Calls to the BRANZ Helpline indicate that there is still confusion about the correct use of bottom plate anchors with concrete floor slabs.
An online calculator has replaced the paper version of the BRANZ Guide to lintels and beams.
Securing roofs against wind uplift is a crucial step in the building process. Fortunately the cost of doing so adds very little to the overall cost of the building.
NZS 3604 provides design parameters for deck design for 2.0 kPa floor loadings. However, the designer must consider the load that a deck or balcony may potentially carry and, if it is likely to exceed this loading, the design parameters should be increased accordingly.
Roof bracing is one element in a continuum that provides resistance to horizontal loads. It works with the wall and foundation bracing to supply a total bracing package for a building.
The current technical review of our timber-framed building standard is limited by the rapid rate of change still occurring in the industry.
Numerous calls to the BRANZ Helpline indicate that many in the industry are having trouble with the ‘loaded dimension’ concept in NZS 3604:1999 Timber framed buildings. This article offers a visual explanation.
A BRANZ research project has investigated load transfer in timber framed buildings – and found a number of potential weak spots.
NZS 3604: 1999 Timber framed buildings is one of the most widely used Standards in building design. A BRANZ Study Report investigates how it is used, and asks whether it is time for a rethink.
When I began my engineering career, an old builder told me that the rule for lintels was ¾ inch depth per foot of span. Things have changed a bit since then…
