Abstract
This report presents a survey of the performance of wood-frame construction in a number of recent earthquakes. After a review of the dominant factors that affect the seismic behaviour of buildings, the following earthquakes are examined: Alaska, 1964; San Fernando, California 1971; Edgecumbe, New Zealand 1987; Saguenay, Quebec 1988; Loma Prieta, California 1989; Northridge, California 1994; and Kobe, Japan 1995. Wherever possible, the behaviour of buildings is related to the measured peak horizontal ground accelerations.

Abstract
Ce rapport présente une étude portant sur le comportement de bâtiments à ossature bois lors de récents tremblements de terre. Après un rappel des principaux facteurs qui affectent la résistance sismique des bâtiments, on examine les séismes suivants : Alaska (1964), San Fernando, Californie (1971), Edgecumbe, Nouvelle-Zélande (1987), Saguenay, Québec (1988), Loma Prieta, Californie (1989), Northridge, Californie (1994) et Kobe, Japon (1995). Dans la mesure du possible, le comportement des bâtiments est présenté en rapport avec les accélérations horizontales mesurées. Notre étude établit que, malgré certaines faiblesses spécifiques et les défaillances mécaniques correspondantes, les bâtiments en bois d'âges divers soumis à des accélérations horizontales de 0,6g ou plus ont dans l'ensemble résisté aux secousses sans dégâts mécaniques graves, et avec très peu de blessures ou de morts chez les occupants. Les critères de sécurité implicites des codes du bâtiment sont donc largement respectés. De plus, les bâtiments à ossature bois de construction récente ont généralement résisté aux secousses sans dommages visibles. Les quelques défaillances mécaniques observées étaient essentiellement liées à des faiblesses particulières : absence de contreventement, insuffisance structurale du premier niveau de construction, connexion trop faible avec les fondations, ou au fait que la force des secousses enregistrées avait largement dépassé les limites prévues au moment où le bâtiment avait été conçu. Les chercheurs et les professionnels de la construction travaillent actuellement à corriger les faiblesses observées, de manière à éviter les mêmes problèmes lors de futurs tremblements de terre. Le rapport présente les grandes lignes du programme de recherche de Forintek Canada Corp., qui vise à améliorer la résistance sismique des bâtiments à ossature bois et à appliquer ces améliorations par le biais de guides de conception et des normes. Il est notamment question d'études sur les assemblages, les murs de contreventement, la modélisation mathématique et la préparation de normes et de codes. On y trouvera enfin des recommandations pour le dépistage, l'évaluation et le renforcement des bâtiments qui ne satisfont pas aux normes sismiques canadiennes ou américaines actuelles. En conclusion, le document constate que la construction à ossature bois est capable de résister aux secousses telluriques importantes sans dommages graves et souvent sans dégâts en autant que les concepteurs, constructeurs et propriétaires respectent les règles de protection reconnues.

Abstract
In order to maintain the competitive advantage in existing and new markets situated in seismic and high wind zones such as the Pacific Rim and the southeastern U.S., it is proposed to study deflections in walls, floor and roof assemblies. The proposed project will also be very useful in: a) setting deflection criteria as will be demanded by performance-based codes, and b) responding to the inevitable transition to displacement-based seismic design.

Abstract
In the new 2005 edition of the National Building Code of Canada, the permissible deflections under earthquake conditions will be much more restrictive and could potentially become the governing factor for the design of wood frame construction. To proactively respond to the code changes, this three-year project was to develop design procedures for determining the stiffness or deflection of shearwalls and diaphragms under these extreme seismic and wind load events. While investigating the formulae for predicting deflections, issues related to the overall strength or load carrying capacity of shearwalls were also addressed. Using a “mechanics-based” approach, deflection formulae were developed for unblocked shearwalls, two-sided shearwalls (gypsum wallboard on one side and wood-based panels on the other side), and shearwalls without hold-downs. In collaboration with staff from the Canadian Wood Council, these deflection formulae will be submitted for implementation in the next edition of the Canadian Standard for Engineering Design in Wood (CSA O86), which in turn forms the basis for acceptance under the National Building Code. The work has also helped to address the following issues in the CSA O86: · Height limitations for unblocked shearwalls (currently capped at 2.44m) · The use of diagonal lumber as sheathing for walls and diaphragms. This information, which is particularly important in upgrading wood buildings to new code requirements, addresses concerns raised by designers. Technical information generated from this project was disseminated in the wood engineering community and CSA O86 committee meetings. Two papers entitled “Lateral Resistance of Tall Unblocked Shearwalls” and “Deflections of Nailed Shearwalls and Diaphragms” were presented at the 8th World Conference on Timber Engineering in Lahti, Finland in June 2004. An article entitled “Racking Performance of Tall Unblocked Shearwalls” has been submitted to the ASCE Journal of Structural Engineering for publication. Another article entitled “Performance of Shearwalls with Diagonally Sheathed Lumber” is being prepared and will be soon submitted to the ASCE Journal of Structural Engineering. By proactively responding to future design code changes, this project will allow the construction industry to take advantage of various shearwall options in their designs of wood frame buildings, and will assist the wood products industry to maintain its competitive advantage in existing and new markets situated in seismic and high wind zones such as those around the Pacific Rim and in the South Eastern United States.
