Abstract
This paper will present the most recent developments in the statistical modeling of the mechanical properties of structural lumber. In addition to providing a summary of testing programs and model development (primarily in North America), two advanced stochastic modeling approaches will be described. The first is the generation of vectors of correlated lumber properties and the second is the stochastic modeling of the creep mechanism in wood. These recent probabilistic approaches to the modeling of lumber properties have been employed in reliability studies which have formed, and continue to form, the basis of the new load and resistance factor design specification for wood construction in the United States. Similar work is being conducted in Canada, Europe, Australia and New Zealand.
