non-Structural Systems within AS5216:2021
17 November 2021Design of redundant non-structural systems
Redundant non-structural systems (RNSS) apply to post-installed fasteners connecting statically indeterminate non-structural light weight systems in cracked and un-cracked concrete base material. Simply put this type of design typically applies to applications like suspended ceiling systems, pipe support systems and other types of MEP (Mechanical, Electrical and Plumbing) applications with multiple fixing points. Testing and assessment of post-installed fasteners that comply with RNSS design for safety critical applications is covered under Appendix E of AS 5216:2021.In Europe fasteners which have been tested and comply for use in RNSS hold an ETA in accordance with EAD 330747-00-0601 (Fasteners for use in concrete for multiple use for non-structural systems).
