C6 Structural stability

Structural stability during fire: buildings remain stable during fire (likelihood of failure or collapse).

This clause takes into account factors affecting the fire severity and its impact on structural stability. It requires structural systems to provide firefighters with safe access to floors, during and after fire. It protects from the collapse of building elements with lesser fire resistance, so they do not consequentially cause the collapse of elements of a higher fire resistance.

C1 provides objectives for each of the C clauses.

Most of the guidance applies to all of the C clauses and some relates to a specific clause.

There may be specific products and determinations under each code clause.

The 2019 1st edition of C/AS2 combining C/AS2–C/AS7 is summarised in this fact sheet.

Updates

Acceptable Solutions and Verification Methods

Current version

These are issued by MBIE to provide one way of complying with the Building Code and must be accepted by BCAs as demonstrating compliance with the related clauses of the Building Code. Using them is not mandatory.

 

Acceptable Solutions and Verification Methods (AS and VMs) were called compliance documents. Some still have the “compliance document” title but the AS or VMs they contain are valid and unaffected by the name change.

Standards

Standards are frequently referred to in Acceptable Solutions and Verification Methods. They provide practical information and guidelines for building solutions.

Over 120 building standards used for Building Code compliance are now available for free download.

See the free standards relating to Code Clause C6.

All standards, including the funded ones, can be accessed through the Standards New Zealand website.

Guidance

These documents are provided to assist Building Consent Authorities, building owners, designers and persons who carry out building work.

Related Determinations
