  Abstract

    Wood is the one of the most common and oldest structural materials, but its use has been limited to low-rise (less than 4 storeys) residential construction in many parts of the world. In the past 20 years, a number of high performance structural wood products have been developed that are viable alternatives to steel and concrete in large engineered structures. At the same time, there is a world-wide interest by architects and engineers to specify wood in construction projects due to a number of factors: 1. Wood has a low environmental footprint because it is renewable, requires low energy and generates low level of pollution during manufacturing; 2. Its higher strength-to-density ratio leads to lower structure mass and therefore lower foundation cost and seismic force; 3. Wood structural systems such as wall and floor, can be prefabricated in the factory easily, thereby reducing construction time and on-site labour. A 9-storey wood building has recently been erected in London, UK, and the trend is to construct even taller buildings. Two 20-storey wood building are at a planning stage in Europe. In order to support this market expansion opportunity for wood, much research is required to develop appropriate design tools that can be used by engineers and architects to design large and tall wood structures, and provide evidence that performance of large and tall wood structures meets the building code requirements for fire, structural, durability, energy and serviceability performance. As one of the largest producers of wood building products in the world, Canadian researchers have been active in research that are aimed at addressing these issues. This presentation will focus on structural performance of structures i.e. wood engineering and consist of 2 parts. The first part will outline the reasons for the increased interest in specifying wood, summarize the search needs, and briefly review a few research projects in Canada as an illustration of the types of research that are being conducted. The second part will review a few wood engineering research projects at the home university of the speaker, University of New Brunswick.

 

  

Dr. Y. H. Chui, University of New Brunswick, Fredericton, New Brunswick, Canada

    Dr. Chui received his BSc degree in Civil Engineering and PhD degree in Timber Engineering from the UK. He joined the Faculty of Forestry, University of New Brunswick as a faculty member in 1993. He was Assistant Dean of the Faculty between 1997 and 1999 and Director of its Wood Science and Technology Centre between 1997and 2008. In 1999 he received the inaugural Young Engineer Award from the Forest Products Society. In 2009, he was appointed by the Natural Sciences and Engineering Research Council of Canada (NSERC) as Scientific Director of a $5.3 million Research Network on Innovative Wood Products and Building Systems.  Dr. Chui is an internationally known expert in timber engineering and engineered wood products. He has published over 130 refereed articles in journals and conference proceedings on these topics. Dr. Chui is active in the development of codes and standards in North America and internationally. He is a member of a Standing Committee of the National Building Code of Canada, and a member of three Canadian and American standards technical committees, as well as a member of an ISO committee on timber structures.
