scope:

SNZ HB 3604:2011 Timber-framed buildings - Selected extracts from NZS 3604:2011 (SNZ B 604) rovides users with a collection of figures and tables extracted from NZS 3604 and directs them to the appropriate section of the Standard for full information.

SNZ HB 3604 is not a design guide. When designing buildings to comply with NZS 3604:2011 reference should be made only to the full version of the Standard.

Inclusions

Light timber-framed buildings designed using NZS 3604 are within the parameters of NZS 3604, 1.1.1 and 1.1.2, table 1.1 (a) nd gure .1.

NZS 3604 figure 1.2 is a summary of buildings covered by NZS 3604.

Interpretation

References in sections, figures and tables to sections/clauses are to named sections/clauses in NZS 3604. Defined terms are in italic except in the foreword, headings, tables, figures and notes.

Exclusions

Buildings not covered in this handbook are outlined in NZS 3604 table 1.1(b). Additionally this handbook does not cover floor loads over 2.0 kPa, snow loading over 1.5 kPa and composite construction lintels.

Tables giving sizes of timber members are confined to Structural Grade SG 8 for both wet and dry timber. For corresponding SG 6 and SG 10 tables see the appendices in relevant sections of NZS 3604.

Buildings not covered by NZS 3604 shall be specifically designed by a structural engineer. In cases where the building complies with the Standard except for minimal instances such as the length of a lintel, specific design may be applied to that element only (from NZS 3604, 2.2.3 and 1.1.4).
