Canadian Wooden Dome (CWD) is an innovative orthotropic, monolithic modular sectional building system. The main frame of these structures is built using mill trim ends that are normally chipped or used for finger-jointing. The structure, in comparison to conventional wood-frame single-family housing, has a rapid manufacturing process, and quick, on-site assembly attempts to reduce overall construction time. Presented with these advantages and the uniqueness of the wooden-dome system, a technical study was initiated to investigate the structural performance of the modular wooden dome in earthquake-prone areas and to examine its load resistance to heavy snow. This paper describes the results from a series of static and dynamic load tests conducted on the CWD as part of this study. The test results generally indicated that based on the structural performance of the CWD under static and dynamic loads, the CWD could be an alternative to the conventional wood-frame construction system. The test results are then compared with those obtained from the tests conducted on conventional single-family wood-frame houses as part of the Earthquake 99 (EQ-99) Woodframe House Project at The University of British Columbia. The seismic performance of the CWD was superior to that of the nonengineered housing system and comparable to that of the engineered wood-frame housing system. Le système de construction « Canadian Wooden Domes (CWD) » est un système modulaire novateur de construction sectionnelle, monolithique et orthotrope. Le cadre principal de ces structures est bâti en utilisant des éboutures qui sont normalement mises en copeaux ou utilisées pour des aboutages. La structure, par rapport à celle des maisons unifamiliales conventionnelles à ossature de bois, se fabrique rapidement et l’assemblage rapide sur le site tend à diminuer le temps de construction global. En tenant compte de ces avantages, une étude technique a été lancée pour examiner le rendement de cette structure unique de dôme en bois modulaire dans les zones sujettes aux séismes et sa résistance à une charge de neige abondante. Le présent article décrit les résultats d’une série d’essais en charge statique et dynamique effectués sur les dômes en bois dans le cadre de cette étude. En se basant sur le rendement structural de ces dômes en bois sous des charges statiques et dynamiques, les résultats indiquent généralement que les dômes en bois pourraient être une solution de remplacement au système traditionnel de construction à ossature de bois. Ces résultats ont ensuite été comparés à ceux obtenus lors d’essais effectués sur des maisons unifamiliales à ossature de bois traditionnelles dans le cadre du projet « Earthquake 99 Woodframe House Project » réalisé antérieurement à l’Université de la Colombie-Britannique. Par rapport aux structures à ossature de bois traditionnellement mises à l’épreuve, le dôme en bois présentait un rendement sismique supérieur à celui des systèmes non techniques et un rendement sismique similaire à celui des systèmes techniques à ossature de bois.
