Content:
BRANZ presented a ventilation (space and roof) and a NZS 3604:2011 bracing seminar to a limited number of main centres early in 2017. Subsequently there were a number of requests to bring the key components of each seminar to the regions. While this seminar abridges both of those seminars, the key elements of content have been retained.
Ventilation Component:
Ventilation can be the difference between a building that is dry and healthy and one that is not. For what appears to be a seemingly simple process, there are a number of intricacies that lead to many buildings being constructed with inadequate ventilation. This seminar covers roof and living space ventilation based on BRANZ research. In each case, we'll talk about the possible moisture issues faced through inadequate ventilation and the solutions to address them. The topics covered include:
- Living space ventilation:
- Clause G4 and ventilation options
- Drying out damp houses
- Effective duct and fan selection
- Roof space ventilation:
- When is roof space ventilation required?
- Simple roof space ventilation calculation
- Ventilation details
Bracing Component:
Timber-framed buildings are required to be braced to resist horizontal loads from wind and earthquakes. This seminar takes a back-to-basics approach to bracing, taking you through the steps that need to be addressed using examples to calculate the bracing required for framed walls. We will start by looking in more detail at why we need bracing and what information is needed to begin the process of calculation wall bracing. Topics will include:
- Why we need bracing
- Making bracing easier
- The steps to work out bracing demand for wind and earthquake
- Bracing capacity and how it is determined
- Bracing lines and distributions of bracing
These principles will then be applied to three simple design examples.
Learning Objectives:
To have an understanding of:
- The Building Code requirements for ventilation
- How ventilation can be achieved
- The key requirements to achieve satisfactory bracing of timber framed buildings
- Why we need ventilation in living and roof spaces
- Why we need to brace buildings
Roger Shelton- Roger Shelton is an experienced structural engineer who has been with BRANZ for over 20 years. Before that he worked for consulting engineers and architects in New Zealand and Hong Kong, and started his career with the Ministry of Works in Christchurch. He was part of the committee that reviewed NZS 3604 "Timber framed buildings", both in 1999, and in 2010, and is an active member of several other NZ and ISO Standards Committees.
Roger was a member of a joint New Zealand/ Australian reconnaissance team which studied the building damage in Kobe, Japan, immediately following the 1995 earthquake. He also took part in reconnaissance after the Gisborne
earthquake in 2007, and the Tohoku, Japan earthquake and tsunami of March 2011.
His involvement in the series of Christchurch earthquakes and aftershocks ranged from building evaluations for Civil Defence in the immediate aftermath, to residential housing damage surveys for BRANZ, and participation in the DBH Engineering Advisory Group.
