“…A quantitative safety goal should be interpreted with some flexibility, as the quantitative safety goal is a 'goal' only and other nonprobabilistic criteria are also important in judging the overall acceptability of risks (for more details, see Stewart and Melchers 1997, Reid 2000, Melchers 2001). …”

“…The global quantitative safety goals suggested by Pate´-Cornell (1994), Reid (2000) and others are in general agreement with those shown above. There is public aversion to risks associated with multiple casualties and catastrophic events, hence safety goals for societal risks may be represented in terms of an F-N curve, which is a plot of cumulative frequency (F) of N or more fatalities versus number of fatalities (N).…”

“…However, a regulatory safety goal such as this should be interpreted with some flexibility as the regulatory safety goal is a 'goal' only and other non-quantifiable criteria may be important also in judging the overall acceptability of risks (eg. Stewart and Melchers 1997;Reid 2000;Melchers 2001). Past experience shows that it is likely that decisions may be made (or over-ruled) on political, psychological, social, cultural, economic, security or other non-quantifiable grounds.…”

This paper seeks to discover whether aviation security measures are costeffective by considering their effectiveness, their cost and expected lives saved as a result of such expenditure. An assessment of the Federal Air Marshal Service suggests that the annual cost is $180 million per life saved. This is greatly in excess of the regulatory safety goal (societal willingness to pay to save a life) of $1-$10 million per life saved. As such, the air marshal program fails a cost-benefit analysis. In addition, the opportunity cost of these expenditures is considerable, and it is highly likely that far more lives would have been saved if the money had been invested instead in a wide range of more cost-effective risk mitigation programs. On the other hand, hardening of cockpit doors has an annual cost of only $800,00 per life saved, showing that this is a cost-effective security measure.

“…Society accepts that some buildings will fail during catastrophic events. It is estimated that accepted risks of death are 0.14 ϫ 10 -6 and 4 ϫ 10 -6 per annum for structural building failures and building fires, respectively (Reid 2000). Also, societal toleration of individual events affecting many people is much lower than the toleration of an equal number of individual fatalities, e.g., acceptable risks of death 2 ϫ 10 -6 and 300 ϫ 10 -6 per annum from earthquakes and road accidents, respectively.…”

Since before recorded history mankind has used timber for construction and, in "tree rich" rural societies, timber has remained a primary construction material ever since. This reflects the ease with which it can be sourced, its excellent mechanical properties, light weight and easiness to shape. However, over the centuries there has developed widespread aversion within the world's burgeoning urban areas to using timber, because construction practices led to poor fire performance if timber was used. Urbanized societies essentially forgot over recent centuries that if used properly timber is a high-performance construction material. Modern advances in construction know-how and fire suppression techniques coupled with concerns over sustainability of other options, have created conditions wherein timber is re-emerging as a major construction material. Timber has begun to be used in construction of relatively tall urban buildings, rather than being regarded as only suitable for small buildings, and occasional large showpieces that are well isolated from neighbouring structures. This paper summarizes the story of the discovery, diminution and beginnings of re-emergence of timber as a major structural and construction material, and links that to contemporary research at the University of New Brunswick and collaborating institutions.Key words: design, fire, fire engineering, performance-based design, seismic response, structural design, structural response, timber, timber engineering, urbanization, wood RÉSUMÉBien avant que ne s' écrive l'histoire, le genre humain utilisait le bois à des fins de construction et dans les sociétés rurales « riches en arbres », le bois est demeuré un matériau de construction de premier plan jusqu'à ce jour. Cela découle de la facilité avec laquelle il peut être extrait, ses excellentes propriétés mécaniques, son poids léger et sa facilité à être façonner. Cependant, au cours des siècles, il s' est développé une aversion répandue dans toutes les zones urbaines en développement envers l'utilisation du bois, parce que les pratiques de construction ont entraîné des performances déplorables lors d'incendie lorsque le bois était utilisé. Les sociétés urbanisées ont essentiellement oublié au cours des derniers siècles que lorsqu'il est adéquatement utilisé, le bois constitue un matériau de construction à haute performance. Les progrès récents en technologies de construction et en techniques de suppression des incendies ajoutés aux questions sur la durabilité des autres options, ont créé les conditions par lesquelles le bois émerge à nouveau en tant que matériau de construction de premier ordre. Le bois commence à être utilisé pour la construction d' édifices urbains en hauteur, plutôt que d' être considéré comme étant réservé à de petits bâtiments et occasionnellement à des structures apparentes de grandes dimensions bien isolées des constructions avoisinantes. Cet article résume l'histoire de la découverte, la diminution et l'amorce de la nouvelle émergence du bois en tant que matériau ...
