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.
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.
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.
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.
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…
You could be forgiven for getting the wind up about wind speeds, pressures and zones, but don’t worry. Here, we go back to basics to explain how they relate to one another.
‘Loaded dimension’ is an important term to understand when designing timber framed buildings. It ensures that the correct size of load-bearing timber is selected for each situation.
The area around the edge of a roof requires extra fixings to stop it lifting, but how much of the total roof area needs these extra fixings?
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.
