Abstract
This paper re-examianes the issues associated with specifying wind loads for the safe design of low buildings. After establishing the rationale for the current Canadian Code specifications, they are reviewed in the light of the results of a recently completed wind tunnel study that has broken new gorund; wind loads have been measured in simulated complex environments chosen statistically to represent the spectrum of possible real situations. The results exhibit large variability, but can be analyzed and copared to code requirements using reliability theory. In particular, the role ofthe sometimes misunderstood "0.8 factor" is reviewed and compared with alternative approaches.
