Description
Guidance on barrier design replaced the Acceptable Solution for timber barriers, B1/AS2, which was discontinued on 31 January 2012.
Scope
Guidance on barrier design addresses a range of areas including barrier geometry, loadings, deflection limits, and testing procedures to prove a design’s performance. It also provides information for barriers constructed of timber, glass and metals, and includes a useful checklist for building consent application checking at the end of the document.
The barrier guidance incorporates loadings from AS/NZS 1170, Structural Design Actions, and covers the range of materials now being used. Most barriers currently being built are of materials other than timber, such as glass and metal.
