报告题目： Modern Timber Buildings and Fire resistance and
earthquake resistance of post-tensioned multi- storey timber buildings
欢迎广大同学参加。
报告摘要：
This seminar describes the huge opportunities for engineered wood to be used
for constructing modern timber buildings. This is essential for a greener
future on our planet, to reduce world-wide dependence on energy and CO2
intensive materials like concrete and steel, by moving to engineered wood
for growing populations.
To promote the design and construction of engineered timber buildings, it is
necessary to develop new wood-based materials, to manage the wood supply
chain, and to encourage research and innovation by design professionals.
The seminar describes the rebuild of Christchurch New Zealand following the
2011 earthquakes. New Zealand has a mature forest industry, largely based on
exotic plantations of radiata pine, and a growing wood processing industry,
focussing on laminated veneer lumber (LVL). Several new post-tensioned
timber buildings will be shown.
New Zealand structural engineers are leading the world in innovative low-
damage seismic design and performance-based design of multi-storey timber
buildings for fire safety, supported by a successful industry-government
research partnership.
Demonstration buildings are needed to catch the imagination of investors and
to increase the confidence of the supply chain. New timber buildings have
been proposed for Chicago (42 stories), Vancouver (30 storeys), and a 14
storey building in Ottawa, with the support of the Canadian government,
following the New Zealand examples.
----------------------------------------
Post-tensioned timber is a construction technique that has been developed in
recent years in New Zealand. When utilised in new buildings, it can lead to
significant advantages, including improved lateral load resistance. Post-
tensioning uses high-strength steel tendons that are stressed during
construction to apply a compressive stress to the members in order to
increase the strength, reduce deflections and to tie adjacent members
together. Box beams made from LVL allow a very efficient use of engineered
timber materials. However the thin webs used in box beams can result in high
shear stresses in the webs, which leads to reduced fire resistance. This
paper will describe the 2011 Christchurch earthquake and opportunities for
re-building the city with multi-storey timber buildings.

Prof. Andy Buchanan is Professor of Timber Design at the University of
Canterbury, in Christchurch, New Zealand. He is a structural engineer with
special interests in timber engineering, fire safety and earthquake
engineering. His current research includes design and structural performance
of large timber structures including innovative post-tensioned timber
buildings designed to resist major earthquakes and fires.
Andy has a B.E.(Honours) degree from the University of Canterbury (1970), a
Masters degree from the University of California (1972), and a Ph.D from the
University of British Columbia, Canada (1984).
Prior to joining the University of Canterbury in 1987, he was a consulting
engineer in private practice, involved in structural design of a wide range
of buildings, initially with Holmes Consulting, and later with Buchanan and
Fletcher Ltd. He was made a Distinguished Fellow of IPENZ in 2011.
He is the author of Structural Design for Fire Safety (John Wiley & Sons,
2001) and the Timber Design Guide (NZ Timber Industry Federation, 2007). He
is past President of the New Zealand Timber Design Society, and currently
Research Director of the Structural Timber Innovation Company Ltd.
