Retrofitting to resist extreme wind

By Graeme Beattie – 1 August 2008, Build 107

Strong wind causes damage to houses, particularly their roofs. A recent BRANZ study started by defining ‘extreme winds’ before developing retrofit solutions to ensure roofs on older houses are adequately secured.

Wind effects on buildings

By Graeme Beattie – 1 June 2010, Build 118

With the help of BRANZ data, the Riskscape joint project between NIWA and GNS aims to better predict the costs of damaging wind events on buildings.

Design prediction of wind-induced building motion

By Ian Wells – 1 April 2009, Build 111

There are sometimes significant discrepancies between the predicted and actual building sway in taller buildings. A new study aims to develop an improved methodology for wind design of buildings.

Are buildings ready for climate change?

By David Carradine, Nick Locke – 1 June 2022, Build 190

Research shows that, apart from some slight changes, light timber-framed buildings designed using our current standards should largely stand up to the increased wind speeds that climate change is expected to bring.

Maximum strength of house bracing walls

By Stuart Thurston – 1 February 2008, Build 104

A BRANZ research project has investigated load transfer in timber framed buildings – and found a number of potential weak spots.

Advanced façade systems

By Rob Teterin – 1 August 2020, Build 179

Emerging complex building façade designs can take up to a year to test, consent, fabricate and install. This makes it important for the project team to be on the same page from the start when it comes to design parameters.

Supporting heavy windows

By Stuart Thurston – 1 February 2011, Build 122

Heavier windows and drained and vented wall cavities mean loadings from windows are often offset from the timber framing. Recent BRANZ research checked that a modified support bar system can transfer the load back to the framing to prevent problems.

Distributing lateral loads in timber-framed buildings

By Ross Connon – 1 December 2007, Build 103

Creating a compliant bracing distribution system can be a challenge in today’s open plan house designs. Even if you don’t design them, it is still important to understand how bracing works.

Timber framing – rapid and reliable

By Nigel Isaacs – 1 August 2010, Build 119

Quick to go up and slow to come down, timber framing enabled New Zealand to house its rapidly growing population in the early 1900s and has proved to be an enduring building system.

Getting to grips with prefab

By Angela Eglinton – 1 April 2013, Build 135

In a new series, we look at the different types of prefab – from components, panels, modules and hybrid, to complete building – and how to apply them. First up are component-based systems.
